MTS speeds up mobile Internet by combining the two LTE standards
Smartphones in the MTS network will be able to work in a single LTE standard, and in two that provides a significant increase in the speed of your Internet access. This should be the message of the operator.
MTS across all Russia will aggregate frequencies in the 2600 MHz band intended for LTE TDD (time division duplex; for data transmission and reception use the same frequency band) with a frequency of 800 MHz, 1800 MHz and 2700 MHz, which works on LTE FDD (frequency division duplex, when the reception and transmission occur on different lines).
Aggregation of the frequencies tested MTS in Moscow, where her only today TDD-network: the aggregation of its frequencies with LTE FDD in the bands 800 MHz, 1800 MHz and 2700 MHz maximum access speed exceeded 163 MB/s Without aggregation speed when connecting in these ranges was 37-112 Mbps to 112 Mbps was able to accelerate in a TDD network.
Aggregation of FDD and TDD frequencies will also allow MTS to increase the effective area of coverage of TDD in 2.5 times.
The frequency of the 2595-2620 MHz range, allowing to build network TDD across Russia, except for Moscow, the Moscow region, the Crimea and Sevastopol, MTS won the held in February 2016 by Roskomnadzor auction. The operator paid for them of 3.97 billion rubles., offering 35% premium to the starting price.
On TDD network MTS in Moscow now work mainly modems and iPhone, starting with the fifth model and younger, told “Vedomosti” in the company. In the first quarter of 2016 the number of registered devices has increased by 20%. Devices that support aggregation of FDD and TDD, even less. But in the future such devices will become more — their range will grow as well as his time growing spread of LTE devices, I hope in the company.
For example, in Moscow the simultaneous operation of two bands was tested using the Samsung Galaxy S7. The resulting test upload speed to outside reached 165 Mbit/s, indoors – 85 Mbit/s with a maximum of 187 Mbit/S. in addition, the aggregation of frequencies has increased the radius of the base station of LTE TDD by approximately 60% and also improved the quality of signal coverage in TDD environments.
According to analysts, the band of frequencies in the 2600 MHz band, intended for TDD and covering almost the whole of Russia, is a unique competitive advantage MTS and other operators in this scale, this resource is not. For the future it gives MTS a good start to increase the speed of LTE access and expansion of coverage of LTE networks.
