Soft handover, often used in CDMA (Code Division Multiple Access) networks like 3G, is a process where a mobile device maintains simultaneous connections to two or more cell sites (or sectors of the same site) during a transition from one cell to another. This contrasts with “hard handovers,” where the connection to the current cell is broken before or as the connection to the new cell is established.

Benefits of soft handover:

  1. Seamless Transition: Since the device is connected to both the old and new cell simultaneously, the transition is smooth, reducing the chances of dropped calls.
  2. Improved Signal Quality: By being connected to multiple cells, the device can combine signals to improve overall reception.
  3. Reduced Interference: The simultaneous connection allows for better coordination between cells, reducing the potential for interference.

Overall, soft handovers are designed to provide a better user experience by ensuring continuity of connection and improved call quality.
