Hello,
GSM and CDMA have following differences:-
GSM stands for global system for mobile communication.
CDMA for code division multiple accesses.
GSM is a form of multiplexing, which divides the available
bandwidth among the different channels. Most of the times
the multiplexing used is either TDM (Time division
multiplexing) or FDM (Frequency division multiplexing).
CDMA is a type of multiple access scheme( which means
allotting the given bandwidth to multiple users) and makes
use of spread spectrum technique which is essentially
increasing the size of spectrum.
In CDMA each user is provided a unique code and all the
conversation between 2 users are coded. This provides a
greater level of security to CDMA users than the GSM ones.
