EE turned on the UK’s first 5G network today, across London, Edinburgh, Cardiff, Belfast, Birmingham, and Manchester. 5G connectivity is now available in limited parts of these cities, more than a month before rival Vodafone plans to launch its own 5G service. I took to the streets of London today to test out 5G, armed with a OnePlus 7 Pro 5G handset. I’m impressed with the early results.

While 5G coverage has been extremely limited with Verizon’s 5G network in the US, it’s a whole different story in London. EE has focused its initial coverage on popular tourist destinations across London, including areas like St Paul’s, Covent Garden, Soho, The Strand, Tower Bridge, and London Bridge. I visited a number of different locations today and performed speed tests against both the 4G and 5G networks of EE.

Now, I know these 5G networks aren’t being fully utilized right now, but the average speeds were still a 10x improvement over what I was seeing on 4G. I’d say the average I was seeing was around 200 Mbps on 5G, compared to around 25 Mbps on 4G in the same spot. I didn’t have to stand in a very precise location to get a 5G signal most of the time, and I was able to walk freely along The Strand, into Covent Garden, and even into London Charing Cross Station all while connected continuously to 5G. The best speed I recorded in this area was around 510 Mbps, close to the popular area of Covent Garden during the peak lunch hour.

5G speeds in London seem to average around 200 Mbps

Most of my testing was performed outside, but I even managed to test the 5G signal inside a lunch spot and Charing Cross Station. Inside a Pret a Manger, I was averaging around 60 Mbps, compared to the 200 Mbps outside the building. But inside Charing Cross Station, I saw speeds of 200 Mbps. I even took a train from Charing Cross Station through to London Bridge, and the 5G signal was maintained for part of the journey between Waterloo East and far outside of London Bridge. Even with the train moving, I was consistently hitting speeds in excess of 200 Mbps, and at one point when it was moving slowly, this jumped all the way up to 980 Mbps.

The worst part about this current 5G implementation is that upload speeds are the same as 4G right now. The max I hit during my testing was a measly 33 Mbps, which is far from the average of 200 Mbps down. That’s the most disappointing aspect of EE’s 5G network for me so far, alongside the limited coverage. EE is promising to add 100 cell sites per month and that download speeds should be between 100 to 150 Mbps quicker on 5G than 4G. There’s no promise on upload speeds, though.

I’ve only managed to test the network for a few hours today, but that was enough to drain the phone’s battery from 50 percent to nothing on just speed tests alone, using a mixture of the Fast app and Ookla’s Speedtest app. I’m planning to spend the next week testing out this 5G network in various locations and getting a good idea of latency, too. The promise of 5G isn’t just about the bandwidth improvements alone; it’s also about the latency improvements for activities like streaming games from the cloud.

Much like using a 1 Gbps connection at home, it’s hard to measure the benefits of 5G right now. Yes, everything naturally loads faster, but it feels like I’m using a really good Wi-Fi connection. The most practical benefit I immediately noticed was being able to stream 1440p HDR content through YouTube and easily scrubbing to any section of the video instantly. It’s these little things that count in the short term, but apps and services have been built to cache and load balance this very carefully for years. That means not all services even have the capacity to meet your connection and transfer data as quickly as your device can handle.

5G could be a genuine leap for connectivity

While many people will be skeptical about why speeds like 980 Mbps are needed on a phone, the practical benefits are far-reaching. If we can reach reliable gigabit speeds on 5G networks, then this opens up the ability for new applications, cloud streaming of 4K and above content, cloud game streaming, augmented reality games beyond even Minecraft Earth, and much more. There’s even talk of everything from your dishwasher to a lamp post being connected up to 5G, but the near-term practical benefits will allow you to work anywhere reliably.

3G allowed for sharing of photos and some video streaming and calls, and 4G made this even faster and video streaming far more reliable. 5G promises to bring significantly faster speeds and much lower latency. We’re at the early stages of deployments of 5G right now, in what has become a silly race. But like any technology, it will improve over time. 5G in the UK is launching initially on sub-6GHz frequencies, which are good for more coverage, but they don’t have all the benefits that 5G promises. Higher frequencies allow for more bandwidth to be passed to devices, but they operate over a smaller distance, and the radio waves can’t easily penetrate walls and objects that are in between you and the 5G antenna.

This will be a particular challenge once 5G in the UK moves toward the millimeter wave (mmWave) spectrum. This promises far better speeds than I’ve tested today but with the challenges of shorter transmission ranges that can be tricky when there’s no direct line of sight and interference from walls, buildings, or even rain.

Early adopters of 5G will pay the price

Radio waves aside, the other 5G challenge will be operators and their data pricing. Prices for EE’s 5G plans start at £54 ($68) a month for 10GB of data, rising to £74 ($93) a month for 120GB. With faster speeds, it’s far easier to be tempted to use a 5G connection with your laptop and start downloading far more data like you would on a home fiber connection. You could realistically use 120GB of data within minutes, making 5G an expensive gamble for early adopters.

Early adopters of 5G will also have a very limited option of handsets. EE is launching with OnePlus’ 7 Pro 5G as the exclusive handset for around a week. OnePlus has been working closely with EE to optimize its handset for the new 5G network, and although the 5G handset looks and feels exactly like a OnePlus 7 Pro, the company has done a lot of work internally to improve the antenna arrangement.

Samsung’s S10 5G, Oppo’s Reno 5G, and the LG V50 ThinQ will also be available in June. Huawei’s Mate 20 X 5G hasn’t made the list just yet, as EE has paused the launch of it after Google pulled the company’s Android license in response to a US government ban. We’re still waiting to see a lot more 5G-enabled devices, and it looks like Apple won’t bring 5G to the iPhone until next year.

It’s obviously early days for 5G in both the US and UK, but I’m planning to spend a week testing out what’s possible to get a better idea of what we can realistically expect from 5G in a busy city like London. Check back next week for the results.
