MTS was tested in a commercial network technology Ericsson HSDPA Multi-Carrier 3 Carriers, which allows us to aggregate the three carrier frequencies on the 3G network. Peak data rate during the tests rose by a third, to 63 Mbps.
Aggregation of the three carrier frequencies width of 5 MHz was carried out in the range of 2.1 GHz. What is the number of base stations (BS) were used to test the technology was not specified.
“Today, more than 90% of base stations MTS third generation are working on technology DC-HSDPA+ with the use of two carrier frequencies, providing a peak data rate of up to 42 Mbit/s At 64% of base stations to DC-HSDPA+ in 83 regions of the Russian Federation included the third carrier, which can be used to zoom in on the third network capacity or to increase the access speed to 63 Mbps. Other 3G base station operator with one carrier work on HSPA+ technology with speeds of up to 21 Mbps,” according to the MTS.
In MTS said that the third carrier is included in the Moscow region and some regions of Central Federal district on the equipment of Nokia, in most regions of far East Federal district – on the equipment of Huawei. “Various vendors provide the ability to enable their equipment to a third carrier in 3G. We are not talking about a replacement technology DC-HSDPA+ with the third carrier, which, depending on the region being used on the equipment of Huawei or Nokia, solution Ericsson. HSDPA Multi-Carrier 3 Carriers can be applied where we work on Ericsson equipment – in the Volga, Urals, southern, North Caucasus, northwestern Federal districts. As well as in several regions of the Siberian Federal district”, – said Dmitry Solodovnikov.
In the future, according to Vice-President of MTS on technology and it Andrei Ushatsky, 4G, more advanced technology, will gradually replace 3G. “But we go by evolution, not artificially spurred by a generational change. Today, the standard of the third generation is still in demand. The share of 3G devices in the hands of our subscribers is 38%, and about 68% of the total data traffic of our subscribers to have 3G, said Andrew Ushatsky. – Therefore we continue to modernize 3G networks.
2014 MTS includes in various regions of Russia at the base stations 3G third carrier. The growth speed of access base stations of the third generation from 42 Mbps to 63 Mbps allows to speak about the approximation characteristics of this standard to the speed of the fourth generation.
Another operator of the “big four” “the Megaphone” spent testing the technology, which unites three carriers in different standards, in the past year. “In the end we came to the conclusion that it is much more promising and more profitable to combine the three carriers in the 4G. The consolidation of the three carriers in the 4G allows you to reach speeds of 450 Mbps, and it is somewhat more 63 Mbps available on 3G,” he told the ComNews reporter the head of the press service of the company.
“We are studying the possibility of using aggregation three bearing taking into account the technological and economic components”, – said the press-Secretary of “Beeline” Anna Imasheva. She added that this network functionality supports at the moment a limited number of subscriber devices.
Tele2 currently uses the aggregation of the three carriers and negotiations on this issue does not conduct, said the company.
