| Hi,
I am looking for GSM and GPRS class system. i have some information
such as
The GPRS mobile phones can be classified into the following three
classes in terms of the possibility of simultaneous calls (via GSM) and
data transmission (via GPRS)...
Class A - Simultaneous calls (via GSM) and data transmission (via GPRS)
Class B - Automatic switching between the GSM and the GPRS mode is
possible
according to telephone settings.
Class C - Hand operated switching between the GSM and the GPRS mode
Data Transmission Speeds
The supported data transmission speed per channel is 13.4Kbits.
Depending on the type of phone, the following data transmission speeds
are theoretically possible...
Type 2+1: Receive 26.8Kbits and send 13.4Kbits.
Type 3+1: Receive 40.2Kbits and send 13.4Kbits.
Type 4+1: Receive 53.6Kbits and send 13.4Kbits.
can some one give me more details or links.
Aloha,
Sumeet

And this has what to do with alt.cellular.verizon? Verizon is CDMA.
There's nothing GSM about it. Why didn't you go to the group
alt.cellular.gsm ?
