Hello, welcome to the programme and today we want to get you excited by the next generation of mobile technology.

Some of us can remember when 3G seem to be the future.

Well, we're now all settled comfortably on 4G and the mobile operators in the UK

have just bid over a billion pounds for chunks of radio spectrum at a recent auction

to enable them to roll out

5G from 2020, possibly even earlier. How does it differ from 4G? We'll hear about that. And this is a

conversation that'll take us from mobile phones to cars and fridges and the so-called internet

of things. I've got three guests, all trained engineers, who know all about 5G.

In fact, are busy testing it's already.

So let's just meet them before we get stuck in.

Derek McManus, Chief Operating Officer at Telefonica, UK, which owns O2.

Where does O2 rank in the Mobile League at the moment in the UK?

O2 is a brand ranks number two after E.

Telefonica when you add up all of it is actually the biggest network in the UK.

Right. What do you mean when you add up all of it?

So if you take GIFGaf, Tesco Mobile, and we also have association with companies like Sky. So customers

who use our network, there's more customers using the O2 Telefonica network than there is

any other network. Gotcha. Now, in April, there was this big auction of the 5G licenses. How did

O2 do? How much did you pay? And how was that whole process? So we did very well. We won the largest

slice of the spectrum that was up for auction. The spectrum came in two parts. I'll get slightly

technical. There was a part that's called 2,300, which is available now. And we won all of that. So we can

use that now to bring benefits to customers in old 4G
