Next year worldwide 5G network infrastructure revenue could reach $4.2bn, an 89 per cent increase on 2019.

That’s the prediction made by research and advisory giant Gartner.

It reports that 5G services, already launched in the UK, US, Switzerland, Finland and the UK will continue to roll out worldwide, leading to the increase.

Communication service providers (CSPs) in Canada, France, Germany, Hong Kong, Spain, Sweden, Qatar and the United Arab Emirates have announced plans to accelerate 5G network building into 2020, the report said.

It estimates that 7 per cent of CSPs worldwide have already deployed 5G infrastructure in their networks.

“For 5G deployments in 2019, CSPs are using non-stand-alone technology,” said Gartner’s Sylvain Fabre.

“This enables them to introduce 5G services that run more quickly, as 5G New Radio (NR) equipment can be rolled out alongside existing 4G core network infrastructure.”

“A less robust 4G legacy layer adjoining 5G cells could lead to real or perceived performance issues as users move from 5G to 4G/LTE Advanced Pro,” Fabre said.

“This issue will be most pronounced from 2019 through 2021, a period when 5G coverage will be focused on hot spots and areas of high population density.”
