Description:

This book describes how to plan, implement, and troubleshoot wi-fi network systems using all standards—the widely used 802.11 family and the new 802.16 and 20—for public, industrial, and commercial applications, such as waiting areas, conference rooms, libraries, offices, public spaces such as coffeehouses, etc. This is not a "home networking" or "personal wi-fi" guide, but instead a book aimed people who need (for example) to implement a wi-fi network.

 

Table of Contents:

Introduction; High speed Wireless Data standards;
Radio and RF Basics: Receiver, Transmitter, Antennas, Modulation, Shannon information theory and its effect on receiver sensitivity and EbNo, RF Channelization,RF Link budget, Acceptable path loss,
Frequency reuse; Propagation basics: Radio wave propagation above 2 GHz, Multipath and it's effects,
Fading, Terrain and morphological considerations, Line of sight, free space and non-line of sight paths and their unique effect on path loss and attenuation; Propagation modeling and measuring:
Simple modeling techniques, Complex computer modeling techniques, Site surveys and measurement; System Planning: Determine available products, Determining capacity requirements, Determining coverage requirements,Point to point,Multipoint Antenna selection and location, Frequency planning,
Interference management,Backhaul,Network requirements, Costs; System implementation, testing, and optimization: RF planning, Central equipment (routers, gateways and firewalls), Internet access facilities, Equipment selection,
Construction, Testing and optimization, Monitoring and management; Troubleshooting: Coverage holes,
Interference, Area variables, Capacity,Throughput;
Back office systems: Billing,Customer care,Tech support,Trouble ticket management, Order entry and financial; Software CD: Path loss spreadsheets designed by Author, Publicly available tools such as Netstumbler and Kismet, Demo versions from one or more purveyors of commercial computer propagation analysis tools.
