>GSM means globel system mobiles ,in this case the antenna
provide 30 to 60 channels at a time i.e;30 or 60 gsm users
are connect at a time..
> the communication process will be
sorce-transduser-transmitter-channel-sattelite-channel-transducer-reciever,
it has much more complex.
>CDMA means code division multiple access i.e;it transmits
the given data in code(i.e;digital(0&1)).
>there consists of fixed no.of channels that is very
less,this is the main draw back of the cdma over gsmm
>The communication process takes place source
source-channel-sattelite-channel-reciever.
>it is nothing but a sattelite phone ,bcoz nobody can track
this mobile.
