Vacca's new book provides a comprehensive overview of the emerging wireless data technology. The book is geared toward experienced Internet professionals who need to learn how to install wireless networks quickly. It provides numerous hands-on examples, such as an access network protocol, and useful discussions about issues such as the implementation of homeland security (currently most available protocols and products have huge holes). A large portion of the book is devoted to the design of wireless networks, dealing with issues such as standards, robustness, ease of installation and use, and, of course, security. Detailed schematics demonstrate typical filter and uplink applications. The final chapter offers a series of recommendations to support Vacca's assertion that wireless technology is the key to the future of communications and concludes that future networks will require a new methodology that integrates all layers of network design. The book is organized to move from an overview of this emerging technology through the planning and design, installation and deployment, and configuration phases. It also supplies advanced solutions to wireless design problems and new directions of the technology. Altogether a must for those people who are charged with implementing this type of network in their organizations.
