 what is perhaps the most important operating scale for wireless networks - the local area network. Building on the introductory description of Part I, local area wireless networking technologies are reviewed in more detail - including the full alphabet of 802.11 standards and enhancements. The practical aspects of wireless LAN implementation are then described, from the identification of user requirements through planning, pilot testing, installation, configuration and support. A chapter is devoted to the important topic of wireless LAN security, covering both the standards enhancements and practical security measures, and Part III closes with a chapter on wireless LAN troubleshooting. Part IV - Wireless PAN Implementation - takes a similar detailed look at wireless networking technologies on the personal area scale, including Bluetooth, wireless USB, ZigBee, IrDA and Near Field Communications. The practical aspects of wireless PAN implementation and security are covered in the final chapter of Part IV. Part V - Wireless MAN Implementation - looks at how the metropolitan area networking challenges of scalability, flexibility and quality of service have been addressed by wireless MAN standards, particularly WiMax. Non-IEEE MAN standards are briefly described, as well as metropolitan area mesh networks. Introducing Wireless Networking The practical aspects of wireless MAN implementation are discussed, including technical planning, business planning and issues that need to be addressed in the start-up and operating phases of a wireless MAN. Part VI - The Future of Wireless Networking Technology - looks at four emerging technologies - namely wireless mesh routing, network independent handover, gigabit wireless LANs and cognitive radio - that, taken together, look set to fulfil the promise of ubiquitous wireless accessibility and finally lay to rest the recurring technical challenges of bandwidth, media access, QoS and mobility. Finally Part VII - Wireless Networking Information Resources - provides a quick reference
