Kanupriya Singh, Sanjeev Thakur, Somya Singh . Comparison of 3G and LTE with other Generation. International Journal of Computer Applications. 121, 6 ( July 2015), 42-47. DOI=10.5120/21547-4568
In this paper we give an overview of wireless mobiles, starting form first generation (1G) based on analogue system in 1980, while second generation (2G) which sets initial digital standards focuses on capacity and coverage. Emergence of GSM also belongs to 2G. After that third generation (3G) continues with the upgradation and adoption of new technologies such as UMTS-HSPA and CDMA200 EV-DO to provide high speed, low cost and bring the quality in services. Now Long Term Evolution (LTE)technology encompasses the pillars for next generation i. e. fourth generation(4G) for higher throughput, low latency mobile access, multicast and broadcast media and it sets standards for the deployment of 4G around the world. This paper provides a view of these generations and gives a comparative study of 3G and LTE. It also provides some important issues and challenges related to LTE.
