Handover optimization

Definition

Handover optimization refers to the process of improving the efficiency and effectiveness of transitioning active connections from one network node to another in wireless and mobile networks. This is crucial for maintaining seamless communication, especially in environments where users are constantly moving. Effective handover optimization minimizes latency and packet loss, ensuring a smooth user experience even as devices switch between different access points or cells.
