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.

Why Is Network Design So Important for Reliable Business Wi-Fi?

Wi-Fi is no longer a ‘like to have’ when it comes to successful business planning. It’s vital for businesses to have strong, reliable Wi-Fi in order to business processes to run smoothly.

No matter what industry your business is in – Wi-Fi is crucial. Gone are the days when everything could be wired and cabled. Whether you run a warehouse, a hospital or operate out of an office; Your business needs to run wirelessly.

Organisations tend to have an armada of laptops, tablets, smartphones and other IoT devices that require effective Wi-Fi.

So if the need for a good Wi-Fi connection is so prevalent, why are we still seeing so many businesses struggle with their Wi-Fi network?

The requirements can be demanding, and to be successful a network needs to meet those demands. Plug-in-and-go routers aren’t going to cut it unfortunately. Your business network needs more!

So how can you ensure that your network can be relied upon by your employees every day, so they can do their job productively and efficiently?

It all comes down to the design.

What do you need to consider when designing a Wi-Fi network?

Designing your wireless network gives you the chance to translate your business needs into a Wi-Fi network that will work for you and meet those needs.

So what do you need to consider?

Capacity

You need to think about how many devices will require a Wi-Fi connection. You need to be asking questions like how many employees you have, are there people in addition to employees that will need to connect, how many devices are each of these people likely to have and what type of device are they.

Getting to know how much traffic you will likely have will help you to determine how much bandwidth you need in order to meet consumption needs.

If you don’t get the capacity planning right, you could end up with very unhappy employees suffering with slow internet speeds and an intermittent connection. Neither are conducive to a productive work environment!

Something else to consider is how the capacity changes as you move around your site. Do some locations have a higher capacity demand than others? This information will help you to design a network where access points are distributed according to requirements.

Capacity isn’t just important during the planning stage either. It’s something you will need to monitor so that you can identify when more devices are trying to connect and adapt the network accordingly.

 

Coverage

We’ve talked about capacity and how many devices are likely to connect. Now it’s time to talk about where those users need that connection.

Identifying your coverage area allows you to optimise the distance between your wireless transmitters. Getting this right means that you’ll have the right signal strength for the Wi-Fi enables devices trying to connect.

Coverage is split into two – Primary coverage and Secondary coverage. Interweaving the primary coverage area of your transmitters with the secondary coverage of necessary overlaps means that your end users will be able to roam throughout your site without their connection dropping out on their device.

The idea is to find the perfect balance in the number of AP’s you deploy. Too many AP’s not only costs you more money on installation but can also cause interference. Not enough AP’s and you won’t be able to meet your coverage needs.

 

What is the Least Capable, Most Important Device?

It’s important to identify what device is most business critical – And whether that device poses a risk to the rest of your network. You might find that a warehouse scanner, or even an employees laptop, is critical to the needs of the business, but is also the oldest and least technologically advanced device on the network.

You need to identify this device (or devices) and make sure that your network will ensure the device(s) stay online. You can do this by checking the manufacturer specifications and make sure these align with your network offering.

 

Are there any Obstacles on site?

It’s a good idea to walk around your site and identify any potential obstacles to your wireless signal. Sometimes having an actual walk-around sheds more light on potential problems than just looking at a simple floor plan. You need to know exactly how the radio frequency will behave in your specific environment.

Consider things like high or exposed ceilings, columns, large items of furniture, lift shafts, stairwells and even signage.

You should also look to see where access points could be easily installed, and any areas where this would not be possible. This also goes for cabling.

Mitigating the Effects of Wall/ Door Material on Signal Attenuation

In order to mitigate the risks of attenuation, you need to understand what materials could pose a problem to your Wi-Fi signal.

When you are designing your Wi-Fi network, it’s imperative that you identify the physical characteristics of your environment and understand how this can impact your wireless signal.

The amount of signal strength absorbed by walls or doors depends on what they are made from. A rough guide to this would be:

  • Bookshelf – 2dB
  • Drywall – 3dB
  • Exterior Glass – 3dB
  • Solid Wood Door – 6dB
  • Marble – 6dB
  • Brick – 10dB

Having this information specific to your site means you can design a wireless network that works really well.

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.

Business Wi-Fi Facebook Wi-Fi Wi-Fi
What is Facebook Wi-Fi?
If you’re not one of the 100,000 businesses already using Facebook Wi-Fi then you may very well be asking this question! Facebook have launched their own Wi-Fi option, to help businesses connect with more people.

How does Facebook Wi-Fi work?

Most businesses will allow people to connect to their Wi-Fi – Sometimes with a password (recommended) and sometimes without. Whilst it’s much more secure for both your network and the guests using it to provide people with a Wi-Fi password, some may feel it’s a bit of a faff logistically.

This is where Facebook Wi-Fi helps – It allows people to connect to your business Wi-Fi without needing to share a password. Not only can it make things easier logistically, it could also help your business to reach new customers by increasing the number of check-ins to your Facebook Page. That way, your customer’s friends will discover you too!

What are the benefits of Facebook Wi-Fi?

  • As we’ve just mentioned, by utilising Facebook Wi-Fi in your business, you encourage users to check in, which in turn increases your exposure to a new audience and reach more potential customers through friends.
  • Currently, the most secure way to share Wi-Fi access is to give users a password to enable them to connect. Businesses have varying methods of sharing password information with their customers, but it can be frustrating for customers if they can’t find the information and arnd are keen to connect quickly. Facebook Wi-Fi means that people visiting your business won’t need a password in order to log connect to your Wi-Fi – You won’t need to share passwords with Facebook Wi-Fi.
  • Because it’s linked to your business Facebook page, you are able to gain insights on your visitors. Anonymous information is collected so you can identify how many returning visitors you have checking into your page through Facebook Wi-Fi.
  • It’s free! There is no charge to use Facebook Wi-Fi for your business.

How do I get Facebook Wi-Fi for my business?

If you’re eager to get started, you’ll need to add the Facebook Wi-Fi features to your existing Wi-Fi.

First of all, you will need to have a business page on Facebook and admin access to the page. Make sure your business has a physical address listed in the Page Info section.

You will also need to have a compatible router. If it is compatible, you need to enable Facebook Wi-Fi in your router’s settings.

If both admin access and router compatibility are in place set up could be complete in as little as 20 minutes!

Is my router compatible with Facebook Wi-Fi?

First, you need to know what router you have. You can find this information on your router box, or by typing your router’s IP address into your browser. Once you know what router you have, you can check to see if it’s compatible with Facebook Wi-Fi here. The list comprises of some of our favourite brands of business Wi-Fi kit, including Ubiquiti UniFi, Meraki, Aruba and Ruckus among others.

If your router is on the list, you can then click through to a handy set up guide on YouTube, specifically for your router. Easy peasy!

If your router isn’t compatible with Facebook Wi-Fi but you’re really desperate to use it, you’ll need to invest in a new router that is compatible.

Want to know more about Facebook Wi-Fi?

You can find more information about Facebook Wi-Fi on their website here.
