By using WiMAX technology the authors can overcome the limitations of the existing wireless communication like short coverage area, lack of security and low data rate. WiMax has become a hot spot for global telecom operators and manufacturers. In 1998, a working group named 802.16 was formed by the Institute of Electrical and Electronics Engineers (IEEE), and their responsibility is to develop the specifications of broadband wireless access technology.
