HiperAccess (High-Performance Radio Access)-This is a fixed wireless broadband access network standard. HiperMAN (High-Performance Radio MAN)-This is a fixed wireless access network standard for operating below 11GHz. To ensure harmonization with other similar efforts, ETSI coordinates with the MFA Forum (www.mfaforum.org), the HiperLan2 Global Forum, the IEEE Wire- less LAN Committees 802.11a (http://grouper.ieee.org/groups/802/11/): and 802.16 (http://grouper.ieee.org/groups/802/16/), the IETF (www.ietf.org), the Multimedia Mobile Access Communication Systems Forum (MMAC-PC; www.arib.or.jp/mmacle/), the ITU-R (www.itu.int/ITU-R), and a number of internal ETSI technical bodies. HiperLan2 HiperLan2 will give consumers in corporate, public, and home environments wire- less access to the Internet and future multimedia, as well as real-time video services at speeds of up to 54Mbps. Chapter 15 WMANs, WLANs, and WPANs HiperAccess The HiperAccess standards area creates standards for multimedia BFWA. It was developed to provide a truly broadband system with bit rates of up to approxi- mately 100Mbps, although 25Mbps is expected to be the most widely deployed rate. HiperAccess is targeted at high frequency bands, especially the 40.5GHz to 43. 5GHz band. For these frequency bands, TDMA will be used to provide multiple access. The first BRAN-compliant commercial product-a point-to-point derivative of HiperAccess-was rolled out in December 2004. Numerous operators are showing great interest in HiperAccess, and full HiperAccess-compliant products are becom- ing available. HiperMAN ETSI's HiperM
