GSM is a Global Syatem For Mobile Communication.

GSM Operates 3 bands, 1) GSM 900 2) GSM 1800 and 3) GSM
1900.

GSM 900 & GSM 1800 are used in india, But, GSM 1900 used in
USA.

GSM and CDMA techniques can be explained with an example,

suppose there are 10 persons in a room and they want to
communicate with each other .How can they communicate?
First method:One persons speaks at one time that means we
have provided a definite time interval to that person.-GSM
Second method :all the peers speak at a time in a different
language which we call as CDMA

CDMA stands for Code Division Multiple Access and GSM
stands for Global system for Mobile Communication.
In CDMA phones the software is integral with the phone
instrument and in the case of GSM phones it is through the
SIM Card.

CDMA phone instruments are dedicated to the service
provider. GSM phone instruments are portable across service
providers through SIM cards.
