To achieve a successful broadband wireless access solution, the IEEE 802.16 subcommittee has released a series of standards for WiMAX (worldwide interoperability for microwave access). From a technical viewpoint, WiMAX is a feasible alternative to the wired Internet access solutions such as cable modem and DSL. Nevertheless, from the commercial viewpoint, whether the promise of WiMAX will be materialized still depends on its revenue rate to telecom operators and its service quality to the subscribers. In such a context, this article addresses two resource management mechanisms in WiMAX access networks, that is, adaptive power allocation (APA) and call admission control (CAC), from the perspectives of both service providers and WiMAX subscribers. APA emphasizes how to share the limited power resource of base station among different WiMAX subscribers and further influences the access bandwidth of each subscriber; CAC highlights how to assign a subscriber's access bandwidth to different types of applications. Moreover, to build a WiMAX access network, APA and CAC have to work cooperatively to provide cross-layer resource management. In this article we focus on the OFDMA-TDD system, which allows high spectrum-utility efficiency on uplink and downlink channels in the asymmetric scenario of "lastmile" Internet access. We conclude the article with an optimization strategy to balance service provider's revenue and subscriber's satisfaction
