What is Beamforming and Will it Make Wireless Better?

The tech world is always evolving and looking on to the next thing – To be better, quicker, stronger. Wireless and Wi-Fi technology is no different – We want to be able to access the best possible connection – Strong, reliable and fast. 

So how does beamforming help with this? 

What is Beamforming? 

Beamforming makes Wi-Fi and 5G connections more precise by utilising the science of electromagnetic interference. 

The original concept of beamforming has actually been around since the 1940’s. In current communication standards, this tech is playing a pivotal role in improving Wi-Fi and 5G among others. 

When beamforming is used alongside MU-MIMO (Multi User Multiple Input, Multiple Output) tech, it can help users to boost their data speeds by accessing more precise connections. 

How Does Beamforming Work?

Using Beamforming means that the resulting connection is faster and more reliable. It works by focusing a wireless signal to a specific receiving device. In this instance, the signal is more focused rather than being spread in all directions like, for example, a broadcast antenna. 

Unless they are blocked by a physical object, electromagnetic waves from a single antenna will radiate in all directions. To specifically target a beam of electromagnetic energy in order to focus the signal in a certain direction, you can use multiple antennas close together to broadcast the same signal at slightly different times. 

These overlapping waves will cause interference which can be good (cause the signal to be stronger) or bad (cause th signal to become weak or undetectable). 

When done constructively and correctly, the electromagnetic waves can be focused to a specific direction – Beamforming. 

We’re going to spare you the mathematics behind the process of beamforming – It’s extremely complex. If you’re a big maths geek you can look it up online and try and wrap your head around it. 

We mentioned earlier that the actual technqiue of beamforming isn’t a new concept and has been around for over 80 years. Wi-Fi and 5G aren’t the only technologies that can benefit from beamforming – Any type of energy that travels in waves can use the concept, including sound. 

Beamforming was originally developed to help in World War II by improving sonar and is still an important part of audio engineering today. 

But let’s get back to our niche – Wi-Fi and 5G tech is where our interest in beamforming lies. 

How does beamforming help Wi-Fi 6?

Wi-Fi 6 is the latest generation of Wi-Fi (also known as 802.1ax but thankfully now with improved naming via the Wi-Fi Alliance!). It succeeds the 802.11ac Wi-Fi standard (now more aptly named Wi-Fi 5). 

In terms of Wi-Fi standards, beamforming has actually been around since Wi-Fi 4 but seen improvements in both Wi-Fi 5 and Wi-Fi 6. Beamforming uses MIMO technology to be able to send out multiple, overlapping signals. 

Since 2016, the use of beamforming with Wi-Fi 5 meant that different receivers can work with different routers, hence making the beamforming techniques used in Wi-Fi equipment are vendor-neutral. 

Beamforming can also be used alongside MU-MIMO technology, allowing multiple users to communicate simultaneously with multiple antennas on the router. Beamforming used in this way ensures that each of the connected clients are efficiently targeted by the router. Data rates and range for signals to specific clients are also improved with Wi-Fi 6 through the increased number of antennas (from 4 to 8). 

What about Wi-Fi 7? 

In the world of tech we’re always looking ahead to the next thing – So what about beamforming and WI-Fi 7? Unsurprisingly, beamforming will also be a core part of Wi-Fi 7 (802.11be).  

Coordinated beamforming will use the capability of modern multi-antenna access points to spatially multiplex their stations, as well as making adjacent neighbouring non-associated stations void.

This technique can actually be used without beamforming via a joint multi-access point sounding scheme. However, a coordinated beamforming process can take advantage of a simpler sequential sounding procedure which will be a part of Wi-Fi 7. 

As each station transmits and receives data to and from a single access point, coordinated beamforming does not require joint data processing. This helps diminish backhaul needs. 

Whilst this limits complexity, it also delivers substantial throughput and latency enhancements.

Other improvements that we’ll see with Wi-Fi 7 and coordinated beamforming will hopefully include access to gigabit speeds and low-latency communications for more busineses and consumers in various applications. 

How does beamforming help 5G? 

With the prevalance of 5G increasing with the roll out of networks for smartphones and other WANs, we’ll be seeing beamforming as a core part of the new technology. 

5G frequencies are unfortunately more prone to being disrupted by objects causing interference, like walls or other similar barriers for example. This is because 5G operates on the millimetre wavelength (mmWave) frequency. 

Beamforming helps with this by creating a more reliable connection. It does by allowing the transmitter to focus the transmission in a specific direction, as explained above. This means the signal is directed towards, for example, a mobile device, vehicle or other IoT device. 

Working with MIMO, beamforming can improve throughput and efficiency by directing beams from a 5G base station in both horizonal and vertical directions  via large numbers of antennas. 

What are the pros of beamforming?

Wi-Fi and 5G tech can really benefit from beamforming. 

  • Information can be transferred quicker and with fewer errors because the signal is of a higher quality due to being focused in a specific direction
  • Users trying to connect to other signals can benefit from less interference because beamforming can reduce and even stop broadcasting in other directions

Are there any cons when it comes to beamforming? 

Whilst beamforming can have benefits for wireless technology, some limitations can lie in the actual process of doing it. 

  • Beamforming requires big computing resources. In some situations, the beamforming calculations would require time and power resources that could make the resulting benefits less worth it
  • Improving affordability means that beamforming techniques are being built into wireless equipment on the consumer market as well as enterprise-grade wireless hardware
  • For the best performance, the transmitter and receiver need to be quite close together. The further away the receiver is from the transmitter, the more the benefits diminish

It’s pretty clear to see that beamforming is a big part of the wireless world, especially in terms of Wi-Fi 6 (and 7) as well as 5G.

Is Wi-Fi HaLow a Better Wireless Option than Wi-Fi 5 and 6 for IoT?

Wi-Fi HaLow has quite the list of benefits when it comes to Internet of Things applications. With high bandwidth, long range, unlicensed spectrum, low power, and less complexity than Wi-Fi 5 and Wi-Fi 6, Wi-Fi HaLow could well be a better option. 

What is Wi-Fi HaLow?

Image from https://www.wi-fi.org/discover-wi-fi/wi-fi-certified-halow with thanks

The Wi-Fi Alliance has coined the IEEE 802.11ah Wi-Fi standard as Wi-Fi HaLow, as it will be known in the wireless market. It was approved back in September 2016, and then published in the following May. 

Wi-Fi HaLow is a new version of traditional Wi-Fi, offering:

  • Long range
  • Low power
  • Low speed

Wi-Fi HaLow is most likely to be deployed within the Internet of Things market, on things such as:

  • Sensors
  • Wearables
  • M2M (Machine to Machine) applications
  • Smart buildings
  • Smart cities

What are the benefits of Wi-Fi HaLow?

Wi-Fi HaLow has the ability to connect low-bandwidth devices to IP networks, including the internet. It also supports enough bandwidth to handle HD Quality video.

Perhaps one of the great things about Wi-Fi HaLow is its usefulness in rural communications as well as offloading cell phone tower traffic. 

Whilst there are similar low-power standards, like 802.11af, there are differences. For example, 802.11af operates in the television white space spectrum in VHF and UHF bands, whereas Wi-Fi HaLow is easier to deploy due to operating in the unlicensed bands. 

There are of course similar technologies that utilise the unlicensed spectrum, but Wi-Fi HaLow also has advantages over some of them due to them being built on proprietary standards. 

The requirement of getting proprietary hardware in order to get IP connectivity to the client devices also means that some other similar technologies are more complicated to deploy than Wi-Fi HaLow.

HaLow is intended to make deploying IoT devices easier.

Why is Uptake for Wi-Fi HaLow Slow?

Despite the advantages laid out above, the uptake for Wi-Fi HaLow has been pretty slow. 

If you have a look on the Product Finder section of the Wi-Fi Alliance’s website, you’ll find only 3 companies that are listed as having certified Wi-Fi HaLow products. 

And if the uptake is so low, it begs the question…

So Why Use Wi-Fi HaLow?

The advantages we talked about above hint at where Wi-Fi HaLow can be used effectively. 

Wi-Fi HaLow Utilises Licence-Exempt Frequencies

As you are probably aware, the majority of Wi-Fi technologies, including Wi-Fi 5 and Wi-Fi 6, operate at frequencies in the 2.4 and 5 GHz bands. 

The difference with Wi-Fi HaLow is that it utilises licence-exempt frequencies that are below 1 GHz. 

Wi-Fi HaLow Has Longer Range

Due to Wi-Fi HaLow having lower frequencies, it also has longer signal ranges. Not only that, but the signal itself penetrates walls and other materials better. 

Due to these reasons, Wi-Fi HaLow can travel much further, even managing distances of over half a mile (0.62 miles to be precise). 

Wi-Fi HaLow Devices Don’t Hog Bandwidth and Need Less Power

Wi-Fi HaLow devices can use lower power radios as they’re not hogging bandwidth with high performance. In other words, the devices wireless connectivity uses very little power which in turn means that they have a long battery life. Some devices can even last more than 5 years! 

Got devices on the network that need more throughput? With Wi-Fi HaLow you can give hundreds (if not thousands) of IoT wireless devices their own band to operate in – Enabling you to reserve the higher bands for those higher throughput devices. This could in turn have a positive impact on your overall network performance.

In this way, Wi-Fi HaLow compliments traditional Wi-Fi very well by enabling your network engineers to move lower bandwidth clients off the main Wi-Fi network. 

Depending on the AP capabilities and client-device specifications, Wi-Fi HaLow can still provide enough throughput for HD-quality video cameras in some scenarios, despite being designed for lower bandwidth applications. 

Do We Have the Infrastructure for Wi-Fi HaLow?

In short, yes! It’s pretty straightforward to get going with Wi-Fi HaLow. 

Whereas other similar technologies require proprietary controllers, hubs or gateways, Wi-Fi HaLow doesn’t need any of this. 

It’s as simple as plugging a HaLow Ap into a traditional LAN and clients can connect to IP-based networks including the internet. 

Alternatively, they could choose a gateway device with 4G LTE connectivity to the WAN.

Does traditional Wi-Fi support HaLow?

Currently, the HaLow band is not supported by traditional Wi-Fi like 2.4 GHz and 5 GHz. 

But, due to the longer range of HaLow, an AP deployed in the right location could mean signal coverage for an entire multi-floor office building or warehouse. 

Of course, that would also depend on:

  • Desired data rates for clients
  • Transmit powers
  • Antennas
  • Interference

To take the signal even further, without using a wired connection, you can also deploy Wi-Fi HaLow in a wireless-mesh mode. 

What are the Data Rates like for Wi-Fi HaLow? 

Bandwidth can be increased via channel-width options on Wi-Fi HaLow devices just like traditional Wi-Fi. Between 1MHz and 16MHz there are 5 channel widths, but not all devices support all the widths. 

When we talk about channels, the transmissions travel further the narrower the channel is, but at a slower data rate. 

For example, for a long range over the course of 1km on just 1MHz channel, with a bit of RF attenuation, you would see a data rate of approximately 150 kbps. 

With a shorter range and/ or a line of sight, you could in theory get 86.7 Mbps with 16 MHz channels and short guard intervals. 

One trial carried out at sea with no radio interference achieved 2 Mbps of UDP throughput at 3 km with line of sight. With this in mind, with ideal conditions could expect a data rate of a few Mbps for approximately 1.5 km range. 

How is Wi-Fi HaLow Affected by Interference?

Wi-Fi HaLow aren’t not the only unlicensed users and devices on the 900 MHz band. Historically, this band was rather crowded with cordless phones as well as amateur radio operators, although whilst they have the right to use the band they are not the primary users of the band and hence have to accept interference from other sources. 

Interference when using Wi-Fi HaLow is unlikely to cause significant issues in comparison to how many Wi-Fi 5 and Wi-Fi 6 devices are using the 2.4 GHz and 5 GHz bands. 

The competition for airtime is also a lesser concern because unlike traditional Wi-Fi devices, HaLow devices tend to deliver smaller amounts of data and less frequently. 

Is Wi-Fi HaLow Secure?

Wi-Fi HaLow is just as secure as traditional Wi-Fi devices due to supporting the same WPA3 (Wi-Fi Protected Access) security and Wi-Fi Enhanced Open functionality. 

Some devices may also support the enterprise mode of WPA3 with 802.1X authentication. Some HaLow devices may also support the legacy WPA2 security even though it isn’t required for Wi-Fi Certified products.

Is HaLow ready for enterprise deployments?

Despite there being few Wi-Fi Halow devices on the market just yet, reports are saying that they are ready for enterprise deployments now. 

Our recommendation, as with any Wi-Fi network, is to carry out a Site Survey before designing and deploying a Wi-Fi HaLow network.

For many network engineers, this is a new and unfamiliar technology so it’s imperative you do plenty of live testing and analysing to make sure the network will work effectively. This is especially important if you are going to be using Wi-Fi HaLow to serve higher bandwidth clients or over long distances. 

Strong Growth of Enterprise WLAN Market in 2023 Q1 

The International Data Corporation (IDC) Worldwide Quarterly Wireless LAN Tracker has reported that between the first quarter of 2022 and Q1 of 2023, the Enterprise Wi-Fi market has grown by 43%. 

What’s Behind the Growth of the Enterprise WLAN Market?

The driving force behind the Enterprise WLAN market growth is in part down to the easing of component shortages. 

There has also been a significant demand for the upgrades and expansions that come with Wi-Fi 6 and Wi-Fi 6E. 

You can find further details on this in IDC’s latest market report. 

Wi-Fi Market Back With a Vengeance

Previously, the right business to be in might have been as a service provider or consumer Wi-Fi. But we’ve come a long way since 2020, and from just last year even. The IDC reports that the consumer Wi-Fi segment has decreased by 8.8% for the quarter year-on-year.

The enterprise Wi-Fi market however is back and booming and showing itself to continue to grow year-on-year. 

The IDC’s recent report showed that the Enterprise Wi-Fi market grew by 43% in Q1 for 2023 (year on year). This sector is worth a huge 2.8 billion dollars. 

Is the Growth of Enterprise WLAN Market Down to Wi-Fi 6?

Of the Enterprise WLAN sector revenue, Wi-Fi 6 made up 78.6%. 

In addition to that, the adoption of Wi-Fi 6E is up by 14% from that last quarter of 2022. This continued growth has taken a 10.4% share of the AP market in Q1 of 2023. 

Cisco Expands Market Dominance

At the end of the first quarter of 2023, Cisco continued to take their Enterprise Wi-Fi market share with 47.1%. Their revenue has risen 62.7% year on year – Their Enterprise Wi-Fi revenue for this quarter was 1.3 billion US dollars. 

Also doing well in the Enterprise Wi-Fi market is HPE_Aruba (Aruba Networks). They have grown by 39.5% year on year for Q1 of 2023. The IDC reports they have a market share of 16%.

What is 6GHz Wi-Fi?

Did you know that following the historic decision by USA’s FCC in April 2020 to release 1200 MHz of bandwidth in 6 GHz space for unlicensed use, UK regulators cleared unlicensed wireless usage in the 6 GHz spectrum to give 6GHz WiFi a huge boost back in July 2020. 

 

This regulatory go-ahead enables your router to broadcast over the 2.4GHz and 5GHz bands. What does this mean in real life terms? Simply, it means there are now a lot more open airwaves that routers can use to broadcast Wi-Fi signals. This in turn means faster, more reliable connections from the next generation of devices.

 

This is the biggest spectrum addition in over 30 years – In fact, since the FCC cleared the way for Wi-Fi back in 1989. Pretty huge right? It means the space available for routers and other devices have quadruple the amount in this new spectrum. This means a lot more bandwidth for the user and less interference for their devices. 

 

For the past 20 years we’ve had the Wi-Fi Alliance that oversees the implementation of Wi-Fi. This change in the spectrum is the most ‘monumental decision’ during their existence. You’ll be seeing this implementation as Wi-Fi 6E, with more and more enabled devices becoming available. 

 

Will Wi-Fi 6E fix my bad Wi-Fi? 

 

There’s a good chance that spectrum congestion has interfered with your ability to connect to your Wi-Fi network in the past. When there are a lot of devices all trying to connect over the same band of frequencies, some devices will drop out. Have a look at your local area for Wi-Fi networks – If there is a long list, that could be why you’re struggling with a slow connection and less than favourable reliability. This is because there are too many competing signals, which stops your device getting through. It’s hoped that gains in 6GHz performance will last, even when they are more widely used than they are now. 

 

Not only does Wi-Fi 6E offer new airwaves for routers to use, they are also more spacious airwaves that have less overlapping signals which can cause problems on some other Wi-Fi channels. 

 

The new spectrum doesn’t use any of the previous spectrum, yet offers space for up to 7 maximum-capacity Wi-Fi streams which can all be broadcast simultaneously without causing interference with each other. 

 

Here’s the geeky bit… The UK telecoms regulator, Ofcom, made it possible for home Wi-Fi networks to harness 500MHz of radio spectrum frequency in the new 6GHz band, which will significantly boost the speed of licence-exempt indoor home wireless networks via Wi-Fi 6/6E. 

 

What is 6GHz? 

 

Basically, Wi-Fi works by broadcasting over airwaves that are open for anyone to use. Previously, this was over two bands: 2.4GHz and 5GHz. This third band, 6GHz, is quadrupling the available space for traditional Wi-Fi. 

 

What do the numbers mean? 2.4GHz can travel further, but 6GHz travels faster. The main thing however is that the number of airwaves available on the6GHz band is quadruple what has been available before. Exciting stuff! 

 

On a personal ‘how will this affect me’ level, it means that if you live in a block of flats, and you are the first person to get a 6GHz router, then you won’t be competing with anyone for a connection. The great thing is that even as 6GHz routers become more popular, it’s likely that signals will stay faster and stronger than previously as it’s a more spacious spectrum.  

 

Will Wi-Fi 6E be faster?

 

It’s not quite as straight forward as that, but Wi-Fi 6E will sort of be faster. Theoretically, 6GHz Wi-Fi has the same top speed as 5GHz Wi-Fi. The maximum Wi-Fi 6 standard speed is 9.6 Gbps. Now, you’re not going to actuall get that speed in real life, however having access to the new airwaves could well increase your speed. 

 

The available spectrum at 5GHz means that Wi-Fi signals aren’t as large as they could be. Whereas, it’s thought that routers at 6GHz will broadcast at the current maximum allowable channel size. That in itself, means a faster connection. 

 

These new networks could see smartphone Wi-Fi connections hit 1–2 Gbps. You might be wondering how this compares to 5G – Indeed, these are the speeds expected from millimetre-wave 5G. However, that has very limited availability. 

 

Remember that your internet speeds will also always depend on / be limited by your provider. But it could still be a huge jump for connectivity.  

 

Can I buy Wi-Fi 6 devices?

 

Here in the UK we started to see Wi-Fi 6 devices creep onto the market in the last year or so, once the Wi-Fi Alliance started offering certification for Wi-Fi 6E. Deployment has been slow and steady, with more Wi-Fi 6 enables devices appearing bit by bit. We’re on course for the next generation of Wi-Fi networks.

 

Wi-Fi 6E enabled devices are most seen in smartphones and then tablets, with TV’s likely to follow suit. We use our phones for almost everything, so it’s no surprise that it’s this device that will be top of the list for Wi-Fi 6E. 

 

How do I know if a device supports Wi-Fi 6E?

 

The most widely used Wi-Fi standard on current devices is probably still Wi-Fi 6, the standard previous to Wi-Fi 6E, which you could still see on the box of a new device. This isn’t such a bad thing – It means that the device supports that Wi-Fi standard and offers efficient Wi-Fi performance. 

 

What you should probably start looking out for when buying a new device is Wi-Fi 6E – It’s this one that is extended into the 6GHz band. All devices, like smartphones, tablets, laptops and routers should have backward compatibility – Meaning they will work with any previous Wi-Fi standard to the one that’s stated on the box. This means that you can enjoy available connections even when Wi-Fi 6E isn’t available. 

 

Be aware that even if you buy a Wi-Fi 6E compatible device, you will enjoy the benefits of that when you use it with a Wi-Fi 6E router. 

 

6GHz will become an integral part of Wi-Fi 6 and future generations of Wi-Fi. This means that at some point, you will have to replace your devices with ones that are Wi-Fi 6E compatible to be able to enjoy all the benefits the extra spectrum has to offer. 

 

Due to the Wi-Fi Alliance certification programme, only efficient Wi-Fi 6 devices will be certificated. 

 

It’s worth bearing in mind that the 6GHz spectrum does have some existing licensed users. This means that particularly in outdoor spaces,  Wi-Fi will have to work around them. Outside, routers will need to use something called an “automated frequency control” system. This ensure that they don’t interfere with these existing 6GHz users. Because that means less space to broadcast, there could be degradation of overall performance in some areas.

 

Does Wi-Fi 6E have anything to do with 5G? 

 

We touched on this earlier, but no, they don’t have anything to do with each other really. It just happens that both of these networks are being spoken about a lot, simultaneously. 5G is everywhere, is it not!

 

We keep saying about Wi-Fi 6E being a new spectrum, but really it’s not new, it’s always been there, it’s just been unlicensed. Now, people can use the 6GHz spectrum without a license in their homes. 

 

This also means that other technologies could try to make use of the 6GHz band, which could in turn take up some of the space that Wi-Fi wants to use. 5G is one of the technologies that could be a rival for the space on the 6GHz band. 

 

There is a possibility that 5G could overlap on the new Wi-Fi 6E spectrum through mobile network carriers. This could in turn lead to interference issues, but it’s a bit early to say. If you’re wondering whether 5G will become dominant and replace Wi-Fi altogether, then we think probably not. There doesn’t need to be a winner or a loser when it comes to Wi-Fi 6E vs 5G – They dont necessarily have to be in competition with one another. The spacious nature of this spectrum means there should be enough room for both. 

 

6GHz Wi-Fi is certainly being revered by the tech industry, so we’re pretty hopeful that Wi-Fi will be the main beneficiary of the newly opened 6GHz spectrum. 

 

What is Wi-Fi 7 and When Will We Have It? 

Things move fast in the world of tech. We might only just be connecting to Wi-Fi 6, yet Wi-Fi 7 is already hovering in the background ready to arrive on the scene and bring us even more improvements. Before we’ve even had a chance to enjoy the most recent ones! 

It’s only fairly recently that the Wi-Fi Alliance announced the certification for Wi-Fi 6E (or Wi-Fi 6 Extended). This joyful addition to the spectrum for unlicensed Wi-Fi was the first in 20 years! Yet even with this extra ability to give the 6 GHz band an advantage, the next generation of wireless technology is still on the way. And with the promise of even higher data rates and lower latency that the current offering!

Wi-Fi 7 (or 802.11be to be technically correct), in comparison to Wi-Fi 6, will:

  • Use multi-band/ multi-channel aggregation and operation 
  • Deliver higher spectrum and power efficiency
  • Have better interference mitigations
  • Offer higher capacity density 
  • Have higher cost efficiency. 

As a result of the projected ability for it to support up to 30Gbps throughout, this seventh generation of Wi-Fi is also being referred to as Wi-Fi Extremely High Throughput. It will be approximately 3 times faster than Wi-Fi 6.  

What are the enhancements of Wi-Fi 7 over Wi-Fi 6? 

Wi-Fi 7 is purported to offer a number of better features. Some of the direct improvements over it’s Wi-Fi 6 precedent are:

  • The support of 320 MHz transmissions. In comparison to 802.11ax, this is double the 160 MHz it currently supports
  • The use of higher modulation orders, optionally supporting 4096-QAM. This is a significant increase from 802.11ax ‘s 1024-QAM 
  • The allocation of multiple resource units, such as groups of OFMDA tones

Due to the last feature, Wi-Fi 7 will be the perfect option for enterprise spaces due to having more efficient spectrum utilisation across multiple resource units. 

Organisations requiring the addition of AR/VR, Iot and IIoT as part of their workflow will find Wi-Fi 7 a useful tool in their digital transformations. 

Applications that require deterministic latency (an upper limit to how long a signal takes to get from point A to point B), high reliability and quality of service will find that Wi-Fi 7 has the potential to support them. 

And it’s not just the workplace that Wi-Fi 7 will prove beneficial. Due to Wi-Fi 7 being optimised for video, those who enjoy gaming and streaming at home will also enjoy the improvements. Any smart-home devices and services will likely feel enhanced with the new Wi-Fi standard. 

The popularity of video is huge, and will only continue to grow. It is expected to become the dominant form of internet traffic (if it isn’t already). Cisco’s Visual Networking Index expected video traffic on a global IP scale would be 82% of all IP traffic by this year for both business and consumer. 

When can we expect to get Wi-Fi 7?

The 802.11be amendment is expected to be published by IEEE in 2024. Commercial deployment of Wi-Fi 7 will likely be around the same time. 

Following that, the Wi-Fi Alliance will then release the Wi-Fi 7 certification programme, just like with Wi-Fi 6 and 6E, which will ensure security standards and interoperability. 

But in the interim, we’ll be enjoying what Wi-Fi 6 and Wi-Fi 6E has to offer! You can read more about this Wi-Fi standard in our previous blog post, if you’re wondering what all the fuss is about.

Is Wi-Fi 6 Worth It?

In our last blog we spoke about your home Wi-Fi network and how your router could be the root cause of all your Wi-Fi woes.

We also touched on the Wi-Fi standards and what they have recently been re-branded as – With the latest being wi-Fi 6 (and Wi-Fi 6E).

And that’s exactly what we’re going to talk about this week – Wi-Fi 6. If you’re wondering what all the all the fuss is about when it comes to Wi-Fi 6 and whether it’s really worth it then read on.

Perhaps you are questioning what the differences are and whether it’s actually worth making hardware device changes. Or maybe you’ve got a cool new gadget for Christmas, but you’re wondering if it’s lack of Wi-Fi 6 compatibility will hold you back. This is the blog for you!

The next generation of wireless standard is here (actually, it’s been here since the end of 2019). Wi-Fi 6, or 802.11ax if you want it’s technical name, has the following main differences:

  • It’s faster
  • It provides better performance in congested areas (think anything from your own device-packed home, to stadiums)

We’re casually calling it Wi-Fi 6 but it actually has a more code-like name – Just to make everyone feel like they need a degree in wireless networks to know what we’re talking about.

Thankfully the Wi-Fi Alliance came to their senses and came up with some more friendly, easily accessible names for those of you that don’t consider yourselves Wi-Fi experts!

What are the Wi-Fi Version Numbers?

The new Wi-Fi version numbers are much more user friendly, but for the fellow geeks among us, here are what the new version numbers correspond to, plus (whilst not being officially branded) what all of the old versions would have been.

  • Wi-Fi 1 – 802.11b (released in 1999)
  • Wi-Fi 2 – 802.11a (also released in 1999)
  • Wi-Fi 3 – 802.11g (released in 2003)
  • Wi-Fi 4 – 802.11n (released in 2009)
  • Wi-Fi 5 – 802.11ac (released in 2014)
  • Wi-Fi 6 – 802.11ax (released in 2019)

Got some new tech for Christmas – Perhaps a new phone, tablet or laptop? You may see these newer version numbers on the packaging, letting you know what networks they are compatible with.

You might also see them appear in software when connecting your smartphone, tablet or laptop. This information lets you know which Wi-Fi networks are newer and faster.

Whilst this is what the Wi-Fi Alliance said they wanted to be seeing across networks, it’s worth noting that it isn’t actually mandatory for manufacturers to label their products with Wi-Fi 6 instead of 802.11ax.

But we are really hoping that most of them will so that even those that aren’t super tech-savvy will be able to make informed decisions when it comes to compatibility.

We’d also like to see products re-named from 802.11ac to Wi-Fi 5, but we won’t hold our breath.

But back to our original question – Is Wi-F 6 actually worth it? Let’s take a look at some of the differences we should be able to see when it comes to Wi-Fi 6.

Wi-Fi That’s Faster

As with most technological advances, the latest development in Wi-Fi standard is faster in terms of data transfer speeds. In comparison to Wi-Fi 5, a Wi-Fi 6 router would provide one device with up to 40% higher speeds.

What Makes Wi-Fi 6 Faster?

The reason Wi-Fi 6 can achieve such faster speeds is due to more efficient data coding which thus results in higher throughput. Basically, the radio waves are packed with more data. With each Wi-Fi standard, the ability for the chips to encode and decode the data gets more powerful, hence why Wi-Fi 6 is faster than Wi-Fi 5, and can handle extra work.

You may be aware that we have 2 frequencies used for networks – 5GHz and 2.4GHz. 5GHz is more commonly used as it is subject to less interference, however 2.4GHz is still a good option for being able to penetrate solid objects. Wi-Fi 6, the new standard, even increases speeds on these 2.4GHz networks.

Wi-Fi 6 That Improves the Battery Life on a Device

Many Wi-Fi 6 enabled devices will have a new ‘target wake time’ feature. This means that an access point can define a specific set of times when devices connected to the internet need to have access to the wireless network. This new efficiency should mean that your Wi-Fi enables deviced should have a longer battery life.

Let’s take your smartphone, for example. When the AP is talking to your phone, it can tell it when to put it’s Wi-Fi radio to sleep and when to wake it up to receive the next transmission. Because your device can spend more time in sleep mode, you should find your battery lasts longer.

It also means that devices that connect via Wi-Fi with lower power can benefit from longer battery life.

Wi-Fi That Performs Better in Crowded Areas

We know it’s a been a bit hit and miss lately when it comes to travel and events. But try and remember a time when you were waiting at an airport, trying to get online. Or maybe at a hotel or live event like in a stadium. When an area like these are congested with devices, you can suffer with slow Wi-Fi or even struggle to connect in the first place.

Wi-Fi 6 tackles just this problem. With new technology, superior to previous Wi-Fi standards, it’s purported that Wi-Fi 6 will improve the average speed of each user by at least 4 times. Even in crowded areas with lots of devices!

This isn’t just something that will benefit you when out in public places – It could be a huge help in your home as well. If you have a large family, all with multiple devices connected to Wi-Fi, then this could be just the solution to stop the slow-down. Think remote working and online learning – Multiple Zooms all at the same time! It should also help anyone who lives in a more densely populated place, like a block of flats.

How Does Wi-Fi 6 Tackle Congestion from Multiple Devices?

Talk of further lockdowns, more remote working and back to online learning for school children could be enough to spur you into searching out Wi-Fi 6 compatible hardware.

Just knowing that a Wi-Fi 6 device connected to a Wi-Fi 6 access point will work better may well be enough for you! But there are various features that help Wi-Fi 6 better tackle the problem of heavily crowded networks if you want to understand more of the technical side.

For those who want all the geeky details, here’s what’s going on to make Wi-Fi 6 better for networks with multiple or many devices.

Wi-Fi 6 technology is able to create a large number of sub-channels within one wireless channel. Date intended for each individual device can be carried by each sub-channel. This technology is called Orthogonal Frequency Division Multiple Access (OFDMA). Essentially this means that a Wi-Fi 6 enabled access point can talk to more devices at once.

Wi-Fi 6 also has improved MultipleIn/Multiple Out (MIMO). Again, this lets the access point talk to multiple devices at once through multiple antennas. The difference between this and Wi-Fi 5, is that while the latter enabled an access point to talk to multiple devices at the same time, it couldn’t allow the devices to respond at the same time, thus slowing things down. The new improved MIMO on Wi-Fi 6 is a multi-user version (MU-MIMO) which enables devices to respond to the access point at the same time.

Let’s look at another potential scenario. Wireless access points that are locating close to one another may transmit on the same channel. This means that the radio needs to listen and wait for a clear signal before it can reply. Wi-Fi 6 uses spatial frequency re-use which allows you to configure Wi-Fi 6 wireless access points with different Basic Service Set (BSS) colours, which consists of a number between 0 and 7. The device can then determine whether a particular channel has a weaker signal, and thus ignore it and transmit without waiting. This is another way in which Wi-Fi 6 will improve wireless performance in congested areas.

These are just a couple of the improvements to be seen from the new Wi-Fi 6 standard. There are many more, smaller enhancements which will improve the speed and performance with Wi-Fi 6.

How Do I Know If Something has Wi-Fi 6 Compatibility?

Luckily, thanks to this handy article, you’re now familiar with all the technical names of the different Wi-Fi standards, so you’ll know exactly what to look for. Right? Don’t panic! We’re only kidding. Thanks to the new versions, it’ll be easy for you to find devices that are certified Wi-Fi 6 (rather than hunting around for 802.11ax!). Device manufacturers are able to say whether their product is Wi-Fi 6 or Wi-Fi 5.

You may also start to see a logo saying ‘Wi-Fi 6 Certified’ on relevant devices. This means that the product has gone through the Wi-Fi Alliance’s certification process. The old Wi-Fi Certified logo simply told you it was Wi-Fi Certified, rather than what generation of Wi-Fi a product was. The new logo will make it clear if it is Wi-Fi 6. So there will be no need for trawling through product specifications!

When Can I Get Wi-Fi 6 Enabled Devices?

Wi-Fi 6 is here!

The new Wi-Fi 6 standard was finalised in 2019, with hardware being released in the latter part of the same year and into 2020. So you should be seeing Wi-Fi 6 enabled products in the market now.

It shouldn’t be something you need to put too much thought into – As new routers, smartphones, tablets and laptops are released into the market, they will just start to come with this new Wi-Fi 6 technology.

 

You mentioned Wi-Fi 6E earlier – what’s that?

As we well know, technology is constantly moving forward to be better, faster, more reliable.

Just as Wi-Fi 6 has superseded Wi-Fi 5, Wi-Fi 6E is just the next upcoming Wi-Fi standard. An extension of Wi-Fi 6, Wi-Fi 6E enables the operation of features in the unlicensed 6 GHz band. This is in addition to the 2.4 GHz and 5 GHz bands which are currently supported.

 

So is Wi-Fi 6 really worth it?

We’ll let you make your own minds up.

We think Wi-Fi 6 will certainly bring stronger, faster Wi-Fi, with unrivalled solutions for busy, congested networks.

With technology, it’s nigh on impossible to always have the top-of-the-range device for very long before another one is launched. (Hello, Wi-Fi 6E!)

With Wi-Fi standards, you know that the latest one will offer faster speeds and stronger connections. But that’s not to say that the standard before can’t still offer useful features.

As more Wi-Fi 6 devices are released on the market, we can slowly replace the wireless devices we own. But we wouldn’t necessarily recommend that you rush out and replace all your hardware with Wi-Fi 6 enabled alternatives. Wi-Fi 5 will function just fine for the time being.

It’s worth remembering that to benefit from the improvements on the new Wi-Fi 6 standard, you need both the sender and receiver devices to support this latest generation of Wi-Fi 6. Whatever the connection, it will only operate in the mode that your device supports.

For example, you may have a Wi-Fi 6 enabled router, a Wi-Fi 6 enabled smartphone, but a laptop that only supports Wi-Fi 5. You’ll see the advantages of Wi-Fi 6 on your smartphone, but the laptop will only work at Wi-Fi 5 capacity.

Did you receive any Wi-Fi 6 enable devices for Christmas?

Wi-Fi Woes at Home: Could it be your Router?

Wi-Fi is one of those things that we don’t tend to take much notice of – Until it breaks.

Just like when a power-cut stops our electric, or cloudy water comes out the tap – When our Wi-Fi goes down, we notice! Slow or faulty internet might be one of the most frustrating things of all time. There’s nothing quite as annoying – Whether you’re in the middle of a Netflix binge or an important Zoom meeting.

The last time you thought about your internet probably coincided with one of those moments. Maybe it was back when the first lockdown came in and you were suddenly thrust into a world of remote working. Or when schools were closed and you abruptly and unexpectedly became a teacher and had to navigate an online classroom with your children.

Never have we had to rely on our home Wi-Fi networks like we have the last 2 years. The world still looks like a bit of a scary place right now – Don’t let your home network be an added source of stress.

We might have electricians to sort out our electrics and plumbers to sort out our plumbing – But who sorts out our Wi-Fi in our homes? Here at Geekabit, our Wi-Fi experts are here to help you. Most people get sent a router from their broaband provider, plug it in and hope for the best (no judgement here!). But what about when that’s not enough to provide you with a reliable home Wi-Fi network?

We’re going to take you through the basics of Wi-Fi so you can make sure your router is providing your home with the network you need.

So let’s start from the beginning.

Wi-Fi Standards – What are they?

What we understand as Wi-Fi was only named that after the ability for us to connect to other computers and the internet has long been around.

It started out as 802.11 (The first Wi-Fi standard). Not quite the description you’d expect for such a transformative piece of technology! And certainly not a word that lends itself to the general population of internet users.

So what came next? Along came 802.11b (there was a 802.11a but we won’t go into that). Catchy huh! This was the first major revision of 802.11 which came in 1999 alongside the name Wi-Fi. These numbered standards come from the Wi-Fi Alliance – A global group of technology companies who ensure that anything labelled as a Wi-Fi product has been adequately tested as such.

This means that if you buy a product with Wi-Fi, such as a laptop, and you have a functioning Wi-Fi network, then the 2 will be able to connect. That’s the rule!

In the 20 years since we’ve had more revisions and improvements, taking us through more standards: 802.11b, 802.11g, 802.11n, 802.11ac and 802.11ax. They don’t exactly roll off your tongue do they?

What they have done however, is:

  • Increase the maximum speed
  • Minimise congestion in built-up areas
  • Improve connections when multiple users on different devices are accessing the same network

Wi-Fi Standards and Compatibility

What these complicated names also mean is that even the most technological savvy people don’t have much knowledge about how their home Wi-Fi network actually works. Again no judgement – It’s not your fault!

Without Googling or hunting down hardware – Do you know which of the standards above your home network supports? How about your laptop, tablet or smartphone?

Without also knowing what standard your router runs on, how could you know whether the standard your devices are running on is compatible?

Backward compatibility has its costs. If you have a new router running on the latest standard of 802.11ax, but your laptop is 20 years old with 802.11b compatibility, the laptop can only go as fast as the old standard. It can’t access the benefits of the newer standard that the router supports. Unfortunately, having this laptop connected to the network can cause the whole Wi-Fi system down to its level. For this reason, the default settings on many networks automatically kick off any older devices to stop problems arising for other users.

For this reason, it’s wise to make sure that the Wi-Fi standard that is supported, is common amongst your router and the devices connected to it.

The re-branding of Wi-Fi Standards

Thankfully assessing compatibility will become a lot easier now that the Wi-Fi Alliance has rebranded the Wi-Fi standards.

You might be surprised to find that you are already acquainted with the latest Wi-Fi standards – Wi-Fi 6 and Wi-Fi 6E.

With the branding of these newest standards, comes the relabelling of the older ones. They become:

  • 11 – Wi-Fi 1
  • 11b – Wi-Fi 2
  • 11g – Wi-Fi 3
  • 11n – Wi-Fi 4
  • 11ac – Wi-Fi 5
  • 11ax – Wi-Fi 6

The ones we need to know about and look out for are Wi-Fi 5 and Wi-Fi 6. Simply put – Your home Wi-Fi network will run better if use routers and devices that support the latest Wi-Fi standard.

We mentioned Wi-Fi 6E. This is the latest Wi-Fi standard which arrived this year. This standard, for the first time since the beginning of Wi-Fi, it uses 6GHz. This band is a new section of the radio spectrum which hasn’t been used by Wi-Fi before. This new standard will minimise interference with other networks and help achieve speeds we haven’t seen before.

Where do routers fit into all of this?

As you have seen, there has been a steady stream of Wi-Fi standards since the internet first emerged.

As with most things technological, improvements are constantly being made. We live in a world where there is always the newest device – Faster, more compact, better this, better that. Always competing with what came before it.

You probably replace your phone quite regularly, especially if you are on a contract or plan. Getting an upgrade is the norm! You may also do the same with laptops and tablets, TV’s and other smart devices around the home.

But do you do the same with your router?

Have you ever stopped to think that the router you’ve had since you moved in is stopping all your new devices from working to their optimum ability?

Your smartphone might support Wi-Fi 6, but that’s no good if your router is ten years old! Could your router be the cause of your home Wi-Fi problems? Slow internet speeds, bottlenecks, buffering?

What’s the point in spending thousands of pounds on the latest phone, tablet, laptop, smart TV etc if you haven’t invested in a router – And instead connect all your top-of-the-range devices to a box you got free from your provider when you moved in nearly a decade ago.

It seems pretty obvious now we’ve pointed it out, but so many of us do this very thing. We’re not trying to shame you – the majority of people don’t consider that their Wi-Fi woes could be a result of an older router.

‘I think my router could be causing my Wi-Fi problems – What do I do next?’

Assuming that the connection coming into your home is not ‘dodgy’ then a new router could be the answer to your Wi-Fi problems.

The majority of households have a pretty straightforward set of needs when it comes to Wi-Fi coverage. A simple change, such as a pair of Wi-Fi 6 ‘mesh routers’, could be just what you need to to provide a bit of extra bandwidth and even cover those annoying ‘black spots’. Esepcailly if one of those happens to be out in the garden where you desperately tried to catch a bit of sun whilst working from home during the summer!

For the cost of skipping the latest smartphone upgrade, you could fix the Wi-Fi problems for your entire household.

No more buffering mid Netflix binge. No more dropping out of video calls and online meetings. No more being ‘that colleague or friend’ that causes the tech problems.

This one small switch could be far more beneficial that upgrading your devices or doubling your monthly BT bill.

What if replacing your router could give all your Wi-Fi devices a new lease of life in your home?

 

Do I Need a Wi-Fi 6 Router?

Don’t suffer with the buffer! If you’re finding that your Netflix binge is being interrupted by buffering, or your Zoom calls keep freezing or pixelating then it’s a good idea to make sure that your router isn’t the culprit.

If you’re looking for fast, reliable broadband, then Wi-Fi 6 could be just what you’re looking for. Last time we blogged about the improvements from Wi-Fi 5 that Wi-Fi 6 will be bringing. If that hooks you in then read on and see whether a Wi-Fi 6 router might end up being a great investment for your business or household.

Wi-Fi 6 is specifically designed to improve the performance of your home network and increase network capacity. This latest generation of Wi-Fi standard will offer your home faster Wi-Fi speeds and a more reliable connection. What does this mean in real times? It means buffer-free streaming on Netflix (and other platforms) and quicker downloads – Even if your house is device heavy, it won’t slow down your internet.

More and more internet devices are Wi-Fi 6 ready, but will only work to their optimum if there is also a Wi-Fi 6 router in place. (Likewise, a Wi-Fi 6 router will only offer Wi-Fi 6 improvements for devices enabled with Wi-Fi 6 technology).

We thought we would share some of the reasons why you might want to consider a Wi-Fi 6 router next time you’re in the market for one (or even if you’re not!. )

My household has multiple devices – What will Wi-Fi 6 provide me in comparison to Wi-Fi 5?

Wi-Fi 6 will provide you with the highest level of performance, even in a device-heavy household.

Wi-Fi 5 provided us with great technology – Wi-Fi 6 is an extension of that. Whilst Wi-Fi 5 brought us gigabit speeds, it begins to fall short in homes where there are more and more devices being added. How many devices do you have in your home that connect to the Wi-Fi? Count them and we think you’ll be surprised! And this is only going to increase over time. Wi-Fi 6 helps with this because it uses OFDMA (orthogonal frequency division multiple access). This key feature means that it can increase your overall network efficiency by allowing several devices to connect to your Wi-Fi with various bandwidths.

What real-world speeds and range will Wi-Fi 6 provide?

Wi-Fi 6 will deliver the fastest real-world speeds.

Wi-Fi data travels on component streams on each of the frequency bands 2.4 GHz and 5GHz. Wi-Fi 5 and Wi-Fi 6 can carry the highest amount of streams, which allows for gigabit Wi-Fi speeds. Where Wi-Fi 6 goes further is that it increases the number of streams to 12 – A new high across the 2.4 and 5GHz bands. In comparison, Wi-Fi 5 only has a limit of 8 in a dual band configuration.

How do these streams affect your Wi-Fi? Not only does this increase in streams mean that you have access to a higher connection speed, it also means that your devices can communicate with your router via more paths. Compared to Wi-Fi 5 enabled devices, Wi-Fi 6 show an 40% increase in speed.

How is Wi-Fi 6 designed for the ‘Smart Home’?

Our homes are now full of smart devices. We can control the heating and the lights with the tap of a button on our phones. We can ask the postman to leave the parcel by the gate via our video doorbell. We turn music on via Alexa and we add to our shopping list by shouting Hey Google. We have smart TV’s as well as numerous laptops, tablets and smartphones all vying for a connection to the Wi-Fi. That’s a lot of devices. In fact, the average number of devices in the home has gone from 10 up to as many as 50. All of these put a load on your network.

Where does Wi-Fi 6 come in? Well, it’s been specifically designed to handle this demand on your Wi-Fi through the increase in devices – Without negatively impacting your internet speeds.

How will this affect your home? This improvement in internet speed will provide more reliability – Vital if you’re depending on it for your lights, thermostat and other IoT devices. The last thing you want with all these devices running is interrupted connectivity. Thankfully, Wi-Fi 6 will help with that

How will Wi-Fi 6 help with video streaming?

A Wi-Fi 6 router would be ideal for 4K/8K UHD streaming.

If you’ve tried to stream 4K or 8K video, then you’ll know it requires a constant high-speed connection. In busy, device-heavy households where everyone is trying to stream high-definition video you’re likely to start seeing buffering – It’s a big load on the network.

Wi-Fi 6 routers could help with all that thought. Annoying buffering will be a thing of the past due to a Wi-Fi 6 router’s ultra-fast processors, increased number of radio streams and increased memory.

You should find that Wi-Fi 6 routers will make streaming of HD video across multiple devices a lot better than older Wi-Fi technology.

Are Wi-Fi 6 products available now?

Yes – They’re already here! Future upgrades to smartphones, tablets and laptops will see the rise of Wi-Fi 6 enabled technology, so getting a Wi-Fi 6 router will mean you’re ready to benefit from all the improvements that Wi-Fi 6 has to offer – Like faster Wi-Fi speeds!

The great thing is that WI-Fi 6 routers will also work for Wi-Fi 5 devices (without the improvements) so it’s a great crossover for whilst you’re upgrading devices.

The Wi-Fi 6 portfolio of products is only going to get bigger, so consider whether a switch to a Wi-Fi 6 router would be a worthwhile investment for your home.

 

What’s Different About Wi-Fi 6?

Wondering what all the fuss is about when it comes to Wi-Fi 6? If you’re questioning what the differences are and whether it’s worth making hardware device changes, then read on.

The next generation of wireless standard is here (actually, it’s been here since the end of 2019). Wi-Fi 6, or 802.11ax has the following main differences:

  • It’s faster
  • It provides better performance in congested areas (think anything from your own device-packed home, to stadiums)

We know it informally as Wi-Fi 6 – Wi-Fi versions have now been assigned simple numbers to replace the more complicated code-like names that we saw before.

What are the Wi-Fi Version Numbers?

The new Wi-Fi version numbers are much more user friendly, but for the fellow geeks among us, here are what the new version numbers correspond to, plus (whilst not being officially branded) what all of the old versions would have been.

Wi-Fi 4 – 802.11n (released in 2009)

Wi-Fi 5 – 802.11ac (released in 2014)

Wi-Fi 6 – 802.11ax (released in 2019)

You might start to see these newer version numbers appear in software when connecting your smartphone, tablet or laptop, to enable you to see which Wi-Fi networks are newer and faster. This is what the Wi-Fi Alliance announced that they would like to be seeing across networks. It’s worth noting that it isn’t mandatory for manufacturers to label their products with Wi-Fi 6 instead of 802.11ax, but we’re hopeful that most will. Re-naming products from 802.11ac to Wi-Fi 5 might be another matter though!

It also means that devices that connect via Wi-Fi with lower power can benefit from longer battery life.

Wi-Fi That Performs Better in Crowded Areas

We know there hasn’t been much opportunity for it as late, but picture trying to get online at an airport, hotel or live event at a stadium. When an area is as congested with devices as these, you can suffer with slow Wi-Fi and even struggle to connect.

Wi-Fi 6 tackles just this problem. With new technology, superior to previous Wi-Fi standards, it’s purported that Wi-Fi 6 will improve the average speed of each user by at least 4 times. Even in crowded areas with lots of devices.

The new Wi-Fi 6 standard was finalised in 2019, with hardware being released in the latter part of the same year and into 2020. So you should be seeing Wi-Fi 6 enabled products in the market now. It’s shouldn’t be something you need to put too much thought into – As new routers, smartphones, tables and laptops are released into the market, they will just start to come with this new Wi-Fi 6 technology.

It’s worth remembering that to benefit from the improvements on the new Wi-Fi 6 standard, you need both the sender and receiver devices to support this latest generation of Wi-Fi 6. Whatever the connection, it will only operate in the mode that your device supports. For example, you may have a Wi-Fi 6 enabled router, a Wi-Fi 6 enabled smartphone, but a laptop that only supports Wi-Fi 5. You’ll see the advantages of Wi-Fi 6 on your smartphone, but the laptop will only work at Wi-Fi 5 capacity.
