Description

This is not another book about installing a home or “hobby” Wi-Fi system. Instead, this book shows you how to plan, design, install, and operate WLAN systems in businesses, institutions, and public settings such as libraries and hotels. In other words, this book is packed with serious information for serious professionals responsible for implementing robust, high performance WLANs covering areas as small as a coffee shop or as large as entire communities. Ron Olexa provides a solid foundation in RF/wireless theory as it applies to WLANs. His detailed, thorough coverage of propagation at GHz frequencies helps you understand the mysteries of WLAN coverage (such as how it can change from season to season due to foliage). You’ll also learn about antenna radiation patterns and gain so you can design you WLAN to have the coverage you need without causing interference to (or suffering interference from) other WLANs.

Key Features

  • Covers the widely used 802.11 family, as well as the new 802.16 and 802.20 standards
  • Focuses on big commercial network implementations, such as in public buildings and businesses
  • Author has over 25 years of experience with cellular systems and wireless networks

Readership

RF/wireless design and applications engineers; networking engineers. Electronics engineering students.
