WiMax?
WiMax (IEEE 802.16) promises better than 10 miles service radius with higher bandwidth, better encryption, and better Quality of Service (QoS) management than WiFi. Deployment cost is estimated at $10/person for better than 90% coverage in most countries, depending on population distribution, terrain, weather, and other issues. However, there are no large WiMax deployments yet, even though some are planned or in early trials. Some in the industry claim that it is too soon for any country-wide rollouts due to immaturity of the standard and its implementations in products.
Do we have any WiMax experts?

Make sure you decide in advance what kind of internet access you will have in the schools. If you will use a wireless access point make sure to test it and in particular test it with the number of XOs which will be using it to connect to the internet.
