What is wireless client roaming?

Wireless client roaming refers to the capability of wireless devices, such as laptops or smartphones, to move between different access points (APs) within the same wireless network without experiencing interruptions in service. This is essential in environments where users need to remain connected while moving around, such as offices, schools, or public spaces.

When a device roams successfully, it can switch from one AP to another that has a stronger signal or is closer, all while maintaining an active session without noticeable delays. This process is often facilitated by protocols such as 802.11r, which helps minimize disconnection times during the handoff between access points. Effective client roaming enhances the user experience by ensuring that connectivity is maintained as users move throughout a coverage area.

The other options do not accurately depict the concept of wireless client roaming; they refer to different aspects of network connectivity. The ability to switch between network types, the process of reconnecting after a disconnection, and the transition from wired to wireless are all separate phenomena that do not encompass the seamless movement between APs that characterizes wireless client roaming.
