What does the term 'handoff' refer to in cellular systems?

• A. The process of choosing a call setting
• B. The process of terminating a call
• C. The process of transferring an ongoing call from one cell to another
• D. The process of connecting to Wi-Fi

Answer: (C)

The term 'handoff' in cellular systems specifically refers to the process of transferring an ongoing call from one cell to another. This is a crucial function that ensures a seamless experience for users who are moving through different coverage areas while on a call. As a user moves away from the coverage area of one cell tower, the system automatically transfers the active call to another nearby tower, maintaining the call connection without interruption. This process is essential for maintaining call quality and user satisfaction, especially in situations where users are in motion, such as while driving or walking. Handoffs can be categorized into different types, like hard and soft handoffs, depending on how the transition is managed. Hard handoffs disconnect the communication with the current cell before establishing a connection with the next; in contrast, soft handoffs allow connections with multiple cells simultaneously during the transition. Understanding handoff is vital for comprehending how cellular networks operate and provide uninterrupted service in a dynamic environment. The other options do not relate to the concept of handoff; they address other aspects of call management, such as initiation or termination, and connecting to different types of networks like Wi-Fi, which are distinct from the handoff concept in cellular communications.
