[OLPC Networking] [Server-devel] RSSI value questions

[Ryan Crawford Comeaux]

Michael -

Do you think the patent you're referring to would be a significant roadblock
in implementing this system using wifi signal strength measurements?  The
few patents that I've seen (though I haven't been actively searching) seem
to be designed with a system that has a "plurality of receiving stations
with known locations" in mind, which wouldn't affect things here,
considering this would be a system with purely unknown locations.

To everyone reading -

I agree that the XS isn't necessary, though it would allow for more
applications, security being one that was pointed out earlier.  Also, by
attaching a GPS antenna to the server, an approximate GPS location could be
assigned to nodes within the network.

I think my initial question regarding whether or not the hardware is
currently capable of implementing this system overall is a definitive "Yes,"
so I should be completing my proposal this evening.  I'll post it to the
three mailing lists we've been having this discussion on.  Please feel free
to rip it to shreds, provide constructive criticism, or wish me luck as you
see fit :)
