This retarded move of disconnecting 2G while on call thing started with smartphones. The old feature phones that I used to have >10 years ago used to suppored GPRS/Edge along with voice call. But since past few years, smartphones dropped doing this. Don't know the reason why. Maybe I should ask someone at work.

So i went to Univercell in bangalore yesterday asking about the release of HTC One and they are saying that its releasing next month...

 

Is it true ?..Why is the phone being delayed so much.? Don't they want to launch the phone already..

I am not sure but I think my friends downloading is not interrupted while on call :scrachin: I don't use data packs so can't say.

 

@shantz - So, are they promoting 3G by this move?

Actually I asked this at work today and here is what I learnt.

 

So, basically Class A 2G devices (that can support simultaneous voice and data) require an extra antenna so that CS (circuit switched - voice) and PS (packet switched - data) communication can happen simultaneously. There is no perceived benefit of this to OEMs these days while adding costs and complexity to a phone which is already burgeoning with several antennas.

There is a mechanism in GSM called DTM which can support this with a single antenna (i.e. for class B devices) but it requires N/W support and most operators don't deploy it.

That sounds easy :P

As a matter of fact, I PERFECTLY understood. Class A, Class B, Packet, ckt, msg switching. IP, Subnet, TCP/IP etc are all my part of syllabus in computer network :P In fact I was reading it this morning. Sem is coming. So yeah, understanding this kind of statement is a part of my job :P
