Wireless Networking in the Developing World: A practical guide to planning and building... (Repost)

This book was created by a team of individuals who each, in their own field, are actively participating in the ever-expanding Internet by pushing its reach farther than ever before. This book documents our efforts to build wireless networks in the developing world.
IN THIS EXPANDED SECOND EDITION, YOU WILL LEARN HOW TO: Build a wide-area wireless network using inexpensive 802.11 wireless networking equipment; Share a common Internet connection between many sites; Determine the economic feasibility of your network project; Understand the basics of radio propagation, including environmental effects, transmission lines, and antenna characteristics.

This book is about building low-cost wireless network infrastructure. In it you will find information about:
• Design and construct a solar power system for remote communications sites
• Implement every step needed to build a functioning wide area community wireless network, including feasibility and capacity planning, equipment selection, installation, monitoring, and ongoing maintenance
• How to design a wireless network that extends the reach of an existing Internet connection
• Understanding radio waves, antennas, and transmission lines
• Choosing and configuring wireless networking hardware
• Designing a solar energy system to provide power to network devices in remote places
• Securing, monitoring, and maintaining your network
• Implementing an economic model that will sustain your project
