Abstract Wireless last mile technology is becoming a challenging competitor to conventional wired last mile access systems like DSL and cable modems or even fiber-optic cables. The European Telecommunications Standards Institute (ETSI) and the Institute of Electrical and Electronics Engineers (IEEE) have lately developed a new standard for fixed broadband wireless access systems in frequency bands below 11 GHz. This paper gives a short overview of the IEEE 802.16a/OFDM, respectively ETSI HiperMAN standard. The medium access control (MAC) and the physical layer (PHY) are described. An initial system performance analysis of an example scenario is performed. Further on, the MAC packet data unit (PDU) configuration is analyzed. The two optional features packing and fragmentation are evaluated. An optimal MAC PDU length is calculated in the presence of rest bit errors. Especially the interaction of fragmenting MAC PDUs and the padding of orthogonal frequency division multiplex (OFDM) symbols is evaluated in detail. It is shown that the options packing and fragmentation are powerful to optimize the system throughput. A prototypical IEEE 802.16a protocol stack has been implemented into a simulator by utilizing the specification and description language. Based on the event-driven simulator, downlink and uplink delay as well as throughput evaluation is performed. Thus, performance results based on meaningful MAC configuration examples are provided. These results are compared with previously obtained analytical results.
