4G or, the Long Term Evolution (LTE) is the fourth generation of mobile telecommunications technology was introduced in 2009. 4G added mobile ultra-broadband internet access to mobile devices in addition to the usual voice and other data services provided by the earlier third generation (3G) technology. The technology enabled high-quality video streaming (up to 1 gigabit per second for stationary users and network latencies of 5 milliseconds) to facilitate gaming services, high definition (HD) videos and high quality (HQ) video conferencing. Service providers that offered CDMA2000 or GSM /UMTS networks used the LTE standard as the upgrade from those earlier, third-generation (3G) standards for faster service.
