GSM means Global Standard for Mobile Communication which
uses TDMA + FDMA as its technique whereas CDMA is Code
Division Multiple Access. CDMA generates Random sequence
code for each user to access the spectrum. Advantages of
CDMA are Less interference, highly secured communication and
effective utilization of available frequency.
