Abstract
The requirements are growing up way very faster networking system limitations of the current up data system. Have forced the research to come up with more than, the current approach effective technology is the next step in this direction, 4G is the generation of 4 level wireless network. It is the very faster 4G networkbetter on service more than facilities, with better service. 4G it about are it s generate global network that will be able to provided. Technologies each capable of performing function like supporting voice traffic using voice environment etc.., The developing 4G network system more than advantage 4G network system better on 4G presents a solution of this problem as it is all about harmonics integrating network application. The race to implement 4G is quite challenging. The aim of this paper is to highlight the benefits challenges in development & scope of 4G network.
