Answer» GSM/CDMA: CELL and SECTOR with multiple frequency / CDMA single frequency as carrier {users are get identifies by codes} used TDMA and FDMA for Accesing /CDMA uses CDMA method GSM is INTIAL 2G technology with intial voice rate of 9.6kbps/same with 14.4kbps GSM emerges into WCDMA/cdma emerges into cdma 2000 power control in acces method is comparitively not efficient (when compare to CDMA)/ cdma as PLL(phase locked loops for power TRANSMISSION) BETTER CALL hand off and network hand off is not smoother in GSM/ CDMA follows soft handoff and handling call hence more efficient GSM use less bandwidth and more power comparitively / CDMA uses less bandwidth and more power cost wise for opeartor GSM is less costlier , but efficiency wise CDMA is better GSM/CDMA:

GSM/CDMA:

CELL and SECTOR with multiple frequency / CDMA single frequency as carrier {users are get identifies by codes}
used TDMA and FDMA for Accesing /CDMA uses CDMA method
GSM is INTIAL 2G technology with intial voice rate of 9.6kbps/same with 14.4kbps
GSM emerges into WCDMA/cdma emerges into cdma 2000
power control in acces method is comparitively not efficient (when compare to CDMA)/ cdma as PLL(phase locked loops for power TRANSMISSION) BETTER
CALL hand off and network hand off is not smoother in GSM/ CDMA follows soft handoff and handling call hence more efficient
GSM use less bandwidth and more power comparitively / CDMA uses less bandwidth and more power
cost wise for opeartor GSM is less costlier , but efficiency wise CDMA is better

GSM/CDMA:
