Not that silly, though the context is wrong.

The calls would be less reliable with lower quality of service, the problems increasing with the number of simultaneous callers, plus their phones would eat up power like crazy. > I thought that the absence of this feature was a limitation > imposed on the user from the phone builders.

With GTA02, you should be able to do Wifi mesh networking and route VOIP calls through that, if you like. Just that, well, see above. (With GTA01, all you have is Bluetooth, and while it's suitable for a lot of stuff, let's just not.) What you can't do is use the GSM frequencies for this kind of thing, first because you don't have access to the GSM chip firmware, and second because transmitting on the GSM spectrum without timeslot allocations from the cell tower will cause you to interfere with people's calls, some of them emergency ones. Plus the illegality of it all. -- Mikko J Rauhala <[EMAIL PROTECTED]> University of Helsinki _______________________________________________ OpenMoko community mailing list [email protected] http://lists.openmoko.org/mailman/listinfo/community
