I have always considered GSM/GPRS as best for calls but when comparing data transfers CDMA is far far bettr than GPRS. it gives upto 144kbps speeds as compared to gprs's 40-50kbps even edge's 60-80kbps. any one techie enuff to point the reason?

I don't have GPRS but I would like to have one . I sure a CDMA and it is of but I would not alway use it .

Are you sure about it? It could be the difference between KBps and kbps. They are showing the speed differently, I believe.

Hey, I keep running into you wherever I go.
Anyways, The way I understand it, CDMA was designed keeping data transfers a priority. That is the reason that sms packs are cheaper in cdma.

You seem to have the throughput's mixed up.
GPRS has max speed of 48 kbps
EDGE has max speed of 384 kbps
CDMA has max speed of 144 kbps.
(Don't ask me why there are so many recurring 4's.)

All this is indicative and theoretical max. These speeds are almost never reached. Also keep in mind that these are kilo[B]bits[/B] not kilo[B]bytes[/B]

So actual speeds are GPRS = 6 KBps, EDGE = 48 KBps, CDMA = 18 KBps.

I am not sure how CDMA works, but GPRS and EDGE work upon a Timeslot basis. Basically they get a certain slot of time and have to send data only in that slot. EDGE has more slots allowed than GPRS and also has more transfer rate, so it is faster than GPRS.

Okay, I wont ask you why you have so many recurring 4's. And I though CDMA workked on TDMA not gsm?

Although this thread is full of information but I think we can't compare GPRS and CDMA(I might be wrong). I think CDMA facilitate customers through local looping and GPRS is a universal thing so CDMA always work faster than GPRS.

cdma is better in voice clarity and data transfer but due to wide companies offer gsm its gsm which is favourable and nobody uses a mobile for for regular net connection
