What is Handover and Handoff?
In the field of communication, “handover” and “handoff” are two terms that are often used interchangeably but actually have slightly different meanings. Understanding these terms is essential for effective communication, especially in the context of mobile networks and wireless technology.
Handover
Handover refers to the process of transferring an ongoing communication session from one communication channel to another. It is a crucial procedure in wireless networks when a mobile device or user moves from one cell or base station to another. Handover ensures the continuity and smooth transition of the communication session, allowing the user to maintain a reliable connection.
To visualize this concept, imagine a scenario where you are talking on your mobile phone while walking down the street. As you move away from one cell tower’s range, the network system initiates a handover to hand off the call to a neighboring cell tower. This seamless transition allows you to continue your conversation without any interruption.
Handover can also happen in scenarios such as switching between different wireless access points in a Wi-Fi network or transferring a call from one landline connection to another.
Handoff
Handoff, on the other hand, refers to the action of transferring a communication session, specifically in the context of wireless communication, from one channel or frequency to another. It is a technical process that ensures the continuous transmission of data or voice signals as a user moves within a network.
In the case of mobile networks, handoff takes place when a mobile device, such as a cell phone, moves from the coverage area of one cell to another. During a handoff, the network system seamlessly switches the device’s connection to a different frequency or channel, ensuring uninterrupted service.
Similar to handover, handoff also happens in other wireless communication systems like Wi-Fi networks, where a device can switch between different access points as needed.
Key Difference
The main difference between handover and handoff lies in their perspectives. Handover focuses on the user’s perspective, emphasizing the transfer of a communication session. It ensures an uninterrupted connection as the user moves between different network elements.
Handoff, on the other hand, emphasizes the technical process of moving the communication session from one channel to another, ensuring seamless transmission of data or voice signals.
Both handover and handoff are essential mechanisms in maintaining uninterrupted communication in various wireless networks. They play significant roles in ensuring a seamless user experience, especially when it comes to mobile communication.
By understanding the difference between handover and handoff, we can appreciate the complexity and importance of these concepts in modern communication systems. Their seamless execution allows us to stay connected and engaged, regardless of our location or movement within a network.
