ABSTRACT Fourth generation wireless carcass is a packet switched wireless system with enormous theater of operations coverage and high throughput. It is designed to be cost high-pressure and to provide high spectral efficiency . The 4g wireless go fors extraneous Frequency Division Multiplexing (OFDM), Ultra Wide wireless telephone (UWB),and Millimeter wireless.

Data rate of 20mbps is employed. Mobile travel rapidly give be up to 200km/hr.The high performance is achieved by the use of long term channel prediction, in some(prenomin al) time and frequency, scheduling among use! rs and smart antennas combined with adaptive diversity and indicator control. Frequency band is 2-8 GHz. it gives the ability for world wide roaming to annoy cell anywhere. 1.
