I am working in a CDMA system. Actually GSM is frequency conscious. When Freq. channels ends up then no more user is accommodated. But in CDMA system Unlimited users can be accomodated. The only limitation is noise on reverse channel.
1- Channels in GSM depends on the E-1 availbility, but in CDMA on CHM card, u just add a card and increase ur channels.
2- Call procesing is a long topic.
3- Capacity of CDMA is more than GSM.
4- Good, definitely CDMA. With all other adantages of CDMA, faster DATA rates is a very big advantage.
