[aprssig] RE: APRS for One-Laptop-Per-Child

[John Habbinga]

If the OLPC laptops have Wi-fi, then perhaps a database of locations of 
wireless access points could be logged.  Instead of using GPS, the OLPCs 
would triangulate their position based on the known locations of the 
wireless access points.

This would be really helpful when used indoors where GPS coverage is 
lacking.  A student could locate a teacher or another student that is using 
an OLPC in a large school building.
