WiMAX is one of the hottest broadband wireless technologies around today. WiMAX systems are expected to deliver broadband access services figure 1 shown below to residential and enterprise customers in an economical way.

Loosely, WiMax is a standardized wireless version of Ethernet intended primarily as an alternative to wire [1] technologies (such as Cable Modems, DSL and T1/E1 links) to provide broadband access to customer premises.

More strictly, WiMAX is an industry trade organization formed by leading communications, component, and equipment companies to promote and certify compatibility and interoperability of broadband wireless access equipment that conforms to the IEEE 802.16 and ETSI HIPERMAN standards.

WiMAX technology provides the equivalent of broadband speeds without the need for cables, and [ 2] service coverage can extend over an entire city, region or even a whole country.

Access to the WiMAX wireless service is subject to a monthly subscription and it requires the use of a dedicated WiMAX modem, which is usually supplied for free by the operator.

The WiMAX family of standards concentrate on two types of usage models a fixed WiMAX usage model and a mobile WiMAX usage model. The basic element that differentiates these systems is the ground speed at which the systems are designed to manage.

Based on mobility, wireless access systems are designed to operate on the move without any disruption of service; wireless access can be divided into three classes; stationary, pedestrian and vehicular.

A mobile WiMAX network access system is one that can address the vehicular class, whereas the fixed WiMAX serves the stationary and pedestrian classes. This raises a question about the nomadic wireless access system, which is referred to as a system that works as a fixed WiMAX network access system but can change its location.
