Air Interface: Air interface requirements (T21)

Abstract

IEEE 802.16™ is an emerging suite of standards for Broadband Wireless Access (BWA). IEEE Std 802.16e, amendment to the IEEE 802.16 base specification, enables combined fixed and mobile operation in licensed frequency bands under 6 GHz. This combination of IEEE Std 802.16 and the 16e amendment, here forth referred to as IEEE 802.16-2004&E [Ref 1, 2], is designed as a high-throughput packet data network radio capable of supporting several classes of IP applications and services based on different usage/mobility and business models. To allow such a diverse combination of usage, mobility, and deployment models, the IEEE 802.16-2004&E air interface is designed with a high degree of flexibility and an extensive number of options. To ensure interoperability and certification of WiMAX Forum Certified™ products, system profiles and PICs need to be developed within the WiMAX Forum™.
This document provides functional, performance, and operational requirements for a family of air interface profiles that optimize the system performance for mobile performance while supporting other usage
scenarios.
The end-to-end Network Requirements for WiMAX networks are separately defined in “Recommendations and Requirements for Networks based on WiMAX Forum CertifiedTM Products” [Ref 5].
