Roaming Client Devices If you have more than one wireless device in your wireless LAN, wireless client
devices can roam from one wireless device to another. The roaming functionality
is based on signal quality, not proximity. When signal quality drops from a client,
it roams to another access point.
Wireless LAN users are sometimes concerned when a client device stays
associated to a distant access point instead of roaming to a closer access point.
However, if a client signal to a distant access point remains strong and the signal
quality is high, the client does not roam to a closer access point. Checking
constantly for closer access points can be inefficient, and the extra radio traffic
can slow throughput on the wireless LAN.
By using Cisco Centralized Key Management (CCKM) and a device providing
WDS, client devices can roam from one access point to another so quickly that
there is no perceptible delay in voice or other time-sensitive applications.
