A brand new generation of mobile phone standards has made an appearance roughly every tenth year since 1G systems were introduced almost 30 years ago Or 1982. Each generation is indicated by new frequency bands, greater data rates and non backwards compatible transmission technology. The very first discharge of the 3GPP Long-term Evolution (LTE) standard doesn’t completely match the ITU 4G needs known as IMT-Advanced. First release LTE isn’t backwards suitable for 3G, but is really a pre-4G or 3.9G technology, however sometimes top quality “4G” through the service companies. Its evolution LTE Advanced is really a 4G technology. WiMAX is yet another technology verging on or promoted as 4G.
