5G in the UK: Two networks offer the fastest speed and best coverage

To see exactly how the networks are performing, what speeds to expect and the extent of coverage, I toured the UK to test 5G in five major cities: London, Cardiff, Birmingham, Manchester and Edinburgh. The next-generation wireless technology promises a big boost in speed and responsiveness, bringing not just a faster connection to your phone, but also enabling advancements like telemedicine and self-driving cars. The UK deployment is among several happening worldwide from the US to South Korea, as 5G slowly turns from hype to reality. EE and Vodafone have the largest UK networks so far, while O2 and Three are ramping up. I visited the cities across the course of a week, seeking out a variety of locations in each place that showed as 5G-enabled zones on network coverage maps.
