Parts of Great Britain now have a 5G mobile network with super-fast data speeds and more reliable connections after years of hype. The service is now available in six cities around the UK and is due to roll out nationwide over the next year. But one major telecoms player could be missing out. CGTN's Juliet Mann reports from London.

"So you see 540, 548, faster than almost anyone can get in their home in the UK."

A self-confessed tech geek, telecoms analyst Ben Wood is excited about the possibilities of 5G - the fifth generation mobile network. With 4G, the UK was years behind other countries when it finally launched in 2012. But Ben says Britain's now leading the way.

BEN WOOD, TELECOMS ANALYST CCS INSIGHT "we've caught up. It's fantastic. We are going to be one of the first places in Europe to have comprehensive 5G capability in major cities and I think it is great for UK plc."

JULIET MANN LONDON "It is busy places like this. Train stations, stadiums, business districts, that will really benefit from 5G technology. That is why EE are rolling out their next generation mobile network in six major UK cities. Rival Vodafone will launch their 5G network in July in 7 major cities."

Coverage will expand nationwide as other providers launch later this year, but to use 5G, you'll need a new handset. Not everyone though is convinced.

"Phone does what I need it to do. Not really in a hurry."

"I'm not too bothered about the 5G especially if you have to pay for a new phone."

"I don't want to pay for an extra phone to upgrade to 5G when you can't get it where I live."

Samsung, LG and HTC all produce 5G handsets. But one major player missing out is Huawei. Google banned the Chinese tech giant's new 5G devices from receiving upgrades on the Android operating system. And the new Huawei 5G phone has been blocked from the UK's first 5G mobile entrants, EE and Vodafone. Huawei may provide some of the UK's new 5G infrastructure but has been shut out of core parts of the system amid security concerns.

BEN WOOD, TELECOMS ANALYST CCS INSIGHT "Missing out on 5G for Huawei was already a challenge from a network perspective, but now it has hit their handsets it is a major blow. The company was on a trajectory to become one of the leading smartphone makers in the word, already number two, hoping 5G would push it to lead new technology in the future and help them truly become a no.1 player."

Many of the innovations that will make 5G truly disruptive are yet to arrive. But providers hope that when they do consumers will be quick to see the benefits. JM, CGTN, London.
