GSM/CDMA
1. CELL and Sector with multiple frequency / CDMA single
frequency as carrier {users are get identifies by codes}
2. used TDMA and FDMA for Accesing /CDMA uses CDMA method
3. GSM is intial 2G technology with intial voice rate of
9.6kbps/same with 14.4kbps
4.GSM emerges into WCDMA/cdma emerges into cdma 2000
5. power control in acces method is comparitively not
efficient (when compare to CDMA)/ cdma as PLL(phase locked
loops for power transmission) better
6.call hand off and network hand off is not smoother in
GSM/ CDMA follows soft handoff and handling call hence more
efficient
7. GSM use less bandwidth and more power comparitively /
CDMA uses less bandwidth and more power

8.cost wise for opeartor GSM is less costlier , but
efficiency wise CDMA is better
