WHY DO WE NEED FREQUECY HOPPING ?

Frequency hopping serves three major purpose in GSM

 
1) FREQUECY RESUSE AND TO AVOID CO-CHANNEL INTERFERENCE
2) INCREASES THE  CHANNEL CAPACITY OF LIMITED GSM CHANNELS
3) DECREASES MULTIPATH INTERFERENCE OF RADIO SIGNAL.
 
 
"  Frequency Hopping  rule is simple,  that our conversation must remain on the same physical channel and time slot for the entire time we are on a particular site. If the network were able to move us from slot to slot, and from frequency to frequency, then we could randomize the effects of interference "
