In GSM, FDMA( Frequency Division Multiple Access) and TDMA (Time Division Multiple Access) are togetherly used.

Answer / siddhu

cdma acronym is "code division multiple access" .It works
by assigning a particular code to subscriber while making a
call so that it has flexible bandwidth to use...

where as gsm acronym is global system for mobile
communication it does us different frequencies and
bandwidth . its quality is far better compared to cdma...

Answer / abhinav palhade

in cdma, fdma & tdma together are used.in gsm,there are no
such fundas.there are different freq bands in cdma and the
n/w user is shifted or assigned over another band after
some amount of time.but in gsm, many users are bounded tyo
ese same freq band.thats why we get clear n/w in cdma.
