In this paper, we give an overview of the evolution of wireless mobiles starting from the first generation which is the analogue system started in 1980’s, and passing through the 2G technologies which are all digital networks and GSM is the most popular network. 2.5G networks will introduce the packet notion on the existing 2G networks and 3G will bring the quality of service as new perspective for the 3G partnership projet 3GPP and 3GPP2. However, high demand on data speed has pushed the operators to looking for 3.5G system. 3.99G networks are defined as long-term evolution for the existing 3G network and it will be based on OFDM and MIMO technologies. 4G networks was not yet defined, but requirement is to support heterogeneous networks at 100 Mbps mobility data speed

This paper covers most aspects of LTE Radio Frequency (RF) system planning; this study has been extended to cover different implementation scenario for LTE-Advance. It explains the parameters that comprise the 4G cellular RF Link Budget and the basic propagation models in order to perform a RF Planning for LTE. Cell coverage has been estimated for different spectrum band and bandwidth and different modulation and coding schemes (MCS).
