At lunch I was browsing through some old email and was reading some "help me learn about OLSR" type conversations.
There was a link to the book; Wireless Networking in the Developing World
Its now in second addition and in now translated to more languages, you can download it or buy it.
It has been a while since I have setup up new WiFi infrastructure. My network at home has been pretty stable. I should go see whats new in the second edition...
