Best practices for planning and deployment of broadband WWANs.
Learn insider tips from an experienced wireless industry leader
Understand the principles that underlie the operation of all wireless systems
Learn how to provide profitable and reliable wireless Internet access
Select the most effective equipment and antenna systems for your area
Avoid common pitfalls encountered by new wireless network operators
Minimize the effects of noise and interference on your network
Enjoy the satisfaction of providing wireless Internet access to your community
Practice the business principles used by successful wireless ISPs (WISPs)
Use 802.11a, 802.11b, and 802.11g equipment more successfully in your own home, office,
or outdoor environment
Choose the right network architecture for your wireless network
Conduct physical site surveys and radio-frequency (RF) site surveys
License-free broadband wireless wide-area networks (WWANs) provide fast deployment of low-
cost, high-speed "last-mile" wireless Internet access. License-free wireless technology delivers
these benefits without requiring the use of products or services provided by local telephone or
cable companies. WWANs enable Internet service providers (ISPs) and corporate IT managers to
deploy their own cost-efficient broadband networks that deliver high-speed access for buildings
and areas where traditional wired connectivity is either completely unavailable or is cost-
prohibitive. Deploying License-Free Wireless Wide-Area Networks is the first book that provides
complete, real-world "start-to-finish" design, installation, operation, and support information for
wireless ISPs and other organizations deploying outdoor wireless WANs-including coverage of
802.11a, 802.11b, 802.11g, and proprietary-protocol networks. This vendor-neutral book covers
all brands of broadband wireless equipment and explains the principles upon which all wireless
equipment is based. Inside, you'll find step-by-step instructions and crystal-clear explanations
that walk you through initial planning stages and onto full wireless network operation. End-of-
chapter review questions reinforce important concepts.
Whether you're an IT director, ISP engineer, network architect, or field technician, Deploying
License-Free Wireless Wide-Area Networks is your essential reference. With practical, in-depth
coverage of the real-world challenges of outdoor, license-free wireless WAN deployment, this

License-free broadband wireless wide-area networks (WWANs) provide fast deployment of low-
cost, high-speed "last-mile" wireless Internet access. License-free wireless technology delivers
these benefits without requiring the use of products or services provided by local telephone or
cable companies. WWANs enable Internet service providers (ISPs) and corporate IT managers to
