WiMAX networks are designed to cover diverse geographic region. WiMAX data range and throughput are higher as compared to 2G/3G networks. A major challenge for wireless network communication is to provide broadband services efficient to everyone. They can cover-up urban areas as well as rural areas. Tx and Rx antennas require for Line Of Sight (LOS) conditions. UL and DL Carrier to INterference Ratio (CINR) are observed. However, in every network it is demanding factor to cover-up the whole region. Relays are introduced within multihop scenarios.
