Reading thru your e-mail, there are two vectors - the backhaul (interconnecting schools) and local network (interconnecting the laptops). The backhaul technologies can be independent of the local network. They could be the same as well. For example the MIT roofnet could possibly do both - there are 400mW wireless cards (MP-8602, http://www.yawarra.com.au/pdfs/XC-MP-WFabg-400.pdf) which have a span of ~40 km for backhaul, with directional antennas, of course. (I do not have the links, let me know if you couldn't find them) Got to run ... Hopefully I have answered some of your questions ... Do not hesitate to ask questions as you think thru the various aspects of the network like line of sight, what is in between et al.

Oliveira Sent: Wednesday, November 08, 2006 8:13 AM To: [email protected] Subject: [OLPC Networking] Wireless Mesh tests Hello everybody, I and a group of volunteers are creating an wireless network to interconnect the schools in our city, we are at this moment in a testing period trying to figure out witch technology to use (Wi-Fi, Wi-Max, Motorola canopy...) but one important goal of this project is to be compatible with the OLPC laptops. In the laptop.org Wiki I have founded this http://wiki.laptop.org/go/Wireless saying: "There is new firmware with mesh routing support" and that the chip Marvell 88W8388 is compatible with the 802.11b/g great! But my question is: The mesh feature needs some different equipment to support it? I mean in the radio-base section is it necessary to have some different thing than a 802.11b/g radio? When will the Laptops be available to test the wireless network features? I really would like to make some tests with it in my area. I do not intend to keep it with me for too much time, I just need to test it so I would put 2 or three of it working and after the tests would deliver it back to anyone who needs to test it too. Greetins from Brazil Sorry for my poor English Thank you all ---------------------------------------- Tadeu F.
