IEEE 802.16 Medium Access Control and Service Provisioning
نویسندگان
چکیده
In this paper we describe the IEEE 802.16 Orthogonal Frequency Division Multiplexing (OFDM) and the 802.16 Orthogonal Frequency Division Multiple Access (OFDMA), Medium Access Control (MAC) protocols, both of which are key elements of the Worldwide Interoperability for Microwave Access Forum (WiMAX) deployments. We also discuss the types of provisioning and Quality of Service (QoS) that can be achieved using the features of this MAC protocol to facilitate the WiMAX deployments. Finally, we review the challenges inherent in implementing this MAC protocol on architectures such as the Intel IXP network processors and embedded Intel architecture processors to support the application of MAC functionality to the wide range of potential QoS and provisioning approaches.
