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.
