To all,
Everyone is talking about Voice over IP, and how it will take over the world. I was wondering how it relates to CDMA.
From my very limited understanding of the subject, I understand that the present telephone infrastructure is based on circuit switching, where a telephone company's switch connects your phone with called party's phone in a physical circuit.
In VoIP, voice is digitized, resulting stream is broken into pockets, and these pockets are handled by pocket switches similar to ones in your LAN, and eventually converted back to voice.
I was wondering where CDMA fits in this equation and how it compares with competing technologies (GSM, TDMA, AMPS) when the conversion to VoIP takes place.
On related subject, I am wondering how CDMA deals with data. So far, I have not seen any application of sending data over CDMA. (I am not sure if text paging offered by some CDMA providers qualifies as data)
