Ad hoc works well for very small groups (6) -- and in that case you want them all to be in the same channel... to be able to communicate! :-) It's for the under a tree scenario, no access points around. If there is a lot of interference, it means there are lots of APs. Just make one AP available to the XOs ;-) m -- martin.langh...@gmail.com mar...@laptop.org -- Software Architect - OLPC - ask interesting questions - don't get distracted with shiny stuff - working code first - http://wiki.laptop.org/go/User:Martinlanghoff ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
Ad-hoc networking - automatically selecting the best channel
My understanding is the Sugar's ad-hoc automatically defaults to channel 1. Would it be possible for the client (XO or otherwise) to automatically pick the best channel (1, 6 or 11) based on prevailing interference levels?

Re: [Sugar-devel] Ad-hoc networking - automatically selecting the best channel
How would you propose measuring interference levels, and how long would this measurement be allowed to take? The measurement would delay the setup of the ad-hoc network on the laptop. The measurement would require the participation of another node in the ad-hoc network. If another node is not available, how long should the laptop wait before giving up on the measurement? -- James Cameron http://quozl.linux.org.au/ ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
