Switzerland’s largest mobile operator and fixed line incumbent, Swisscom, has signed a five-year contract with Swedish vendor Ericsson to update its wireless network and a future upgrade to Long Term Evolution (LTE) technology. Under the terms of the agreement, Ericsson will modernise 6,000 mobile sites with its RBS 6000 multi-standard radio base stations and optimise all of Swisscom’s networks. The rollout will start in January 2012 and is due to be completed by end-2014. As noted in TeleGeography’s GlobalComms Database, Swisscom began testing LTE technology in Grechen in October 2010, followed by the subsequent rollout of trial networks in Davos, Grindelwald, Gstaad, Leukerbad, Montana, Saas Fee and St Moritz/Celerina in November this year. The cellco intends to deploy the 4G technology in the country’s busiest tourist areas and high demand zones such as city-centres, but is awaiting the distribution of LTE concessions, due to be completed in early 2012, before announcing any concrete deployment plans.
