Mobile communication is the two-way communication process in which cellular concept is implemented with frequency-reuse capabilities, digital signal processing, integrated circuits and enhanced battery life. The frequency-reuse concept is dividing the frequency into cells and implement the cells to cover a geographic area ranging from 2km to 50km and outside this range, the same frequency can be implemented. Journey from 1G to 5G: 1G: It is refer as the first-generation wireless communication launched in 1980s and operated at radio signals that use analogue systems such as AMPS(Advance Mobile Telephony system) that use FDM to divide the bandwidth into specific frequencies that are assigned to individual calls. 1G network used to work on 150MHz frequency and up. 2G: It is similar to 1G in frequency range but these types of network used to be operated at digital use either TDMA or CDMA method, instead of analog. The voice during the calls, is encoded to digital and then, transm...
