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.
