The "True" 4G Technology
However, so-called 4G technologies, including LTE (Long Term Evolution), WiMAX (Worldwide Interoperability for Microwave Access) and UMB (Ultra Mobile Broadband), are just networking service projects proposed to ITU (International Telecommunication Union) to be defined as 4G technologies. To be accorded the official designation of 4G, the transmission speed has to reach the requirement of 100Mbps (mobile networks) and 1 Gbps (fixed networks).
So far the above so-called 4G technologies have not yet fully complied the transmission requirements of 4G standard, and should be called 3.9G, or pre-4G technologies, ITU noted.
ITU has received six technology submissions and is currently in the evaluation process for determining which can be qualified as true 4G technology. The determination will be made in October 2010, according to ITU's earlier announcement.
