I am working on PoC (Push to Talk over Cellullar), I need to find out the API's involved in this operation. So, for this I am trying to find out what all API's involved in Connecting to GPRS Network(usued by PoC).
One General question here, what all the components involved in connection related operations i.e either to GSM or GPRS.
Any idea how Radio waves are generated inside the mobile and what is the software involved in that to trigger the H/W which is doing this?
Thanks and Regards
