October 9, 2012 at 21:28Yota Launched Real 4G: LTE Advanced
Today, October 9, Yota Networks held a press conference to launch LTE Advanced , the latest iteration of the LTE standard. It is interesting that this version of the standard, along with WiMAX 2, can be called 4G, and the LTE networks operating around the world at the moment are not a real 4G, but a marketing one .
And although Yota became the first company in the world to introduce a new standard on a commercial basis and offer it to its virtual operators, the first devices with its support in Russia will appear only in the first half of 2013. Yota explains this decision with a simple desire to speed up the process by first creating a proposal and then demand: the earlier the networks appear, the earlier the user devices that support LTE Advanced will appear.
Currently, data transmission via LTE Advanced is supported by 11 base stations in Moscow. The company's tests showed speeds of up to 300 Mbit / s on a subscriber device with a theoretical limit of 1 Gbit / s.
It is also interesting that the transition from LTE to LTE Advanced requires a simple software update and further setup of the base stations, as well as the addition of processor cards to some of them. In the future, to use, for example, the MIMO 8x8 functionality, it will be necessary to replace or install additional radio modules, but the implementation of the new standard will not require a complete rebuild of the entire network.
Subscriber LTE devices do not need replacement; the standard supports backward compatibility. However, to take advantage of LTE Advanced, a device with support for it is required.
From a technical point of view, the main advantage of the technology is the possibility of combining carriers, both from one and from different frequency ranges into a single band. So Yota Networks, having 2 carriers of 15 MHz each, can get a single band of 30 MHz, which will at least double the maximum speeds on subscriber devices and improve signal quality due to more efficient radio resource control mechanisms within one wide band.
