y that full MIH will provide. Gigabit Wireless LANs The Section "MIMO and data rates to 600 Mbps (802.11n), p. 165" described how the 802.11 Task Group TGn is working towards delivering a PHY layer data rate of 500-600 Mbps, and an effective MAC SAP rate of 100 Mbps, through modifications to the 802.11 PHY and MAC layers and the application of MIMO radio. A number of standards based and proprietary equipment development projects are also underway aiming to deliver a PHY layer data rate of 1 Gbps, a technology threshold becoming known as Gi-Fi that is motivated by a range of home, office and public usage scenarios (Table 14-3). One such effort is the WIGWAM project, which stands for wireless gigabit with advanced multimedia, and was initiated in 2003 by a group of European companies and academic institutions to develop the enabling technologies for gigabit WLANs. The WIGWAM project is industry-driven rather than standards-driven, although the consortium intends to present its results to the relevant standards organisations. Leading Edge Wireless Networking Technologies Table 14-3: Gigabit Wireless Usage Scenarios Usage scenario Description Home usage Multiple concurrent high bandwidth media streaming applications (Video and HDTV) requiring data rates of several 100 Mbps per user. Fast synchronisation of personal storage devices exceeding 100 GB capacity. Office usage Replacing wired Ethernet in supporting high bandwidth office applications such as high-quality video conferencing, streaming media and network file sharing, with the required security and QoS. Public access Short range, very high data rate complement to existing public usage access networks such as GSM, GPRS, Wi-Fi, WiMAX, with seamless media independent handover. High speed Multi-user broadband Internet and media streaming to cars mobile usage and trains, with the additional technical challenge of varying Doppler shifts. The technical challenges faced in reaching this next step in wireless network throughput are familiar from earlier parts of the boo
