Top UK Mobile Networks for H2 2023 Revealed by RootMetrics Benchmark

How did UK mobile networks perform in the second half of 2023 when it comes to 4G, 5G and mobile broadband?

RootMetrics (now an Ookla company), a mobile analyst firm, has not long published their latest benchmark study of UK mobile networks (4G and 5G) and mobile broadband performance for H2 2023. 

RootMetrics offers scientifically collected and crowdsourced mobile network performance information to consumers and the industry. The firm captures user information by testing network performance when consumers are using their mobile phone for voice or data communications. 

Results of the latest biannual benchmarking report which once again see EE (BT) come out on top against their UK network rivals at Vodafone, Three UK and O2 (VMO2). 

Which UK mobile network is the best for 4G/5G?

When it comes to 5G performance, the picture painted by this recent report isn’t so clear-cut.

This latest study used data from a 5G-enabled, latest model of Samsung smartphone (the actual model was not disclosed in the report). It was purchased from operator stores and tested for both 4G and 5G performance across all 4 primary UK operators within 16 of the most populated UK cities. 

In summary, the study consisted of:

  • 1 latest model Samsung smartphone
  • 4 primary UK mobile operators
  • 16 UK cities
  • 634,942 tests across hundreds of locations
  • 788 locations were indoor
  • 24,179 miles driven during both the day and night

Results were divided into the following categories:

  • Network reliability
  • Speed
  • Data
  • Call and text quality

Scores were given out of 100 (100 being the highest score). As you can see from the data representation from RootMetrics below, EE came out on top across all categories, while VMO2 were found at the bottom of most. 

Interestingly, every one of the 4 primary UK operators saw a decrease in their overall scores when compared to the last RootMetrics report 6 months prior. 

The Overall Scores for H2 2023 (vs H1 2023), in order of best to worst, are:

1. EE – 94.2 (down from 95.9)
2. Vodafone – 90.1 (down from 92)
3. Three UK – 89.3 (down from 90.2)
4. O2 – 86.4 (down from 86.7)

So which is the best UK mobile network? When we look at the average (median) UK download speeds for both 4G and 5G networks, then the strongest data speeds were delivered by EE (68.6Mbps, which was up from 65.1Mbps in the last report).

Vodafone also saw an increase in data speeds, increasing to 34.5Mbps (from 29.4Mbps). Despite O2 improving their data speed score from 15.5Mbps to 19.9Mbps, they still scored the bottom of the 4 providers. Just behind Vodafone to take 3rd place, Three UK fell slightly to 32.3Mbps (down from 34.7Mbps). 

How is 5G performing on UK networks so far?

However, when we look purely at 5G networks, we see a bit of a different picture emerge when compared to the previous report for the first half of 2023. 

Whereas H1 2023 saw Three UK as the fastest median 5G download performance, that award now goes to EE. O2 were unfortunately at the bottom with a score well below the other 3 primary UK networks. The scores for median download speeds for 5G from the H2 2023 report were:

  1. EE – 174.1 Mbps
  2. Three – 165.7 Mbps
  3. Vodafone – 158.3 Mbps
  4. O2 – 68.7 Mbps

What is the availability of 5G on UK mobile network providers? 

As well as 5G speeds, the availability of 5G across UK networks was also tested. 

All 4 of the UK mobile network providers had 5G availability of over 52% during this latest UK wide testing. 

The UK providers in order of 5G availability are:

  1. Three – 57.6%
  2. O2 – 54.5%
  3. EE – 52.3%
  4. Vodafone – 41.9%

You can find more data below for particular regions as well as the most improved cities. 

What can we take away from this report on 5G speed and availability on UK mobile network operators?

So it would seem that even though EE has the fastest 5G speeds, that 5G connection is less available than that of its competitors Three and O2. 

Despite coming second place in terms of speed, Three weren’t too far behind EE and are also slightly more available. 

O2 might have decent 5G availability, but the speed of that connection is pretty dire according to this latest report. 

In terms of 5G speed, Vodafone aren’t too far behind rivals EE and Three, however they are at the bottom of the pile with the lowest 5G availability. 

What more would we like to know about 4G/5G connections across the UK mobile networks? 

If you’d like to read more on this and see further data, head to the full report from RootMetrics UK Mobile Performance Review 2H 2023 here

Whilst this review does shine a light on 5G speeds across the UK and how UK mobile networks are performing, it does only give select information. 

It would be interesting to also see how the networks perform when it comes to upload speeds and latency using 4G/5G connections. 

As you can see from the review, there seems to be a strong focus on urban areas across the bigger cities in the UK. Here at Geekabit we talk a lot about the struggles of rural businesses and more remote locations that still need strong 4G/5G mobile broadband connections. Some more data on the performance of UK mobile networks in these areas would be beneficial and would give a clearer picture of 4G/5G availability and speed across the UK as a whole. 

London Underground: 5G Deployed by Virgin Media O2 UK 

Last month, VMO2 became the last of the four primary mobile providers to begin their deployment of their ultrafast 5G mobile broadband service on the London Underground. 

Their 5G mobile broadband has been deployed on the:

  • Central Line – Between Queensway and Holland Park
  • Northern Line – Between Kentish Town and Archway 

5G Mobile Broadband on the Central Line

If you are a commuter on the Central Line, the Underground tunnels between Queensway and Holland Park now have 4G and 5G services following the new roll out. 

You should experience seamless connectivity when travelling through these stations. 

Nestled between Queensway and Holland Park is Notting Hill Gate Station, which has now been upgraded to be a fully 5G station. This means that Central Line platforms and ticket halls at this station will now have this latest mobile network available. 

The stations at Queensway and Holland Park have now had 4G introduced.

5G Mobile Broadband on the Northern Line

As a commuter on the Northern Line, you should now be able to connect to 5G from Archway to Tufnell Park stations. 

Kentish Town station will also now have 4G connectivity.

Shared Platform from Boldyn Networks 

The same network platform from BAI Communications (Boldyn Networks) is being shared by all of the primary operators.

Transport for London have a 20 year concession deal with BAI. This allows them to build the infrastructure needed for fibre-fed mobile connectivity, and then make it available via wholesale. 

Revolutionised Commuting in the Capital

Having Underground connectivity has long been a dream for commuters travelling around London using the tube. 

Chief Commercial Officer for VMO2, Gareth Turpin, says:

“For the first time, our customers can access the latest 5G mobile services deep under London. This is set to revolutionise commuting in the capital, and in the weeks and months ahead we’ll be rolling out ultrafast mobile services at more Tube stations, in tunnels and on platforms to bring high-speed connectivity to our customers as they travel on the Underground.

This is part of our commitment to upgrading the UK and ensuring customers can access our network wherever they are.”

When will all of the London Underground have 4G / 5G mobile broadband connectivity?

The network coverage is set to expand further throughout this year. 

Back in 2020, earlier work by TfL and other mobile operators meant that there are already 4G services on the Jubilee Line between Canning Town and Westminster stations. 

Last month we saw the additions on the Central and Northern Lines outlined above. 

The target is for ticket halls, platforms and Underground tunnels throughout the London Underground network to have 4G and 5G connectivity by the end of 2024. 

Keep your eyes peeled for further announcements!

4G and 5G Mobile Broadband Antennas: Frequently Asked Questions

Last week we blogged about 4G and 5G antennas – How to choose them and how to install them. If you are planning to choose and install your 4G/5G mobile broadband antenna yourself, then you might end up asking one or more of the below commonly asked questions. 

As always, if you’re feeling unsure about which antenna you need or how best to install it, then perhaps consider calling in the experts.

Otherwise, let’s have a look at some of the questions that might arise when you’re installing a new 4G/5G mobile broadband antenna. 

4G/5G Mobile Broadband Antennas – Frequently Asked Questions and Handy Hints

Q: My antenna works better on a window than it does outside – Why is this?

Unfortunately when it comes to installing 4G/5G mobile broadband antennas, the most logical solution isn’t necessarily the right one for your property. Hence why sometimes you might find that despite doing everything correctly, you find that your signal and data speed is better indoors (e.g. from your smartphone) than it is the correctly positioned external antenna. This could include getting a better signal and speed from an antenna on a window rather than the top of your property. 

If you find yourself in a situation like this, then the best course of action is to understand the signal readings and bands being used as best you can at various locations around your property. 

Remember that; 

  • Mobile signals can be affected by lots of things – Such as reflections from environmental objects and even the weather. 
  • The router you use can also mix things up by automatically switching bands which could result putting you on one with a slower speed. 

The best way to get an idea of how your antenna and router are responding to the signal is to test different locations around your property and take some measurements. 

Q: How do I know which is the best mobile service for my area? 

There are a couple of ways you could go about this. If you have a friend or colleague on a different network to you, then you can ask to borrow their smartphone and test out the broadband speed in different locations. 

For accurate results when doing this, try to ensure;

  • You test out all the available networks 
  • Use a smartphone that is as up to date as possible 
  • Use a handset on a Pay Monthly SIM (they are less likely to have data restrictions that a PAYG)

You could also consider calling an expert to carry out these tests for you. Our friendly and knowledgeable engineers can visit your property (home or business) and perform no-obligation tests to ensure that a suitable 4G signal and speed can be achieved at your property, and advise on the best equipment and hardware to attain optimum speeds. We do this with specialist signal analysers that provide printable reports showing the best setup.

Q: What is Carrier Aggregation (LTE Advanced) and does my router need it? 

Carrier Aggregation, or CA, means that the router can boost performance by combining several different radio spectrum bands at once. 

You should find that most of the latest 5G networks and urban 4G deployments support CA. 

Unfortunately it’s possible that some rural areas are not reached and so are not supported. However, it’s wise to buy kit that does support CA to ensure you are covered. You should get support for a good selection of bands and speeds from modern mobile routers.

Some things to look out for;

  • Devices that support the 3GPP release 10 standard (they also support LTE-Advanced).
  • From Release 12 and onwards, CA became much more refined.
  • 5G features tend to start from Release 14 and onwards.
  • LTE Categories – These can help you to identify the theoretical peak downlink and uplink speed of a 4G modem. The higher the category, the higher the download/ upload data handling capacity. Remember though, these are theoretical peaks and even on the best networks with optimum signal, lots of CA and capacity you might still not reach that peak.

Q: How do I know which connector I need for my 4G/5G mobile antenna? 

Wouldn’t it be simple if all mobile routers and antennas came with the same external port type? Unfortunately, they don’t – In fact, some routers don’t even allow external antennas! 

Before buying your kit, make sure that both the router and the antenna are compatible with each other in terms of connectors and sockets. 

Types of connector you are likely to come across are:

  • SMA (most common)
  • TS-9
  • CRC9
  • RP-SMA
  • TNC
  • BNC
  • N-Type
  • MMCX
  • FME
  • U.FL.

Already bought the kit and found that the connectors don’t match up? Don’t panic – You should be able to buy an adaptor cable to convert two different types of connector. 

Q: What is a CELL ID and how can I use it to fix performance issues? 

A CELL_ID is the number your device will show for the mast or tower that it’s getting it’s signal from. So where you might not be able to see what band is being used (some devices and apps won’t show you this information) you can still see what the CELL_ID is and whether it changes. 

If the CELL_ID number changes, this means that the signal is coming from a different source. This could indicate that the band has also changed. Monitoring this information can help you work out any issues with performance. 

Q: I’ve got bad signal with good speed, and bad speed with good signal – What is happening?

Unfortunately, a good signal doesn’t automatically mean good speed. We know, it doesn’t seem fair does it?

The reason this can happen is that you could be receiving an excellent signal, but the band you are connected to is congested with lots of users. 

You could also have great signal, but little capacity to carry data through not enough spectrum frequency. 

It also works the other way – You could have a poor signal but find you’ve got decent speeds. Yes we know it seems bonkers. Mobile signals can be affected by various factors so the best thing to do is to keep on testing until you work it out! Or call in the experts and let us do the hard work for you. 

Q: I can see I’ve got good mobile signal from the antenna, but I’m still having connection problems – Why? 

Remember that your connection is only as good as your router. You could receive a strong, fast signal to your correctly located antenna, but the Wi-Fi (ie. the signal from your router to your device) is poor, resulting in connection problems. 

Your mobile broadband router needs to be able to take the signal from your antenna and transfer it to your device. You can find more tips on how to fix common Wi-Fi problems (like your router location) on our blog

How do you know whether it’s the antenna that’s the problem or the Wi-Fi? The easiest way to test where the issue is, is to plug your device into the router through a LAN port. If the signal and connection is still poor, then it’s your antenna. If the signal and connection is strong, then the problem lies with the Wi-Fi. 

Hopefully this blog has helped iron out some of the commonly asked questions when it comes to installing a 4G/5G mobile broadband antenna and some of the issues you might run into.

PCI: What Is The Difference Between 4G LTE and 5G NR

In this blog we are going to look at the difference between 4G LTE and 5G-NR, specifically in terms of PCI. 

 

What is PCI when it comes to 4G / 5G?

 

PCI is the Physical Cell ID and is one of the most important ways a cell identifies itself in a 4G or 5G wireless network.

The physical layer (or PHY-layer) Cell ID is what determines the Cell ID Group and Cell ID Sector, and it is this that is needed for DL synchronisation. 

DL (Downlink) Synchronisation is the process in which a UE (phone) detects the radio boundary and OFDM symbol boundary. In other words, the exact timing of when a radio frame or OFDM starts. (In telecommunications, orthogonal frequency-division multiplexing (OFDM) is a type of digital transmission and a method of encoding digital data on multiple carrier frequencies.) 

This DL synchronisation process is done by detecting and analysing the SS Block. From a UE’s (phone’s) point of view, Downlink is the ‘receiving’ transmitting direction. The SS Block (SSB) stands for Synchronisation Signal Block and refers to the synchronisation signal and Physical Broadcast Channel (PBCH) as a single block that always moves together.

 

Why is PCI Planning important? 

 

If you are planning, designing and deploying a 4G / 5G network, then PCI Planning will be one of your most important steps. 

Making sure your network is properly designed with PCI in mind will ensure your network works efficiently and increases how your resources are utilised. 

Excellent PCI planning ensures QoS for those who are subscribed to your 4G / 5G network.

QoS (Quality of Service) is the use of technologies to control traffic on your network, ensuring that the performance of critical applications meets requirements.

The key goal here is to use QoS and PCI Planning to enable your network to prioritise traffic, offering dedicated bandwidth and lower latency.

PCI is one of the technologies used to enhance performance of business applications, WANs and service provider networks. 

Poor planning in this area can result in PCI collisions and conflicts – Which in turn, negatively impact the overall performance of your network.

 

How is the PCI value created?

 

The PCI value is created from two components – PSS (Primary Synchronisation Signal) and SSS (Secondary Synchronisation Signal). 

The PSS is used to obtain the slot, ub-frame and half-frame boundary as well as providing the cell identity within the cell identity group. 

The SSS is used to obtain the radio frame boundary (10ms) as well as enabling the UE (phone) to determine the cell identity group.

After your UE (phone) has successfully decoded the PSS and SSS, it will be able to calculate the PCI. It uses the following formula:

PCI = (3 × SSS) + PSS

 

How is PCI calculated for 4G?

 

PSS has 3 values (0,1 and 2) and is created using the Zad-off Chu sequence.The PSS helps to accomplish slot and symbol synchronisation in the time domain.

SSS has 168 values (0 to 167) and is produced using concatenation (linking together in a series) of 2 m-sequences (max length sequence). The SSS helps to achieve radio frame synchronisation.

The formula to work out PCI for 4G is therefore:

PCI = (3 * 167) + 2 = 503

This means that there are PCI values varying from 0 to 503 LTE, which in turn supports 504 unique PCIs for 4G. 

 

How is PCI calculated for 5G?

 

PSS has 3 values (0,1 and 2) and created using m-sequence. 

SSS has 336 values (0 to 335) and is generated using the product of 2 m-sequences.

In 5G-NR (a new radio access technology developed by 3GPP for the 5G (fifth generation) mobile network), the basic structure of PSS is the same but the number of SSS is increased.

The formula to work out PCI for 4G is therefore:

PCI = (3 * 335) + 2 = 1007

So the PCI values will vary from 0 to 1007. This means that 5G-NR can support 1008 unique PCIs.

 

What does this difference in PCI between 4G and 5G actually mean? 

 

In the simplest terms, 5G-NR has double the number of PCI’s, compared to LTE 4G. 

5G has more Physical Cell IDs (the actual area that the cell antenna on a cell site is covering). Each 5G NR cell has a Physical Cel lD. 5G has 1008 unique possible Physical Cell ID’s, whereas 4G has only 504. 

So if we’re connected to Vodafone on Physical Cell ID No.1, but we could also see Vodafone signals being broadcast out of that cell tower on different cell antennas using Physical Cell ID No,2 and No3, then our mobile device would know to connect to No1. It would get confused if it connected to No.2 or No.3 and impact the quality of service.

The user device connects to the one physically nearest. So for example, a Vodafone tower has two cell antennas out the top broadcasting the Vodafone signal across an area, which will overlap to a small degree. A user’s device will always want to make sure it is connecting to the same one. You don’t want to connect to one antenna and back to another – It’s this that ruins the quality of service. So you will always try and connect back to the one you were talking to, which is normally geographically the one closest to you. 

The Physical Cell ID is used to identify each space. We don’t want those numbers to overlap too often, or our devices get confused and don’t know which to connect to. If a device can see a Physical Cell ID of 2, and there’s another cell antenna using an ID of 2, it wouldn’t know which one to communicate with.

It is beneficial to know that 5G-NR has more PCI’s available in the planning stages, to enable a higher quality of service (QoS) for end user devices.



The Robustel R5020 5G Router

We’ve talked a lot in recent weeks about 4G broadband and how it can solve many Wi-Fi issues in rural areas and homes with a slow BT Openreach connection.

But of course, the question on everyone’s lips when we talk about 4G routers and mobile broadband is ‘when will there be a 5G router?’

One product we’re feeling particularly excited about is the Robustel R5020. This router is touted to be offering next-generation cellular connectivity at a competitive price.

The R5020 will enable rapid deployment of high speed IoT applications in sectors such as Transportation, Enterprise Connectivity and Digital Signage.

In a compact industrial unit, the R5020 will offer 3G, 4G/LTE and 5G band coverage.

What are the key features?  

Here are the key features of the Robustel R5020 5G router.

A router with 5G capability

As Robustel’s first 5G capable router, the R5020 will also be capable of supporting 4G and 3G bands.

 

A stable operating system

Powered by their tried and tested CPU platform, the R5020 uses their mature and stable in-house Operating System RobustOS. This OS is fully programmable with a fully documented Software Development Kit. It also comes with a free cloud management platform (RCMS).

 

Applications

The R5020 is designed for use by various applications.

In-vehicle applications

  • Passenger Wi-Fi
  • CCTV de-brief
  • Ticketing
  • Other similar “onboard” requirements

Potentially increase internet speeds in these scenarios with the R5020, as well as future-proofing your current installations by making them 5G compatible. The R5020 has achieved E-Mark* certification for in-vehicle use, and supports GNSS (Global Navigation Satellite System) positioning. There is also a version to protect vehicle batteries with vehicle ignition sensing when the engine is turned off.

Broadband Failover

  • As well as a 5G Router, the R5020 can be configured to use Ethernet or Wi-Fi as the primary internet source. Should there be an outage on either of these, it can then failover to 4G or 5G.
  • If your business is a shop or small office, this can provide a good degree of connectivity resilience at a reasonable cost.
  • It can provide sufficient bandwidth for multiple users.
  • Core networks can utilise connections from IPSEC (Internet Protocol Security), DMVPN (Dynamic Multipoint VPN) and Open VPN (Virtual Private Networks) protocols.

Primary Broadband

  • You might think that using mobile broadband would be a pricey alternative, but mobile networks are now offering unlimited 5G tariffs at reasonable prices.
  • This means that hundreds of Mbps internet are available over the air.
  • There are many technical and commercial scenarios that make a wireless internet connection a favourable option, and mobile broadband offers another level of connectivity on top.
