Telia is building 5G cell towers for the battlefield

Tank behind her, a young woman dressed in combat fatigues sports an incongruous-looking pink smartphone on a muddy road somewhere in Ukraine. Named Dasha, she is a practitioner of BYOD (bring your own device), a phenomenon normally observed in the office rather than on the battlefield. At one time, her Ukrainian military superiors would probably have confiscated the smartphone and given her a device built for the army to work on the army’s own technology. But those days are gone.

“That is her main means of communication and with it she can communicate not only with friends and family but also with her fellow soldiers, with civilian ambulances and towing trucks to clear roads,” said Henning Huuse, a manager of 5G business development at Telia Norway, who screened an image of Dasha during a presentation at Informa’s Future Enterprise Networks Event in London this week. “Cellular networks are very resilient,” he added. “Basestations can be shot one by one but it’s difficult because they are spread all over the country.”

Such considerations explain why Norway’s own armed forces approached Telia about two years ago, asking for a service based not on proprietary technology but on the same 5G standard used by civilians. Their requirements for performance, security and reliability sounded familiar to Huuse, who had already worked on the development of private 5G networks for non-military enterprises. By ringfencing a part of Telia’s public 5G network to provide service guarantees – a process known as network slicing – Huuse believed Telia could satisfy the demands of Norway’s armed forces just as it would those of a typical client.

He turned out to be right. A unit called Telia Tactical Networks does now manage a 5G slice for the Norwegian armed forces, roping off sensitive data and providing service guarantees. On top of that, Telia has been developing a portable kit, in partnership with its suppliers, to provide connectivity for military operations.

Portable networks

Two mock-ups of movable cell towers were shown at Future Enterprise Networks. The larger one uses the same 5G antenna from Ericsson that would typically feature on rooftops in city centers. At the base of the tower, a black box hosts a battery as well as various computing resources. Those include Ericsson’s radio access network software and a full “core” network designed by Athonet, an Italian vendor recently acquired by HPE. It is, essentially, a complete 5G network, providing connectivity over a radius of about five kilometers.
