(Worldwide Interoperability for Microwave Access) WiMAX has evolved as one of the most effective techniques for providing last mile connectivity for Wireless Systems. It is a technology which is developed to promote and certify interoperability and compatibility of broadband wireless access and standardizes as IEEE 802.16. The WiMAX is very similar to WiFi but it provide higher data rates compared to WiFi and also it can be used over greater distances and for greater number of customers. There are several features of WiMAX that are responsible for the effectiveness of WiMAX systems. This paper introduces the fundamentals of the system with previous work done on the system.
