Certified Wireless Network Administrator (CWNA) 2025 – 400 Free Practice Questions to Pass the Exam

Roaming in a wireless network primarily serves the function of allowing clients to maintain connectivity while moving between access points. When a user moves from one area covered by one access point to another area covered by a different access point, roaming ensures a seamless transition. This process is crucial in environments like offices, campuses, or public spaces where users expect uninterrupted service as they move around.

As a device moves, its connection to the closest access point might weaken, and roaming facilitates the transfer of the connection to a stronger signal from a nearby access point. This function enhances user experience by ensuring that applications remain responsive and users stay connected without noticeable interruptions.

Other options describe different functionalities. For instance, data encryption focuses on securing communications, whereas bandwidth allocation specifically pertains to managing the amount of data each user can transmit over the network. Remote access refers to enabling users to connect to the network from external locations, which is distinct from roaming.
