IMT Advanced

Facilities such as ultra-broadband Internet access, voice over IP, gaming services, and streamed multimedia may be provided to users.

[11] While the ITU adopts requirements and recommendations for technologies that would be used for future communications, they do not actually perform the development work themselves, and countries do not consider them binding standards.

Physical layer transmission techniques expected to be used include:[12] Long Term Evolution (LTE) has a theoretical net bitrate maximum capacity of 100 Mbit/s in the downlink and 50 Mbit/s in the uplink if a 20 MHz channel is used.

In South Korea, SK Telecom and LG U+ have enabled access to LTE service since July 2011 for data devices, slated to go nationwide by 2012.

[citation needed] The first commercial mobile WiMAX service was opened by KT in Seoul, South Korea in June 2006.

[16] In Russia, Belarus, and Nicaragua, WiMax broadband internet access is offered by the Russian company Scartel and is also branded 4G, Yota.

The iBurst technology, using High Capacity Spatial Division Multiple Access (HC-SDMA), was at an early stage considered as a 4G predecessor.

[19] On December 6, 2010, ITU noted that while current versions of LTE, WiMax and other evolved 3G technologies do not fulfill IMT-Advanced requirements for 4G, some may use the term "4G" in an "undefined" fashion to represent forerunners to IMT-Advanced that show "a substantial level of improvement in performance and capabilities with respect to the initial third generation systems now deployed.

Antenna, RF front end enhancements and minor protocol timer tweaks have helped deploy long range P2P networks compromising on radial coverage, throughput and/or spectra efficiency (310 km & 382 km) Notes: All speeds are theoretical maximums and will vary by a number of factors, including the use of external antennas, distance from the tower and the ground speed (e.g. communications on a train may be poorer than when standing still).
