Russia’s three largest mobile operators by subscribers, Mobile TeleSystems, Vimpelcom and MegaFon, have been given permission to launch outdoor 3G services in Moscow, Reuters reports. As reported by CommsUpdate on 12 December 2008, while the service has been available in areas across the country for some time the relevant wireless spectrum has been reserved for military use, the release of which has faced multiple delays. With spectrum tied up, operators have instead had to make do with limited networks confined to indoor areas such as airports, train stations and other buildings. Now that the frequencies have been vacated operators are free to build out their networks to provide an exterior service. Vimpelcom received permission to erect 1,000 transmitters, while MTS plans to set up 783 transmitters and MegaFon will establish 700 this month and later increase this to more than 3,000. Though the companies have received permission from the Roskomnadzor Federal Supervision Agency for Information Technologies and Communications to set up the transmitters, they still need approval from a range of municipal authorities before launching services. The firms are expected to continue with the rollout, however, and will start to deploy the technology immediately.
