3G Network in Moscow to test frequencies of GSM.

State Commission for Radio Frequencies has allowed the operators to test 3G network in Moscow at frequencies 900/1800 MHz, writes the newspaper Kommersant. These frequencies are currently employs conventional GSM-network. For 3G, typically using 2.1 gigahertz frequency.
MTS and VimpelCom "(brand" Beeline ") emphasize that problems with the construction of networks of third generation mobile communication frequencies 900/1800 MHz will not arise. In particular, the 3G network at a frequency of 900 MHz are already working in Finland.
Australian operator Optus in 2007, tested the 3G network at a frequency of 900 megahertz. As a result, the operator has concluded that such a format is best suited for sparsely populated regions, as well as the coverage of one station operating at 900 megahertz, is much broader than that of the station, which operates at a frequency of 2.1 gigahertz.
Representatives of Qualcomm emphasize that the 900-megagertsevye advantage of 3G networks and in the cities. The construction of two identical networks of 3G base stations operating at 900 megahertz, will be required in 2,2 times less than the stations operating at a frequency of 2.1 gigahertz.
The representative of Vympelcom "reported the newspaper" Vedomosti "that the construction and testing of the network in Moscow 3G, operating at a frequency of 900/1800 MHz, will take six months. ITT expects to test and deliver the Moscow 3G network into commercial operation a year and a half. Plans "megaphone" in Moscow on the construction of 3G networks in the 900/1800 MHz frequency range are not reported.
There are fears that the network is 3G, operating at 900 megahertz, can lead to overloading of conventional networks GSM, operating on the same frequency. As a consequence, the quality of connection deteriorates.
At present, MTC, Vympelcom and MegaFon have 3G networks in more than a dozen of Russia's regions. They work on a standard frequency of 2.1 gigahertz. In Moscow, the frequency is occupied by soldiers.
In January, reported the successful completion of interoperability testing at frequencies of 3G networks and structures of the Ministry of Defense in the Moscow subway. Network 3G, operating at a frequency of 2.1 gigahertz, will appear in the Moscow subway by the end of 2009.
