MTS announced the launch of its LTE network on 1800 MHz in St. Petersburg in addition to the existing network of the fourth generation in the frequency range of LTE 2600. C the launch of the network of LTE service became available to owners of smartphones iPhone 5.
Now LTE “Beeline” not only uses the frequency range 2600 MHz and 1800 MHz. At the moment the operator’s network covers the southern part of St. Petersburg, including Nevsky, Frunzensky, Moskovsky, Kirovsky and Krasnoselsky districts, Pushkinsky and Kolpinsky districts. Out of town LTE-1800 present in Vsevolozhsk and Lomonosov districts of the Leningrad region. “Tens of thousands of new users LTE”, – noted in MTS.
According to the operator, the extra range allows you to expand coverage, through expanded coverage areas of base stations, and to improve the quality of the connection, including in buildings.
After running this network, LTE services become available for users of iPhone 5, cell modems, which up to this point did not support the Russian network of the fourth generation. In addition, the signal of LTE-1800 penetrates better indoors, improving the quality of 4G coverage in homes, schools, large stores and other city buildings.
Work LTE in the 1800 MHz band, originally allocated for GSM, can negatively affect the quality of voice communication, fears of the technician of one of the companies of communication. The allocation of spectrum for data transmission narrow bandwidth, which employs the GSM phones (2G). To LTE-1800 worked efficiently, the desired band width of at least 5 MHz, in addition to her voice bands should separate protective strip, said the source. The 3G network can compensate for this loss of frequencies, but only partially: when it is overload the phone will still switch to 2G, even 3G is still not supported by all phones, he warns.
In MTS deny the possibility of deterioration of voice quality. The reduction in the range of 1800 MHz compensates for not only 3G network but also rescheduling the network, which will enable us to move more voice traffic on the GSM base station operating in the 900 MHz range, explains the operator: the part of subscribers who started to use the Internet in the LTE-1800 will the release of the 3G frequency, so the speed in the third generation network will grow. Avoiding the use of 1800 MHz band — this is a strategic preparing to migrate the voice network LTЕ.
