State-owned telecoms giant Rostelecom has announced that it has switched on Long Term Evolution (LTE) base stations in Krasnodar and Sochi, as part of an extensive 4G trial ahead of the 2014 Winter Olympics. The tests have so far generated downlink transmission speeds of 63Mbps, with Rostelecom optimistic that it will see download speeds reach 80Mbps before the trial is over. Approximately 100 LTE base stations are expected to be installed in the two areas by the end of the year. The telco has confirmed that the trials have utilised frequencies in the following spectrum bands: 791MHz-820МHz, 821MHz-862МHz, 2530MHz-2620МHz and 2650MHz-2690МHz.
Rostelecom, along with mobile giant MegaFon, was named as a general partner for the 2014 games back in 2010, and the two companies went on to stage a successful joint LTE trial in August 2010 at the Roza Hutor ski resort in Krasnaya Polyana, Sochi. The area was selected because of treacherous conditions and inhospitable mountain terrain.
