Book Description
Wi-Fi telephony is the latest, most cost effective, and clearest way of carrying voice data wirelessly. The great news is that it can be integrated seamlessly into the same infrastructures as currently used for computer and telephone data.The digital quality is far above current cellular technologies. This book will be among the first to discuss Session Initiation Protocol (SIP), Quality of Service (QoS), and interoperability in connection with Wi-Fi telephony. Security challenges are also presented and solved along these malleable wireless boundaries. In short, this book provides all the information necessary for effective, reliable, crystal clear Wi-Fi telephony service and implementation. *Using current telephone and computer infrastructure this technology can be implemented at low cost *The importance of Quality of Service (QoS) and security of Wi-Fi telephony is considered *Enhances the clarity of a call beyond a basic cellular phone using digital data transfer

Book Description
'The WiFi Networking Book: WLAN Standards: IEEE 802.11 bgn, 802.11n, 802.11ac and 802.11ax' starts from the ground up for a new user and does a gradual progression into the technical details around IEEE 802.11 Wireless Lan communications standard. The book details the 'legacy' 802.11 stack (a/b/g) and also goes into the latest wave of 802.11 standards - 802.11n, ac and ax. Introduction A wireless LAN (WLAN) is a data transmission system designed to provide location-independent network access between computing devices by using radio waves rather than a cable infrastructure . In the corporate enterprise, wireless LANs are usually implemented as the final link between the existing wired network and a group of client computers, giving these users wireless access to the full resources and services of the corporate network across a building or campus setting. The widespread acceptance of WLANs depends on industry standardization to ensure product compatibility and reliability among the various manufacturers. The 802.11 specification as a standard for wireless LANS was ratified by the Institute of Electrical and Electronics Engineers (IEEE) in the year 1997. This version of 802.11 provides for 1 Mbps and 2 Mbps data rates and a set of fundamental signaling methods and other services. Like all IEEE 802 standards, the 802.11 standards focus on the bottom two levels the ISO model, the physical layer and link layer. Any LAN application, network operating system, protocol, including TCP/IP and Novell NetWare, will run on an 802.11-compliant WLAN as easily as they run over Ethernet.

Book Description
The cell phone is the fastest-selling consumer electronic in the world. On a global basis, over 800 million cellular telephones are sold yearly. More camera-equipped cell phones are sold each year than stand alone digital cameras. Rapid development of new technologies is leading to ever more versatile, multipurpose mobile devices, including 3G Internet-enabled cell phones and PDAs. Meanwhile, wireless networking and wireless Internet access are developing and expanding on a global basis at a rapid rate. Booming technologies include such 802.11 standards as Wi-Fi and WiMax, as well as Ultra Wide Band (UWB) and Bluetooth. Telematics, intelligent transportation systems (ITS) and satellite radio will soon create an entertainment, navigation and communications revolution within automobiles and trucks. Meanwhile, RFID (radio frequency identification) will revolutionize wireless tracking, inventory and logistics at all levels, from manufacturing to shipping to retailing. These developments are creating challenges for legacy companies and opportunities for nimble marketers and managers. Plunkett's Wireless, Wi-Fi, RFID & Cellular Industry Almanac 2008 covers such sectors. Our coverage includes business trends analysis and industry statistics. We also include a wireless and cellular business glossary and a listing of industry contacts, such as industry associations and government agencies. Next, we profile hundreds of leading companies. Our 350 company profiles include complete business descriptions and up to 27 executives by name and title.

Book Description
Wi-Fi has become the preferred means for connecting to the internet - at home, in the office, in hotels and at airports. Increasingly, Wi-Fi also provides internet access for remote communities where it is deployed by volunteers in community-based networks, by operators in 'hotspots' and by municipalities in 'hotzones'. This book traces the global success of Wi-Fi to the landmark change in radio spectrum policy by the US FCC in 1985, the initiative by NCR Corporation to start development of Wireless-LANs and the drive for an open standard IEEE 802.11, released in 1997. It also singles out and explains the significance of the initiative by Steve Jobs at Apple to include Wireless-LAN in the iBook, which moved the product from the early adopters to the mass market. The book explains these developments through first-hand accounts by industry practitioners and concludes with reflections and implications for government policy and firm strategy.
