For the past couple of weeks, I've been testing Vodafone's new 5G network in London. My aim was to see how it compares to 4G service, I'm a long-time Vodafone subscriber, and to get a feel for the experience end-users can expect from 5G as coverage is deployed more widely and densely. A secondary aim was to learn what Vodafone's deployment can tell us about mid-band 5G.
