What is WiMAX?
|
| WiMAX or the Worldwide Interoperability for Microwave Access is an emerging technology that is designed to deliver fixed and mobile broadband connectivity. The WiMAX term is used to group a number of certified wireless technologies that have emerged from the IEEE, ETSI and the WiMAX Forum. This section introduces the WiMAX technology and lists the key players in its development. The drivers for WiMAX adoption are reviewed for the three main network configurations; Fixed, Mobile and Mesh. WiMAX is compared and contrasted to other wireless technologies such as Wi-Fi and the cellular technologies HSDPA/HSUPA and LTE. The section also explores the WiMAX Network Architecture and introduces the three key network elements; Terminal Equipment, ASN (Access Service Network) and CSN (Connectivity Service Network).

The WiMAX Radio Interface
|
| OFDM (Orthogonal Frequency Division Multiplexing) and OFDMA (Orthogonal Frequency Division Multiple Access) and increasingly being used in many radio systems to significantly improve performance in non line of sight scenarios. The section introduces the fundamental principles of these multiplexing techniques and in so doing explains what is meant by the terms Fast Fourier Transform a Cyclic Prefix. The section also briefly introduces the five defined physical layers before concentrating on the two key variants - OFDM and OFDMA. The section concludes by reviewing the licensing issues affecting WiMAX and the various implementations currently in operation throughout the world. Finally the strategies behind WiMAX radio planning are briefly introduced for both Fixed and Mobile configurations.

WiMAX Initial Procedures
|
| The initial procedurs used to establish a connection within the WiMAX network are not dissimilar to many wireless architectures. This section charts these procedures and in so doing, introduces the various messages which pass across the radio interface and on towards the ASN and CSN. The section begins by reviewing the scanning and ranging procedures prior to describing the significance of the basic capability information exchange. The section also explores the security mechanisms supported by WiMAX for both fixed and mobile configurations. IP Address allocation methods are explained along with a brief description of how internetwork connectivity may be supported by Mobile IP. The terms Quality of Service and Service Flows are then explained before relating their significance to the various supported media flows.

WiMAX Operation
|
| WiMAX provides subscribers with a broadband IP connection in order to interface with a wide range of multimedia services. This section briefly explores the WiMAX functions which are used to support the transer of information across the end-to-end architecture for both fixed and mobile configurations. It then goes on to explain the additional issues effecting mobile WiMAX networks such as Idle Mode, Power Control and Sleep Mode in addition to the many handover methodologies. The section concludes by briefly reviewing the WiMAX Mesh configuration and discussing how this mode of operation may be supported within typical deployments.
