Mobile communication is one of the hottest areas with advanced techniques. It is developing extremely fast in present times and deals with all the fields of mobile and wireless communications. This paper deals with the comparative study of wireless cellular technologies. First Generation, Second Generation, Third Generation, Fourth Generation and Fifth Generation are comes under wireless cellular technologies. A cellular network or mobile network is a radio network distributed over earth areas called cells. Each cell is served by at least 1 fixed-location transceiver and transceiver is known as a cell site or base station. In a mobile network, each cell uses a different set of frequencies from other neighboring cells and avoids interference. The First Generation was referred as cellular and which was later abbreviated to “cell”. Cell phone signals were analog in nature. 1G device was comparatively less heavy and expensive. Second Generation mobile phones used GSM technology. Global System for Mobile communications uses digital modulation and it improves voice quality with limited data service. The Third Generation allowed mobile telephone customers to use voice, graphics and video applications. Fourth Generation is for cell phones or/and hand held devices. The fifth generation wireless 5G development is based upon 4G, which at present is struggling to meet its performance goals. Most important advantages of 5G network is providing myriads of services to end users. The importance of this paper is to study a speedy and effective network connection for communication of devices.
