Configuring ClientLink
Configuring ClientLink
Cisco ClientLink (referred to as Beam Forming) is an intelligent beamforming technology that directs
the RF signal to 802.11a/g devices to improve performance by 65%, improve coverage by up to 27%
percent, and reduce coverage holes.
Cisco ClientLink helps extend the useful life of existing 802.11a/g devices in mixed-client networks. It
is beneficial for organizations that move to 802.11n and want to ensure that all clients on the network,
regardless of type, are guaranteed the bandwidth and throughput they need.
Note ClientLink is only available on 1140, 1260, 1500, 1600, 2600, 3500 and 3600 series access points.
Note ClientLink is not supported on the 1040 series access points.
Using the CLI to Configure ClientLink
To enable ClientLink, enter this CLI command in interface configuration mode on 802.11n radio
interfaces:
beamform ofdm
Note Currently the ClientLink configuration option is not available through GUI.
ClientLink is disabled by default. Additional details can be found on cisco.com at the following URL:
