International Journal of Electronics and Communication Engineering. ISSN 0974-2166 Volume 6, Number 1 (2013), pp. 1-8 © International Research Publication House Comparision of 3G Wireless Networks and 4G Wireless Networks: 1 Arun Kumar, 2 Suman and 3 Renu 1 Lecturer, ECE, Eiilm University, Jorethang, Sikkim 2&3 Perusing M.Tech., HCTM College, Hrayana Abstract By examining the two papers on 4G and 3G, namely wireless networks: opportunities and challenges by Hassan Gobjuka, Verizon, 919 hidden bridge irving, Tx 75038 and wireless network: opportunities and challenges emphasis us to throw light on the differences between the two networks. This task is being done in order to list out the drawbacks and merits of these two evolutions of the networks and further to implement R&D research to bring out their sparks in this modern era. The differences are done on the following Index terms: Background difference, definitions, technologies progress, speed/ rate of transmission, switching technologies used, network, band width, design specification, QoS, service and billing, features and capabilities. Keywords: RAN, SONET, UTRAN, FLASH OFDM, CORE NETWORK,SGSN 1. Introduction: 3G is also called third generation. It is named as such because it is the third generation of the standards of telecommunication hardware. It is also the general technology for mobile networking, passing the recent 2.5G. The technology is founded on the ITU or International Telecommunication Union group of standards which belongs to the IMT-2000. 4G is the fourth generation of mobile phone mobile communications standards. It is a successor of the third generation (3G) standards. A 4G system provides mobile ultra-broadband Internet access.
