Evolution of telephone network was similar to t.v. broadcasting in 1946 with push to talk system. First generation comes with advanced mobile phone system and regulations on bandwidth, frequency, modulation and multiplexing. Second generation, based on global system for mobile communication, became digital from existing analog first generation system, which made possible short messaging services and internet with voice communication. GSM was evolved to general packet radio service by changing circuit switched system to both circuit and packet switched system for voice and data respectively. For live data with voice and multimedia, universal mobile telephone service, wideband code division multiple access were developed as third generation telephone network, by evaluating base station to radio access network and GPRS support nodes. Fourth generation was packed switching based with voice over internet protocol and data in long term evolution. The circuit and packet switched system was evolved into evolved packet core and RAN into evolved node B, in LTE as a main system that was in direction of 4G recommendations of 3GPP was in release 8 to release 11.
