(Section "Spectrum Management at 5 GHz (802.11h), p. 160"). As a result, the previous support for HiperLAN/2 in the European industry has virtually disappeared. Given the overwhelming industry focus on products based on the 802.11 suite of standards, it seems unlikely that HiperLAN/2 will ever establish a foothold in the wireless LAN market, the clearest indication of this being perhaps that Google News returns zero hits for HiperLAN/2! Summary Since the ratification of 802.11b in July 1999, the 802.11 standard has established a dominant and seemingly unassailable position as the basis of WLAN technology. The various 802.11 specifications draw on a wide range of applicable techniques, such as the modulation and coding schemes shown in Table 6-18, and continue to motivate the further development and deployment of new technologies, such as MIMO radio and the coordination and control functions required for mesh networking. As future 802.11 Task Groups make a second pass through the alphabet, the further enhancement of WLAN capabilities will no doubt continue to present a rich and fascinating tapestry of technical developments. Chapter 6 has provided a grounding in the technical aspects and capabilities of current wireless LAN technologies. Chapter 7 now builds on that foundation in describing the practical considerations in implementing wireless LANs. This page intentionally left blank CHAPTER Implementing Wireless LANs There are many routes that lead from the identification of a user requirement for wireless networking to the operation and support of an installed WLAN, and the best approach to be taken will depend on the nature and scale of the project. In this chapter a five-step process is described that is scalable from a simple ad-hoc home network to a large scale corporate WLAN, linking multiple buildings. In small scale projects, such as in implementing a typical home or small office WLAN, some of these steps will be very short or may be eliminated altogether. Nevertheless, an awareness of the issues addresse
