Ukrainian engineers scramble to keep mobile phones working during war

With Ukraine scrambling to keep communication lines open during the war, an army of engineers from the country's phone companies has mobilised to help the public and policymakers stay in touch during repeated Russian missile and drone strikes.

The engineers, who typically go unseen and unsung in peacetime, often work around the clock to maintain or restore phone service, sometimes braving minefields to do so.

After Russian strikes took out the electricity that cellphone towers usually run on, they revved up generators to keep the towers on.

I know our guys my colleagues are very exhausted, but they're motivated by the fact that we are doing an important thing, Yuriy Dugnist, an engineer with Ukrainian telecommunications company Kyivstar, said after crunching through 15 centimeters of fresh snow to reach a fenced-in mobile phone tower on the western fringe of Kyiv, the capital.

Dugrist and his co-workers offered a glimpse of their new daily routines, which involve using an app on their own phones to monitor which of the scores of phone towers in the capital area were receiving electricity, either during breaks from the controlled blackouts being used to conserve energy or from the generators that kick in to provide backup power.

Stopping off at a service station before their rounds, the team members filled up eight 20-litre jerrycans with diesel fuel for a vast tank under a generator that relays power up a 50-metre cell tower in a suburban village that has had no electricity for days.

It's one of many Ukrainian towns that have had intermittent power, or none at all, in the wake of multiple rounds of devastating Russian strikes in recent weeks targeting the country's infrastructure power plants in particular.

Kyivstar is the largest of Ukraine's three main mobile phone companies, with some 26 million customers or the equivalent of about two-thirds of the country's population before Russia's Feb. 24 invasion drove millions of people abroad, even if many have since returned.

The diesel generators were installed at the foot of the cell phone towers since long before the invasion, but they were rarely needed.

Many Western countries have offered up similar generators and transformers to help Ukraine keep electricity running as well as possible after Russia's blitz.

After emergency blackouts prompted by a round of Russian strikes on Nov. 23, Kyivstar deployed 15 teams of engineers simultaneously and called in all our reserves to troubleshoot the 2,500 mobile stations in their service area, Dugrist said.

He recalled rushing to the site of a destroyed cell tower when Russian forces pulled out of Irpin, a suburb northwest of Kyiv, earlier this year and getting there before Ukrainian minesweepers had arrived to give the all-clear signal.

The strain the war is putting on Ukraine's mobile phone networks has reportedly driven up prices for satellite phone alternatives like Elon Musk's Starlink system, which Ukraine's military has used during the conflict, now in its 10th month.

After widespread infrastructure strikes last week, Ukrainian President Volodymyr Zelenskyy convened top officials to discuss the restoration work and supplies needed to safeguard the country's energy and communication systems.

Special attention is paid to the communication system, he said, adding that no matter what the Russia has in mind, "we must maintain communication.
