Yota launched real 4G: LTE Advanced
Today, October 9, Yota Networks held a press conference on the launch of LTE Advanced , the latest LTE standard iteration. What is interesting is that this version of the standard together with WiMAX 2 can be called 4G, and currently LTE networks operating around the world are not yet real 4G, but marketing .
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 creating an offer first and then a demand: the earlier the networks appear, the sooner the user devices will appear that support LTE Advanced.

Currently, LTE Advanced data transmission is supported by 11 base stations in Moscow. Tests of the company showed speeds of up to 300 Mbit / s on the 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 tuning of the base stations, as well as the addition of processor cards to some of them. In the future, to use, for example, the functionality of MIMO 8x8 will require replacement or installation of additional radio modules, but the introduction of a new standard will not require a complete rebuilding of the entire network.
LTE subscriber devices will not require replacement, the standard supports backward compatibility. However, to take advantage of LTE Advanced, you need a device with the support thereof.
From a technical point of view, the main advantage of the technology is the ability to combine carriers from both one and from different frequency bands 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 the signal quality due to more efficient radio resource control mechanisms within one wide band.
