Abstract : Mobile communication is the fastest growing field to provide mobile Internet to the users. The increased usage of social networking sites and multimedia applications on the Internet requires tremendous bandwidth. There are various techniques evolving in mobile and wireless communications for offering high data rate, reliability, long coverage, and high mobility to satisfy the need of high quality of service to the users. To provide Internet anytime from any network, global roaming, and high quality of service to the users, 4G is being deployed in most of the places by some operators. While other operators are also planning to start the deployment of 4G. Since the some operators are deploying fourth generation networks, the other operators are also in the need to move 4G networks. But there are many operator has been invested a huge amount on third generation networks as well as migrating from 3G to 4G technology is not easier. This paper reviews the technical challenges in moving from 3G to 4G and also suggests complementary services for the network operators for quick deployment to offer high data rate and highly reliable services. It concludes with the performance analysis of 3G and 4G network in terms of quality of service that can deliver. © Research India Publications.
