What is a ClientLink 4.0? How is it different from Tx-Beamforming?
Cisco ClientLink 4.0 is a beamforming capability built into Cisco Aironet wireless LAN access points. 
When the access point concentrates signals toward the receiving client, that client is better able to hear 
the AP’s transmission, and so throughput is greater. ClientLink also enhances performance in the 
uplink (client-to-AP) direction, so that the AP can also better hear the client communications. The 
result is improved performance in both directions, and doesn’t require any special capabilities in the 
client device to work.
ClientLink works with all client technologies. It makes sure each client type always operates at the best 
possible rate, as determined by the 802.11 access technology supported, network conditions, and the 
distance of the client from the Wi-Fi AP. ClientLink helps maintain maximum client rates.
Can the USB port be used?
The USB port does not have any software support at this time.
