heading up the implementation of 5g is ruth spencer, who took me on a tour to show me some of the newsites that will underpin what will be a radical new infrastructure. ag to 5g is going to be a massive step change in infrastructure. so, for example, in ag, what you would have had before is big masts, quite long—distance parts... covering a large area. whereas with 5g, particularly in urban areas like this, you'll need lots of small cells very close together. that's a massive infrastructure challenge, isn't it, if you need lots and lots of masts to cover a city. i think what we're trying to do at the moment is understand how cost—effective that it is going to be to deploy at this kind of level. it sounds like a massive ask. is it realistic? it is a big undertaking. but the potential that 5g is going to unlock is going to be completely transformative. now, the problem is the 5g signal is very fragile, easily blocked by trees and buildings and that means that ruth's team has had to produce really detailed surveys of where the antenna need to be. whenever you put a new building up, it in
