Purpose: This paper reviews the major technological breakthrough of generations of mobile wireless networks. It discusses the trend of the technology that made robust data services applications, full motion video, video conferencing and Internet access available to mobile users.
Methodology: The research review literatures that reflect the metamorphosis of the mobile communication system. It includes the transition from 1G to 2G, 2G to 3G and the 3G to the latest 4G or the B3G.
Findings \Results: The reasons for the transition to 1G from 0G includes; congestion, limited radio coverage and lack of spare parts and complicated technology. The 1G uses the FDMA designed for voice communication has poor voice coverage and limited radio coverage. This led to the evolvement of the 2G that uses TDMA or CDMA. The limitation of 2G includes the use of circuit switching connection, low data rate and no support for WAP, MMS, SMS, mobile games, search and directories. The 2.5G evolution implements the packet switching technology, given higher data rate and packet data services. It also gives GPRS and EDGE. The 3G provides the support for multimedia applications such as full motion video, video conferencing and Internet access. It uses packet switching technology and basically for higher speed data rate and faster mobile connectivity. The 4G is used to achieve broadband cellular service. It uses IP based services. It is projected towards high speed, high capacity and low cost per bit. It includes mobile TV, mobile virtual network system, mobile search and discovery.
Points to learn: The research provide the knowledge of the history and the evolutionary trends of mobile wireless networks. It revealed the various services provided by each generation for example the 2.5G which provide GPRS. Get information about the technology adopted for each generation i.e. from the era of circuit switching to packet switching and their various limitations for example the 1G with congestion, limited radio coverage and lack of spare parts and complicated technology.
Keywords: Mobile telephony, GSM, GPRS, Packet radio, Telecommunications.
