The short fall of 3G networks is clear‚ it’s just not fast enough‚ offering 384kbps doesn’t meet the requirements of what the end user has come to expect these days. Some people see 3G as a stop-gap‚ until a fully integrated IP network is created; some countries have even chosen to bypass 3G and head straight to 4G‚ a method which has its advantages‚ and its disadvantages II.A. 4G HISTORY At the end of

In 4G technology speed of data is increased up to 100 Mbps for downloading and 50 Mbps for uploading. LTE is advance technology of 3G in which OFDM is used for downloading and SC-FDM is used for uploading of data. In this paper we are understand that what technology already used for mobile communication and why new technology is necessary? And what is the advantage of LTE over GSM
