Mobile operator Telia Norge and Swedish vendor Ericsson have initiated a 5G New Radio (NR) TDD-FDD carrier aggregation (CA) for coverage extension trial in Lillestrom, a municipality in Viken county. In a press release regarding the matter, Ericsson claimed that, with the trial being undertaken ‘as part of Telia’s ambition to bring nationwide 5G coverage to Norway by 2023’, CA would enable the cellco to maximise its existing spectrum and extend coverage in the mid-band frequencies (3.6GHz), boosting capacity and increasing peak throughput for faster data speeds. Initial test results from the CA trial were said to have shown an increase in 5G coverage of over 50% in the 3.6GHz band.
Meanwhile, alongside outlining details of the trial, the pair said they were already making progress toward the former’s coverage targets, noting that they expect to deliver 5G connectivity to 19 more cities across Norway by mid-2021, with 50% of the country projected to have coverage by the end of 2021.
Commenting, Espen Weum, Acting Head of Infra, Telia Norge: ‘We are very proud to together with Ericsson be the first in the Nordics to successfully test 5G carrier aggregation. With this new technology, our mobile and FWA customers will experience enhanced capacity, coverage, and speed on our fast-expanding 5G network. We will begin to roll out carrier aggregation in our network as soon as we have completed the ongoing testing phase.’
