let's see what do we mean by a handoff procedure consider a situation where we are traveling from place a to place B via a car sometimes it happens that for a short period of 2 or 3 seconds the signal strength on mobiles becomes very low and again it increases and reaches its normal level have you ever thought why this happens the answer to this question is the handoff procedure when someone user X travels in area a he receives the signal from base station that is antenna a has a stronghold on out devices signal but as he moves away from antenna a the signal strength gradually decreases at a boundary of cell a the holder of antenna a on the device is minimum at the same time when the device is about to enter into cell B base station B starts to take hold on the device thus at the border of cell a and cell B both the antennas have equal amount of hold on the device of user X as user X crosses the border and enters into Selby area B strength of base station a very rapidly decreases and strength of base station B rapidly increases in short the device receives the signal network from base station B but during this procedure the call is still on hence base station a handovers this call to base station B without any effect on a call this procedure is known as the handoff procedure this process happens so rapidly that the user never notices it you
