The rollout of the UK’s future 5G mobile network must be handled better than 4G was, according to a new report.
The current 4G network ranks only 54th in the world in terms of coverage, a panel of government-appointed experts has said.
The National Infrastructure Commission (NIC) said there must be far fewer dead spots the next time round.
Ofcom welcomed the report but indicated the study that gave rise to the ranking might not be reliable.
The communications regulator’s targets are based on the percentage of properties that have access to a mobile phone signal rather than coverage to all parts of the country.
But the figure quoted by the NIC was based on data gathered by an app used by volunteers measuring the amount of time they had access to a 4G network as they travelled about.
“We agree that mobile coverage must improve, so we’re pleased the NIC shares our ambition for universal coverage,” said a spokesman for the communications regulator.
“Our rules mean that virtually all UK premises must receive a 4G signal by the end of next year, and we’re also making more airwaves available to boost mobile broadband.
“Last month, we challenged mobile operators to explore how to reach all remote areas and transport lines.
“We will shortly publish robust data on 4G in the UK, to help inform decisions on improving coverage.”
A 5G standard does not yet exist, but the technology is expected to surpass 4G to provide faster data uploads and downloads when it is deployed, some time after 2020.
The NIC said mobile connectivity had become a “necessity” in society and 5G would play a crucial role in the economy.
“The market has driven great advances since the advent of the mobile phone, but government must now play an active role to ensure that basic services are available wherever we live, work and travel, and our roads, railways and city centres must be made 5G-ready as quickly as possible,” the report said.
Quoting research by the mobile data crowd-sourcing firm OpenSignal, the NIC attacked the UK’s 4G coverage ranking.
“The UK’s networks are not complete. There are too many digital deserts across the country and the availability of our 4G network is worse than many countries including Albania, Panama and Peru,” the commission said.
Its report called on the government to become a “digital champion” by, for example, creating a dedicated cabinet minister.
Roadside networks needed to be made “fit for the future”, while the railway network must “rapidly improve connectivity”, it said.
The necessary infrastructure for both should be in place by 2025, the report said.
The NIC predicted the need for tens of thousands of small wireless cells in towns and cities for devices to connect to the 5G network.
The idea is that these would have less range than the current mobile phone masts, but there would be more of them and they would be better positioned to ensure blanket coverage.
The report called on local authorities to work with network providers to make this possible.
The commission said the government and Ofcom must “ensure basic outdoor mobile services are available wherever we live, work and travel”.
It said the two bodies should develop a “meaningful set of metrics that represent the coverage people actually receive and use these to determine a mobile universal service obligation setting out the minimum service level people should expect to receive”.
Regulation in this area must “keep pace” with the rapid evolution of the mobile communications markets, in order to allow new firms to “provide services that the existing market has not delivered”, the report added.
