This book covers mobility with WiMAX and Wi-Fi. This rigorous tutorial provides the technical guidance needed to design and integrate Wi-Fi and Wi-MAX into existing 2.5 and 3G wireless systems. 3G Wireless with 802.16 and 802.11 makes manageable the in-demand design and re-engineering tasks involved in adding Internet and broadband capabilities to existing wireless phone networks. Look inside for the engineering specifics you need to: design and integrate 802.16 into RF systems; configure Wi-Fi for fixed wireless delivery; integrate Wi-Fi into mobile wireless systems; integrate WiMax and Wi-Fi into a mobile wireless system; and, learn 802.20 design parameters.Written by hands-on communications engineers, this remarkable guide clearly shows you how to approach the many issues confronting designer/integrators, including: an introduction - from Wireless Mobility Concept to Fixed Wireless (LMDS, MMDS), and 802.X Radio Engineering, from Generic Radio Systems to Bi-Dimensional Amplifiers Network Engineering, from Basic Switching to the Backhaul Digital Wireless Systems, from Enhancements over Analog to 2.5G/3G 2.5G/3G Integration with Wi-Fi and WiMax 802.1 1, from Hotspots to VPNs, SOHO, and More 802.16, from RF Design Considerations to Integration with 802.11/Mobility 802.20 and Integration with 802.11 and 2.5G/3G Convergence Wireless Mobility, including Various User Devices, and Smart Switches 4G.
