The specification of fourth generation mobile communications (4G), known under the name Long Term Evolution (LTE), finally finalized, said the other day a representative of standardization of 3GPP wireless. In its final version of LTE will provide the speed of incoming connection 326 Mbit / s when using 20- MHz bandwidth. The maximum rate of outgoing connection is set to 86 Mbit / s.
Recall that such a significant increase in bandwidth allows the use of multiple two-way technology transfer (MIMO), similar to that of Wi-Fi protocol 802. 11n. Latency is reduced to 10 milliseconds, which will use LTE for sensitive response time services such as video calls and online gaming.
The news of the completion of the specification came shortly after a recent successful demonstration of the relation of the 4th Generation by Nokia, in which the urban environment has been achieved data rates of 173 Mbit / s. It is obvious that the simultaneous use of equipment by several thousand subscribers, the real rate may be even lower.
It is expected that LTE will be the foundation of mobile internet in Europe and the U.S. over the next few years. For example, U.S. AT. European part of the project will, Vodafone.
