The development of 5G networking standards is long underway, and a range of different telcos and tech companies are testing and trialling the ultrafast network technology around the world, in a bid to take a bigger piece of the pie.

The UK's capital has also received the support of The City of London Corporation and London boroughs to fund investment towards the city's digital infrastructure.
