MTS increased the speed of data transmission from the subscriber to the Network to record 50 Mbps

MTS company together with Qualcomm and Huawei conducted the test run of the new capabilities of LTE technology. In particular, due to the aggregation frequency data transmission rate of the reverse channel increased to 50 Mbit/s This speed allows you to upload a 20 minute HD video on YouTube in about two minutes.

MTS held a demonstration of new capabilities of the fourth generation cellular communication (4G) standard LTE. Testing was performed in Vladivostok, jointly with the supplier of networking equipment Chinese Huawei and chipsets manufacturer American Qualcomm, says Cnews.

In the experiment was shown the possibility of the aggregation of frequencies (carrier aggregation) for uplink data (uplink). Russian operators, including MTS, are already using carrier aggregation for the incoming data feed (download) ā€” aggregated frequency bands 2.6 GHz, 1800 Gmts and 800 MHz. This approach allows to significantly increase the speed of data transmission.

But with the growing popularity of social networks and services such as Instagram and Periscope, there is an increasing demand of mobile subscribers and high speeds for uplink. To this end, the MTS aggregated 10 MHz of frequencies in the 2.6 GHz band with 5 MHz of frequencies in the 1800 MHz band. Both bands used the technology of frequency division for uplink and downlink ā€” FDD.

Another novelty is the use of a new type of modulation. Now LTE uses a modulation of 64 QAM for downlink and 16 QAM for uplink. In these same tests were used for downlink modulation 256 QAM for uplink 64 QAM. Finally, the technology has been applied spatial encoding MIMO 4Ɨ4, suggesting the use of four antennas for reception and for transmission.

As a result, in the course of a demonstration test speed uplink channel up to 50 Mbps. In ordinary circumstances the speed of outbound channel is up to 25 Mbit/s. Technology will be particularly popular among owners of smartphones and tablets, leading online translation, gamers, bloggers, and users that copy large amount of data in the “cloud”.

In the incoming same channel speed up to 150 Mbit/s While the download has not been applied to aggregate bandwidth. In the case of its application the velocity would have increased to 250 Mbit/s In normal conditions the speed of this channel is up to 70 Mbps.
