Swedish cellco Tre says it has now achieved full 5G coverage in the centres of seven cities: Stockholm, Gothenburg, Malmo, Norrkoping, Linkoping, Jonkoping and Helsingborg. Meanwhile, it is continuing to deploy 5G infrastructure in cities with more than 20,000 inhabitants, using 2100MHz spectrum and faster 3.5GHz frequencies. The operator has launched a new service dubbed 3Fullfart which uses the 3.5GHz band to offer peak download speeds of up to 1.3Gbps. The service costs SEK49 (USD5.13) a month but is being included free in all subscriptions this year to allow customers to test what Tre calls its 5G+ network. The operator has invested SEK3 billion in the rollout and upgrade of 4G and 5G technology in recent years, with SEK1 billion to be spent in 2022.
