Abstract
Ever since mobile technology standards were first laid down in the 1980s (the First Generation or 1G), there has been a continuous effort to increase the data rates available to the end users. Higher levels of data rates are achieved by the industry by the Mobile Communication Technologies with the increasing demand of the users. While connecting to internet, the speed of internet is depends upon the signal strength that has been shown by the alphabets like G, E, 2G, 3G, H, H+ and 4G right next to the signal bar on the home screen of mobile. The key technologies that have made it possible are MIMO (Multiple Input Multiple Output) and OFDM (Orthogonal Frequency Division Multiplexing). The two important 4G standards are WiMAX (has now fizzled out) and LTE (has seen widespread deployment). It is the generation on which academia and the industry both are working and expected to arrive in 2020. In addition, the main purpose of the fifth generation wireless networks (5G Wireless networks) is planned to design the best wireless world that is free from limitations and hindrance of the previous generations.
