4G 4G LTE 5G Wireless Network
What’s the difference between LTE and 5G?

There has been much hype surrounding 5G, relentlessly for years. Now as part of a global rollout we see 5G available in most major cities as well as some towns and more rural areas. Soon enough, we’ll be using 5G just as we use 4G as the standard.

But 5G is still new to the wireless scene. And for some, the question is – Do we really need 5G when we’ve got LTE?

Many of us are still depending on long-term evolution technology. Indeed, there are only a few areas in the UK that don’t have any LTE presence.

What is LTE?

LTE was first launched back in 2009, and whilst it took a number of years to become part of our national connectivity fabric, it is still now a standard for wireless communications.

The reason for its staying power is down to its reliability and stability – Leading many wireless users to wonder if they even need to move over to 5G.

What is the difference between 4G LTE and 5G?

It was necessary to identify LTE as an element of the 4G standard as many telecoms companies weren’t actually able to provide 4G speeds due to infrastructure. The regulator ITU-R (International Telegraph Union Radiocommunication) established LTE as a standard to show the progress being made towards true 4G.

The download/upload speeds of a particular standard can be different in theory and in practise. Whilst in theory, 4G LTE can achieve data transfer speeds of up to 150Mbps for downloading content and 50Mbps for upload speeds, in practise is is more likely to be 20Mbps and 10Mbps respectively.

These figures will vary depending on:

  • Location
  • Network deployment
  • Traffic

How does 5G compare to 4G LTE in terms of download speeds?

5G connectivity offers theoretical download speeds of up to 10Gbps. A pretty staggering difference! Of course in practise, it may not reach this, but even real-world examples seem to still be dwarfing the speeds of 4G LTE.

Why does 5G reach higher speeds?

5G uses a different spectrum to 4G – Called mmWave which are high-frequency bands. The higher speeds are mostly reached because these high frequency bands support more bandwidth than the ones that LTE uses. This means that more data can be transferred at once.

5G can also use frequencies above low-band but lower than 6GHz. Despite these not supporting the highest possible speeds, they will still outclass 4G LTE. It’s worth noting that 5G coverage could be further expanded by using connectivity below 6GHz, especially as walls and surfaces can block mmWave frequencies.

Basically, 5G uses a different spectrum to 4G LTE and thus:

  • Delivers stronger, faster connections
  • Has a higher capacity for traffic
  • Has low latency (1ms)

Sounds too good to be true doesn’t it! It’s worth remembering that the rollout of 5G is still in its infancy, and therefore coverage is still limited. Before the big networks like EE, Three and Vodafone can deliver the top scope of what 5G has to offer, more work needs to be done.

So should we be choosing LTE or 5G?

As with most techy things, there are lots of factors, such as:

  • Your budget
  • Where you’re based
  • What your connectivity needs are – Personal or business

The more countries adopt and expand their 5G infrastructure, the more 5G-friendly hardware we will start to see. The best way to know whether to choose LTE or 5G is seeing what is on the market and whether it meets your needs.

You may find that some of the 5G devices available don’t have a 4G alternative. You may also find that they are rather on the pricey side! So definitely shop around.

Of course, the more 5G devices we see on the market, the more we will see the prices start to come down. So the time for adopting 5G over LTE may not be quite yet. Patience could also serve you more of the promises 5G has to offer – The more the 5G coverage continues to expand, the higher the speeds and the more consistent the connection to mmWave networks.

Since 2019, we’ve seen prices start to come down as competition in the market starts to heat up, but 5G is still costly. If you have a big budget then you could just go for it now, but we feel like the overall coverage, packages and prices will continue to rapidly improve. We’re inclined to hold out a bit longer and stick to LTE for the time being.

What about 5G for business?

If your business relies on heavily on connected sensors and other similar IoT networks then 5G may be the network you’ve been waiting for. The bandwidth and low latency that 5G could bring to your business cannot be easily ignored.

Think driverless cars navigation and smart sensors – 5G could well be the communications technology that will enable some great and creative deployments.

What are the health concerns associated with 5G?

With 5G comes questions about whether it could harm our health. Do you remember when mobile phones were beginning to emerge into mainstream use and there was much anxiety about what the radio waves were doing to our health? Mobile telephone has never been without concerns, but 5G seems to have evoked more than its fair share of health worries.

The installation of 5G masts have been banned in multiple UK locations. And it’s not just parts of the UK that are opposed to 5G – Back in 2017 180 scientists from 36 different countries made a public appea to the EU to pause their plans of 5G expansion whilst investigations were carried out looking at the long-term effects on human health.

Whilst both 4G and 5G use radio waves, 5G uses higher frequency waves. It’s these high frequency waves that provide better network capacity and speed.

Studies that have looked into any potential health risks from 5G haven’t seemed to identify any specific danger from 5G.

What is the future for LTE and 5G?

With the rise of 5G comes potentially society-changing connectivity – Like self-driving cars.

But technological advances can be slow if not steady. Whilst there is definitely potential for 5G to take over, it could take considerable time for 5G-enabled devices to really take hold of the market. Even from the likes of Apple!

There is still space for 4G LTE in our networks, and whilst it may be 5G’s predecessor, it’s not going anywhere just yet.

Research from Ericsson suggests that the dominant cellular network technology seen in most regions globally is still 4G LTE. 78% of mobile subscriptions in Western Europe in fact! Just because the 5G rollout is well underway, doesn’t mean that everyone will immediately jump ship and drop 4G LTE. It’s expected that 4G LTE will still be the dominant network even 5 years from now.

By 2026 Western Europe is predicted to be using 5G in 69% of all mobile subscriptions. However, Ericssons findings suggest that even as 5G usage surges, 4G LTE won’t automatically decline. It’s even predicted that 4G LTE availability will grow, with global coverage of 95% by 2026, with 5G only seeing 60% in those 5 years.

There is no denying that 5G is the future for telecoms. But by the time we are all accustomed to using it, 6G might well be on the way! Despite 5G becoming more prevalent as time passes, we still think there’s no need to be abandoning 4G just yet.

Business Wi-Fi DFS Channels Home Network Home WI-Fi Wi-Fi
Can I Use DFS Channels on my Wi-Fi Network?

We’ve recently started to see a rise in customers using DFS channels when operating their Wi-Fi networks, so thought we would write an article all about it in case it’s also helpful for your own network.

What is DFS?

DFS is Dynamic Frequency Selection and is a type of Wi-Fi function that allows WLANs to use 5GHz frequencies (which are reserved for radar, for example, the military, satellite or weather).

What is the benefit of using DFS channels for Wi-Fi?

We’ve written before about how you can improve your Wi-Fi and prevent interference by utilising different channels. The main benefit of using DFS channels taps into this. You can increase the number of available Wi-Fi channels by using DFS channels to use these less-used frequencies.

How can I utilise DFS channels on my Wi-Fi network?

The first thing you need to do if you are wanting to use DFS channels, is to check that your wireless access points and wireless clients support the necessary functionality.

The 5GHz spectrum in the UK is broken into 3 different bands and runs from 5150MHz (5.15GHz) to 5850MHz (5.85GHz). The bands are as follows:

Band A

  • Channels 36 – 64
  • This is used only for Indoor wireless
  • Does not require a license

Band B

  • Channels 100 – 140
  • Can be used both inside and outside
  • Does not require a license
  • Hardware must conform to DFS standards and be DFS enabled

Band C

  • Channels 149 – 161
  • Can only be used outside
  • Requires a license from Ofcom
  • Hardware must conform to DFS standards and be DFS enabled

 

 

Checking DFS Channel Availability

When you enable DFS, the Wi-Fi access points will need to verify that any radar in the proximity is not using DFS frequencies. This is a process called Channel Availability Check and is carried out during the boot process of an AP as well as during normal operations.

Should an AP detect that a local radar is using a certain DFS channel, it will automatically exclude that channel for this list of available ones. This will last for 30 minutes after which time the AP will check again to see if the channel can be used for Wi-Fi transmissions. You’ll be pleased to know that this exclusion of unavailable channels has very little impact on Wi-Fi clients.

DFS channels are not immediately available when an AP boots. This is because the Channel Availability Check can take anywhere between 1 minute and 10 minutes during the boot process.

 

What happens if an AP detects radar use during normal operations?

We know what you’re thinking – What happens if the AP was to detect during normal operations that the channel you are using becomes in use by a proximal radar?

If this happens, then the AP may communicate to its Wi-Fi clients to stop transmitting on that particular channel. The AP will then switch to a different, available DFS channel within the Channel Move Time. This is usually about 10 seconds.

Unlike above, this could affect Wi-Fi clients. An AP won’t always announce that it is changing channels to connected devices. When it switches to the available channel, it will cause those Wi-Fi clients to disconnect from the network and then re-connect to the new channel.

 

Are DFS channels right for my Wi-Fi network?

If you are considering using DFS channels for your Wi-Fi, you need to think carefully about whether business critical operations rely on that connection. If the answer is yes, you might want to avoid enabling DFS and not risk the disconnections caused by DFS frequencies.

Can My Christmas Lights Affect My Wi-Fi?

The 1st December means we can officially start talking about Christmas! December 1st also happens to be National Christmas Lights Day which coincides with many people choosing to put up their Christmas tree (if they haven’t already done so!).

So you fight the knot of Christmas lights that you’ve fetched from the loft, stick on the ‘Christmas is Coming’ playlist on Spotify (thank us later) and flick the switch for the moment of truth – And Bublé buffers as soon as the tree lights up. What’s going on?

There tends to be articles that circulate this time of year about how Christmas lights could be interfering with your Wi-Fi. But is it really the Christmas tree lights that’s causing Mariah to falter on that high note?

If you haven’t put your tree up yet, and you’re a bit of a Wi-Fi geek (like us) then why not do a little experiment to see exactly how much your Christmas tree lights affect your Wi-Fi? Test your internet and download speeds before and after putting up the Christmas tree with the lights turned on.

 

Will my Wi-Fi be affected by my Christmas tree lights?

Let’s face it, no one wants to choose between functioning Wi-Fi and a Christmassy home. People need that bit of festive cheer more than ever this year, but we also need to know we can rely on our Wi-Fi to keep us connected with our loved ones over the festive period (and stream all the Christmas movies…).

There are potential Wi-Fi issues that can arise with Christmas tree lights so we thought it was worth running through a few do’s and don’ts to help avoid any internet interference from happening in your home. But first – what’s the reason Christmas lights could cause internet issues?

 

How can Christmas tree lights interfere with Wi-FI?

Christmas lights emit a very weak electromagnetic field which can theoretically interfere with the radio waves being transmitted from your router, thus affecting your Wi-Fi speed. If the lights were to transmit electromagnetic radiation at or around the same frequency, then it is possible that they could slow down your Wi-Fi.

Between the LED or lamp being completely on or off, it can exhibit negative resistance which in turn causes radio energy. This happens less with modern day lights than older ones though (see below for more info on this).

Is your tree lit up to give a soft glow, or does it look like something fresh out of Blackpool illuminations? The more lights you have, the stronger the electromagnetic field will be.

And the closer the router is to the lights, the higher the chance of interference.

So what can you do to ensure that your beautifully decorated Christmas tree doesn’t knock off your Netflix binge of Christmas movies?

 

Geekabit’s Top Tips to Prevent Wi-Fi Interference this Festive Season

 

Rule #1 – Don’t place things on top of your router

Just don’t do it. This doesn’t just go for decorations, but in general. We can’t stress this enough – Don’t put anything on top of your router.

This includes Christmas lights – No matter how festive they look! Don’t put Christmas lights or anything else directly on top of, or too close to, your router.

Whilst it has been reported that routers that were placed too close to Christmas tree lights could be negatively affected by signal interference, if they’re not directly next to each other or on top of each other, it should be fine.

 

Rule #2 – Use a main plug socket

We get it – Christmas is one of those times of year when you’re struggling for socket space and digging out all the extension cables you can find to be able to power Christmas tree lights and all kinds of other lit decorations.

But don’t be tempted to unplug the router and plug it into the extension cable. It will work a lot better, and faster, if it’s plugged into a main socket.

 

Rule #3 – The more modern the lights, the better

There are generally 2 types of light whose qualities have the potential to cause interference.

Older types of Christmas lights that are arranged in a string of low voltage lamps in series with each other and are designed to blink can cause radio interference which can lead to dips in Wi-Fi speed.

More modern Christmas lights use solid-state LED’s and have an external control for flashing which don’t create radio noise. However, it’s worth noting that some LED’s have a chip inside the bulb to control the blink and these devices can also cause interference.

On the whole though, modern lights are definitely less likely to cause you a Wi-Fi problem, so maybe save yourself the annual horror of trying to untangle your 10 year old string of lights and treat yourself to some new ones.

 

Rule #4 – Don’t put your router in ‘high traffic’ areas

Tis the season for family gatherings, friend get-togethers and all sorts of festive shenanigans. Not to mention the big man in red tumbling down the chimney! Humans are great signal absorbers, so put the router in a place where it won’t get blocked by partying people or round bellies that shake like jelly.

 

Did you do the Wi-Fi speed test before and after? We’re pretty sure the results will be rather negligible but we’d love to hear your results!

The Fundamentals of a Wireless LAN

We were going to call this blog ‘WLANs for Dummies’ but that seemed a bit harsh so we settled on the fundamentals of a wireless LAN instead.

A wireless LAN, or WLAN, might seem complicated on the surface but actually it really just follows simple laws of physics. If you can understand these and follow them, then there shouldn’t be any reason why you can’t achieve high performance and scalability for your WLAN.

If you can understand the basics of wireless physics, then you can start to plan your WLAN for a successful deployment. It will also help you to troubleshoot an existing WLAN exhibiting issues.

How Does Data Travel Through a WLAN?

First things first – Let’s look at wave properties.

Data transmits, or travels, from one point to another – e.g. between wireless access points – via electromagnetic waves. This energy travels at the speed of light and operate at different frequencies.

The frequencies of these electromagnetic waves are defined by how many periodic cycles are completed by second.

For example:

How is Frequency Measured?

As we said above, frequency is how many wave cycles are completed per second. This is measured in Hertz. A 2Hz waveform is 2 completed wave cycles in a period of 1 second.

How Does Frequency Affect a WLAN?

A phenomenon called Free Space Path Loss is something that causes signal loss when a waveform travels from one point to another. This is what affects how well data travels across a wireless network.

Different wavelengths (frequencies) experience difference signal loss. The lower the frequency, the longer the wavelength, and the longer the wavelength, the further it can travel before signal gets lost.

For example, 2.4GHz have longer wavelengths than higher frequencies like 5GHz.

How is Wi-Fi Signal Loss Measured?

We measure the energy that is associated with received wireless signals in Decibels (dB). We can also measure loss of signal in this way.

Decibels are logarithmic. On the linear domain, when you add decibels it grows exponentially and when you subtract decibels it reduces exponentially.

The 3dB rule

Every 3dB change, there is a doubling of energy (if increasing) or a halving of energy (if decreasing).

As a ratio, this would look like:

If we had the wireless signal energy at
1:10dB

Then doubling it would be
2:13dB

Remembering this rule can help with both analysing the energy associated with wireless signals as well as predicting it.
Similarly, if you add or subract 10dB, it changes by a factor of 10.

The Relationship Between Frequency and Wireless Signal

Let’s take a look at 2.4Ghz and 5GHz frequencies or waveforms. 5GHz is a higher frequency, so has more wavelengths in a given time period. 5GHz has more wireless signal loss (attenuation) than 2.4GHz, and thus is better for high-density areas. 2.4GHz has less wavelengths in a given time period and is better suited for wider coverage. Bear this in mind when you are planning or troubleshooting a wireless network.

How is Wireless Signal Affected by Different Materials?

In an ideal world, you would have a clear line of sight between your wireless points. In reality, this is rarely the case and you will often find things that get in the way and stop the wireless signal from traversing effectively across your network.

Different materials will affect wireless signals and attenuation in different ways.

Materials such as concrete will cause more attenuation of wireless signal than wood.

In scenarios where wireless signals can propagate (the action of spreading) normally, there is no interference from other materials. However, there are some things that can alter the propagation of a wireless signal, causing it to behave differently and potentially become unreliable.

For example, a WLAN environment with metal surfaces may encounter unpredictability with wireless signal due to it reflecting off the metal.
Wireless signal can also be absorbed by certain materials like water or people, causing the signal to falter.

Being mindful of materials during the WLAN planning stage can help ensure the environment doesn’t hinder your wireless network and you have reliable connectivity results.

Co-Channel Interference

Different materials aren’t the only thing that can interfer with wireless signals.

Due to the 2.4GHz and 5GHz frewuency bands being unlicensed, there are no restrictions on people when extending wireless networks with access points.

This means that they can become crowded as well as channels not being assigned efficiently. Both of these issues can cause co-channel interference.

When planning your WLAN it’s important to take these issues nito consideration and plan your wireless network accordingly so as not to risk problems with wireless signal later down the line.

You want your WLAN to be as effective and efficient as it can possible be, which takes planning and wireless network knowledge.

Whilst the 2.4GHz is popular due to its propagation qualities due its waveforms passing through materials like walls more easily and reaching end users at a long distance. This however has meant that its become crowded with competing devices such as cordless telephones, baby monitors and bluetooth devices. This saturation can cause problems with your wireless signal.

In comparison, the 5GHz spectrum has greater availability and relaxed transmission power giving it more flexibility when it comes to wireless networks.

The 2.4GHz band has only 3 channels without any overlap, whereas the 5GHz has 24. This is another reason why the 5GHz band is favoured for high-density WLAN environments.

Understanding Frequency Channels

To ensure you can maximise the performance and scalability of your WLAN, you need to understand how these channels operate and use that knowledge to avoid co-channel interference.

Let’s take an Access Point as an example. An AP will have a specific bandwidth through which it will transmit and receive signals to and from other points. The channel assigned to the AP will be appropriate for the centre frequency of the first 20MHz channel used by the AP.

This bandwidth is specifically the frequency range over which the data signals are transmitted. Peak transmission and power is spread over the range of that bandwidth, with it dropping off at the edges.

These edges are then at risk of meeting other nearby wireless networks and are prone to interference from the ‘noise’ of these other networks.

It’s important to use what you know about channels to prevent the reduction of wireless signal speed and loss of scalability of your wireless network.

In order to minimise interference between neighbouring access points, choose to assign them with non-adjacent channels. Following this will make it easier to scale your network. If you don’t follow this principle, you will likely encounter problems with latency and throughput.

The best way of reducing interference when assigning WLAN channels is to carry out a Wi-Fi site survey. This involves analysing the noise levels across the spectrum so you can make informed decisions for your wireless network.

Ubiquiti Wi-Fi Expert Help

Here at Geekabit, we love Ubiquiti – It’s no secret. We’re often asked what bits of Wi-Fi kit are our favourites, and Ubiquiti is definitely one of them. We use Ubiquiti wireless devices so much that we consider ourselves a bit of an expert when it comes to Ubiquiti Wi-Fi installations. We’ve done quite a few blogs sharing our expert knowledge of Ubiquiti Wi-Fi devices, so this week we thought we’d do a quick round-up on some of the things we’ve touched on.

Let’s start with how Ubiquiti UniFi could help your business. This blog was the first in a series of three looking at the benefits of Ubiquiti UniFi in a business setting. If excellent, reliable Wi-Fi is critical to your business operations, then this is well worth a read.

Which Ubiquiti airMAX product should I choose?

It’s no secret that we’re big fans of Ubiquiti products here at Geekabit. We often recommend their devices and bits of kit for our clients and business Wi-Fi installations.

This blog is going to look at some of the different Ubiquiti airMAX products there are and which ones might be suited to your business and Wi-Fi needs. There are lots of different options that cover various outdoor wireless scenarios.

 

Point-to-Point or Point-to-Multipoint?

Let’s start at the beginning. First you need to ascertain whether your outdoor Wi-Fi would be best suited to a Point-to-Point (PtP) or Point-to-Multipoint (PtMP) network. These are the two primary deployment methods for distributing any fixed outdoor wireless communications.

Point-to-Point (PtP) – This method connects two locations, usually at a distance of multiple km, and essentially forms an Ethernet bridge.

Point-to-Multipoint links (PtMP): This method can connect three or more locations, via one Base Station (or Access Point) and multiple CPE devices (Stations) connected to the Access Point.

 

Point-to-Point (PtP) Links

Here are some of the Ubiquiti airMAX products with specifications on what wireless environment they would cater for. Whilst there are distances listed below, these are meant as a reference. It’s important to bear in mind that all real-life results have influencing environmental factors, for example, interference and Line of Sight.

Short distance (0-5 km)

NanoBeam 5AC-G2: This is recommended for short links, and exhibits superior performance which is due to the latest airMAX AC technology. It is able to deliver up to 450Mbps of throughput.

NanoStation 5AC Loco: Another good option for short distance links, this is the lowest cost PtP solution that has airMAX AC technology.

NanoStation 5AC: This one is a popular choice when it comes to short link Wi-Fi, and is commonly chosen for video surveillance due to its dual-Ethernet port capability. It also has airMAX AC technology.

Medium distance (5-15 km)

LiteBeam 5AC-23-G2: This is recommended as Customer Premises Equipment (CPE – any device accessing the internet) for most cases. Thanks to the latest airMAX AC technology, it has superior performance and can to deliver up to 450Mbps of throughput.

PowerBeam 5AC-G2: Recommended as CPE for medium or long distance links. Once again it has superior performance thanks to the latest airMAX AC technology. It can to deliver up to 450Mbps of throughput.

PowerBeam 5AC ISO:  This one is very similar to PowerBeam 5AC but offers an alternative for high-noise environments.

 

Point-to-Multipoint (PtMP) Links

When it comes to PtMP outdoor wireless networks, it’s really important to remember that the performance is dependent on both sides of the link. If you are trying to get across long distances, you’ll need to make good choices when it comes to the Base Station and CPE for each case. We’ll be looking at these options below.

The release of Ubiquiti operating systems airOS 6 (for M devices) and airOS 8 (for AC devices) provides backwards compatibility and means that you can upgrade your M sector by simply swapping the M AP for an airMAX AC radio as the AP.

 

Base Stations

You will usually find the location of a base station on the top of a tower, building or mast. Your maximum coverage will be determined by the height of that tower.

Low Capacity and Short distance Base Stations

For short distance base stations with low capacity, take a look at the following Ubiquiti airMAX products. These are ideal for areas with low interference.

Rocket M + airMAX OMNI antenna: This could be a great option for more rural Wi-Fi needs, particularly as it is susceptible to interference. It can support up to 60+ concurrent stations when all devices are airMAX capable.

High Capacity & High-Performance Base Stations

Rocket 5AC PRISM G1/G2 + airMAX AC Sector Antenna: This one’s for the highest performance base stations with carrier-grade system. Eight 45° antennas give 360° coverage. Co-adjacent noise is significantly reduces with airPRISM technology.

Rocket 5AC Lite + Titanium Sector Antennas: For medium-high density areas, this is a high-performance solution. It uses the latest airMAX AC technology plus variable beamwidth (60-120°) antennas for scalable growth.

LiteAP AC: This one is an ultra-lightweight airMAX AC sector + radio. It has incredible performance and disruptive pricing, plus 120° coverage.

 

Customer Premise Equipment (CPE)

One of the great things about Ubiquiti is the range of products and how they can work together to support your wireless network as a whole. If you go for the airMAX CPE to support your Ubiquiti products, you’re also getting centralised SDN management, hotspot/guest portal, advanced SSID/WLAN configuration, routing, switching and more. It’s well worth looking at the whole range available. Or call the experts (that’s us) to see whether Ubiquiti wireless devices could help with your wireless network.

Short distance (0-3 km)  

NanoBeam 5AC-G2: This has slightly greater range than the NanoBeam 5AC-19 M and is more directive.

Medium distance (3-7 km)

LiteBeam 5AC-23-G2: This low-cost CPE has very narrow beamwidth, and MIMO technology. This one is the new industry-standard for airMAX AC CPEs.

PowerBeam 5AC-G2: This option is a highly directive CPE, with better range and lower noise.

Long distance (7+ km)

PowerBeam 5AC-500/620: This one is a higher power device, with a super directive antenna, better range and lower noise. If you’re a design buff then you might also like how it’s more aesthetically pleasing compared to bulky dishes.

Rocket 5AC-Lite + RocketDish LW: You’ll likely find this one the best performing option. It’s higher cost than integrated designs, and can be unsightly as a CPE. It supports IsoBeam accessory for better isolation, which comes with RF chokes.

 

Frequency Options

Let’s talk about frequency. Due to physics and utilisation, each frequency has different characteristics.

Lower frequencies have better propagation characteristics than higher frequencies. You may find that they work better in environments where the Line of Sight is obstructed (for example, by trees). However, these bands may also have higher levels of noise and interference, so it’s very important to select the frequency that works best for your wireless environment.

Let’s have a look at the pros and cons of some frequency bands.

900MHz (M900) – Pros and Cons

  • Better tolerance for trees and small obstacles in comparison to higher frequencies
  • Tends to have higher noise levels
  • Only has a 26MHz bandwidth

2.4GHz (M2) – Pros and Cons

  • It is unlicensed worldwide
  • It only has 3 over-lapping 20MHz channels (1, 6, 11)
  • It tends to be a very crowded band with interference from other devices such as cordless phones
  • 40MHz channelse are not recommended

3.x GHz (M3-M365) – Pros and Cons

  • 300MHz bandwidth in countries where 3.4-3.7GHz band is available
  • It is noise free in most areas
  • Only 25MHz bandwidth in countries where 3.65GHz can be used
  • It requires a license

5 GHz (5AC/AF5/AF5X) – Pros and Cons

  • It is unlicensed worldwide
  • Higher EIRP limits allow higher gain antennas, and long distance links
  • Large amounts of spectrum available, easier to co-locate nearby devices
  • Weaker propagation in comparison to lower frequencies when there are obstacles like trees or walls are present

10 GHz (M10) – Pros and Cons

  • It is noise-free in most cases and is very useful when the 5.8GHz band is crowded
  • It has a very small Fresnel zone
  • It is only available in a few areas
  • It is a licensed band
  • It needs a perfectly clear Line of Sight

11 GHz (AF11FX) – Pros and Cons

  • It is noise-free in most cases and is very useful when the 5.8GHz band is crowded
  • It has a very small Fresnel zone
  • It is only available in a few areas
  • It is a licensed band
  • It needs a perfectly clear Line of Sight

 

Antenna Types

We spoke about the important of each side of the link being effective to ensure the highest performance possible. Now it’s time to talk about the antennas.

High gain antennas also play an important role when deploying a high performance outdoor wireless network. There are two main reasons:

  • They provide high gain amplification of the signal power resulting in higher signals and better link quality.
  • They are highly directional, which gives them spatial filtering characteristics that can help to block noise. This is especially important in noisy environments.

When thinking about the antenna for the base station, you might think it’s best to go for the one that offers the largest coverage area. However, it’s actually better to choose the antenna that covers the smallest amount of coverage that covers your range area. An antenna covering a larger area than needed could be more susceptible to interference due to a wider beamwidth, causing a decrease in scalability and performance.

Here are the categories of antenna.

Yagi: Directive, used for PTP and CPE applications. Frequently used in low frequencies, such as 900MHz, due to size

Grid: Directive, used for PTP and CPE applications. Great wind-loading properties. However, this type only works in one polarity (1×1), so lower performance than 2×2 antennas (Dish, Panel, etc.)

Panel: Directive, used for PTP and CPE applications. Compact design is very attractive in situations where dishes are not preferred.

Dish: Most Directive, highest performing airMAX antennas for PTP applications. Usually larger and heavier.

Omni: Provides 360 degrees of horizontal coverage (omni-directional). Ideal for low capacity and wide-coverage AP / Base Station applications)

Sector: Ideal choice for high performance Base Stations. Offer higher gain and directivity than omnidirectional antennas. Usually offered in 45, 60, 90, or 120 degree options.

This list is not conclusive. You can find all of the current airMAX antennas here by looking at the antenna section.

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 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)

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!

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 frequenceis 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.

How Will Wi-Fi 6 Affect the Battery Life on my 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 devices 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 wave 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 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.

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. Or perhaps if you live in a densely populated place, like a block of flats.

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

There are various features that help Wi-Fi 6 better tackle the problem of heavily crowded networks. 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!

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?

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?

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.
