The Russian CDMA-450 mobile operator SkyLink has won another GSM-900 concession, this time in the republic of Chechnya. The operator, which recently won GSM spectrum in government spectrum auctions covering Siberia and the Far East, intends to overlay its existing CDMA-based networks with GSM infrastructure to widen its appeal. SkyLink’s Chechnyan division has also been awarded GSM-1800 frequencies, as has Svyazinvest subsidiary Nizhny Novgorod Sotovaya Svyaz (NSS), CNews reports. Chechnya is currently home to two GSM operators: MegaFon, which counts around 400,000 active subscribers in the republic, and Vimpelcom, which launched its first network there in September and is targeting 100,000 users within six months. The region has a population of approximately 1.2 million and with poor fixed network coverage cellular services are seen as a major growth area.
