Hello everyone,<br><br>I'm new to openmoko, with a clear project in mind.<br>I have heard of these new mobile phones that are able to switch between GSM and Wifi on-the-fly.<br><br>Why is it interesting? This handover thing is currently developed by some mobile operators as a "very useful service" to set-top-boxes owners. An implementation in openMoko could be interesting. Moreover, currently most wifi phones only use skype, but using GSM allows a network switch without breaking the communication.
<br><br>Of course it won't exist until we have wifi embedded, but it's always possible to prepare!<br>
<br>
We could imagine a multi-network application for openmoko dialer:<br>-direct with GSM<br>-GSM trough Wifi (with automatic handover to plain GSM when wifi becomes unavailable, etc... )<br>-SIP<br>-Skype<br><br>According to GSM specs, GSM data packets can be tunneled over an IPSec tunnel to dedicated access routers.
<br clear="all"><br>Do you think we have enough information about the GSM modem embedded in this phone to allow this service to be implemented?<br>I have followed the parallel thread on this list about modem documentation, but it doesn't help me, cause I don't know if accessing GSM packets can be
<br>achieved through AT commands interface or not.<br><br>As this modem has a separate audio path, I guess it will be difficult, but it would be great if someone of you could confirm or explain all of this...<br><br>Thank you very much.
