Nokia Siemens Networks (www.nokiasiemensnetworks.com) (NSN) is claiming that it has launched the “world’s first commercial HD voice GSM network” with its MegaFon deployment. Needless to say, HD Voice News has requested clarification on the statement, but it appears that service is being delivered on both 2G and 3G networks.
The MegaFon HD voice deployment was initially reported in November 2010, with service delivered to Moscow. Today’s NSN/MegaFon announcement lists Moscow and Sochi – home of the 2014 Winter Olympics – as having HD voice service, using AMR-WB as the codec.
According to the Wikipedia definition of GSM, there are a number of GSM frequency bands for 2G and 3G service. The press release notes that MegaFon is providing HD voice on both GSM and UTMS networks; thereby implying both 2G (GSM operation) and 3G (UTMS) service delivery.
To date, previous commercial HD voice deployments have typical been on shiny new 3G/HSPA+ networks. If NSN is delivering services on existing 2G/legacy networks, this would indeed be a world “first.” In comments to HD Voice News, HD voice leader Ericsson had suggested 2G would be the next path for wideband voice deployments.
Previously,NSN had announced it had provided the gear for Orange Armenia’s network modernization – including support for HD voice and HSPA broadband delivery — in a December 2010 press release. There’s also a January 31, 2011 “Customer Success” story claiming Tata DOCOMO as a NSN customer and supporting 3G and HD voice.
