[Discuss-gnuradio] cellular and satellite phones

[Jamie Morken]

Hi,

I am currently working on a handheld device that 
uses a OEM cellular/GPS combo-module with a SIM 
card.

Here is our project website:
http://sourceforge.net/projects/m-pad/

Here is the quad-band cellular/GPS module we are 
using:
"http://www.telit.co.it/modulef.asp?famId=13&famName=GM862-GPS%20Modem";

There is also an FM radio IC on our device as well
as a bluetooth+802.11g combo module:
"http://www.embeddedworks.net/newsite/WLAN/oem_sip_80211g.html";

I would like to add also satellite phone capability 
to this device.  However except for the Thuraya 
network, there don't seem to be any voice+data 
capable small OEM modules for the satellite 
networks, so I am curious if anyone has been working
on a software satellite phone or if the protocol is
publicly available?

Soon I would like to integrate some or all of these 
RF modules into a hybrid software radio, but for now
we are using the OEM modules.

cheers,
Jamie
