TSI) to provide "last mile" fixed wireless access to the small and medium enterprise and residential markets, with the primary aim of accelerating the uptake of broadband Internet access within Europe. The standard has been developed in close co-operation with the IEEE 802.16 Working Group, and is intended to be interoperable with a subset of the 802. 16a standard - namely the OFDM air interface described in Chapter Twelve Table 12-9: HIPERMAN Key Parameters Parameter HIPERMAN standard RF band 5.725-5.875 GHz (European Band C) < 30 dBm (1 watt) Data rate Peak data rates > 2Mbps Modulation OFDM (BPSK, QPSK, QAM) Channelisation 5 MHz, 10 MHz or 20 MHz channel widths Duplex method TDD and FDD are supported the Section "802.11 PHY Layer, p. 310". Table 12-9 shows the key parameters of the HIPERMAN standard. ETSI's intent is to develop a standard which uses unlicensed spectrum, but which can support the commercial provision of fixed wireless access (FWA) based on either point-to-multipoint (PMP) or mesh network configurations. The channel definition is intended to enable at least two competing service providers to cover a metropolitan area, more if the narrower (5 MHz or 10 MHz) channels are used. HIPERMAN defines only the PHY and Link Control layers and, as for 802.16d and the WiMAX Forum, it is anticipated that specifications for the Network layer and higher layers will be developed by other bodies. The equivalent "HIPERMAN Forum" is yet to emerge, but the WiMAX Forum has committed to addressing the issue of interoperability, SO that HIPERMAN is incorporated into the WiMAX standard. The WiMAX forum will effectively fulfil the commercialisation role for both wireless MAN standards. TTA WiBro WiBro, short for Wireless Broadband, is a wireless MAN standard developed by the Telecommunications Technology Association (TTA) of South Korea, Phase 1 of which was approved in November 2004. The standard was developed to fill the gap between 3G and WLAN standards, providing the data rate, mobility and coverage required to deliv
