How does handoff takes place in a mobile communications system?

Question

Accepted Answer

Handoff is the process of transferring an ongoing call or data session from one cell to another in a mobile communications system.

Handoff occurs when a mobile device moves out of the range of one cell and into the range of another.
The system monitors the signal strength of the mobile device and initiates handoff when the signal strength drops below a certain threshold.
Handoff can be hard or soft, depending on whether the connection is broken during the transfer or not.
Examples of handoff include moving from a Wi-Fi network to a cellular network, or from one cell tower to another while driving.
Handoff is important for maintaining a seamless user experience and preventing dropped calls or interrupted data sessions.
