This fall’s massive NATO exercise in Norway known as Trident Juncture can interfere with both mobile phone and DAB radio signals. It’s unclear whether the country’s communications network will meet the demands placed on it.
The NATO exercise will involve 40,000 soldiers from all 29 NATO countries plus Sweden and Finland. Norwegian defense officials have ordered more than 1,300 SIM cards for the occasion, and state-owned mobile phone provider Telenor can’t rule out ill effects on both DAB and mobile signals.
“The network may fail and there can be incidents that put the mobile network temporarily out of service,” Bjørn Amundsen, in charge of coverage for Telenor, told state broadcaster NRK. “But we have boosted preparedness, and I think things will go well.”
Telenor is especially concerned for the area around the Rygge air base in Østfold, south of Oslo, and around the military base at Sessvollmoen near Gardermoen. Mobile phone service provider Telia is also boosting preparedness by setting up extra base stations to help handle the increased mobile network activity.
