MTS SPEEDS UP MOBILE INTERNET BY AGGREGATING TWO LTE STANDARDS

пятница, июня 03, 2016

MTS announces, that it will launch the first fragment of 4G that is an aggregation of spectrum in LTE FDD and LTE TDD standards in Moscow before September 2016 and later in other Russian regions. The aggregation of the two standards will enhance LTE coverage and increase speeds up to 187 Mb/s.

During the testing phase, MTS successfully aggregated the first fragment of its LTE commercial network by combining two carrier frequencies: 10 MHz spectrum bandwidth at the FDD 1,800 MHz standard and a 20 MHz bandwidth at the TDD 2,600 MHz standard. This resulted in increased internet speeds of up to 165 Mb/s outdoors, 85 Mb/s indoors, while the maximum limit was 187 Mb/s. At the same time, the spectrum aggregation directly improved coverage of a LTE TDD base station by 60%, while enhancing the quality of TDD network coverage inside the buildings.

In another set of tests, MTS successfully aggregated three LTE FDD carrier frequencies at the 800 MHz, 1,800 MHz and 2,600 MHz ranges with corresponding spectrum widths of 5 MHz, 10 MHz and 10 MHz. As a result, internet speeds exceeded 163 Mb/s, which is a strong result considering that on a standalone basis the speed would not exceed 112 Mb/s.

Both types of aggregation can work simultaneously, while the system determines automatically the optimal regime depending on network conditions and mobile carrier capabilities.

In Moscow, MTS serves over half of its data traffic over LTE, and the share is steadily growing. The aggregation of FDD and TDD standards will almost double average mobile internet speeds and multiply the effective network coverage of TDD technology by 2.5x. This technique will put MTS customers in a privileged position all over Russia since MTS won a 2,595-2,620 MHz LTE TDD federal spectrum auction in February 2016, while MTS has already been serving Moscow and the Moscow region since 2012 on this LTE standard. Already since the beginning of 2016, the number of LTE-TDD enabled devices has increased by more than 20%.

Development of LTE by MTS

- In Spring 2015, MTS launched a new step towards developing LTE in Russian regions by betting on tech-neutral and multi-range LTE network. To this day, MTS launched tech-neutral LTE-1,800 spectrum in 35 regions and LTE-Advanced with two aggregated frequencies (1,800+2,600 MHz or LTE 800+2,600 MHz) in 25 regions.

- By the end of 2015, MTS was the first Russian telecom operator to launch LTE in all 83 regions where it operated. 

- Since the beginning of 2016, MTS - in cooperation with Cisco – has been implementing a new solution called Cisco SON on its LTE network, which through an automated optimization process can improve internet speeds by 20% on average, enhance network access by 25% and decreases the amount of connection abruptions by 10%.

- Throughout 2015, MTS increased its Moscow LTE network by 50%, while quadrupling the number of indoor base stations.

MTS ENHANCES CAPACITY OF THE MOSCOW - ST. PETERSBURG INTRA-CITY LINE

понедельник, января 28, 2013

MTS has completed modernization of the fiber-optic line between Moscow and St. Petersburg increasing its capacity 10 times from 400 Gb/s up to 4000 Gb/s. This intra-city network is vital for overall operation of the MTS’s mobile and fixed network as it provides for downloading data from many of the internet resources located outside Russia. Whether it’s an MMS sent from London to Moscow, or someone in Nizhny Novgorod watching a clip on youtube, the traffic is likely to go through this channel. Daily traffic in this line already exceeds one Petabyte, a third of total traffic in the MTS intra-city networks. 

 

The increase in the throughput was prompted by the growing pressure on our networks from skyrocketing data traffic. At the end of 2012, our networks were transferring 2600 Terabytes per day, or 200 times the amount of data stored in the Russia’s National Library. Two years from now we expect the penetration of smartphones to rise up to 60%. Proliferation of smartphones, coupled with the roll-out of LTE networks in major cities will trigger annual data-traffic growth of four-five times. Hence, the need to invest in upgrading capacity of intra-city “arteria” that will satisfy the growing demand for data.  

 

MTS’s fiber-optic network already encompasses over 140,000 km of lines. We continue to increase the network by building our backbone and backhaul networks and rolling-out GPON project in Moscow. In 2013, we also plan to enhance the capacity of the Moscow-Yekaterinburg line and conduct modernization of the intra-city lines in the Southern regions in order to increase data traffic exchange with Ukraine, the axis which is also used for data transfer from and to the Western Europe.
