Cisco Cisco Aironet 2600i Access Point

Wireless Domain Services (WDS). An access point providing WDS on your 
wireless LAN maintains a cache of credentials for CCKM-capable client devices 
on your wireless LAN. When a CCKM-capable client roams from one access 
point to another, the WDS access point forwards the client’s credentials to the 
new access point with the multicast key. Only two packets pass between the client 
and the new access point, greatly shortening the reassociation time. 

Wired Equivalent Privacy. An optional security mechanism defined within the 
802.11 standard designed to make the link integrity of wireless devices equal to 
that of a cable.

Wireless LAN Solutions Engine. The WLSE is a specialized appliance for 
managing Cisco Aironet wireless LAN infrastructures. It centrally identifies and 
configures access points in customer-defined groups and reports on throughput 
and client associations. WLSE's centralized management capabilities are further 
enhanced with an integrated template-based configuration tool for added 
configuration ease and improved productivity. 

Wireless Network Manager.

A computing device with an installed client adapter.

Wi-Fi Protected Access (WPA) is a standards-based, interoperable security 
enhancement that strongly increases the level of data protection and access 
control for existing and future wireless LAN systems. It is derived from and will 
be forward-compatible with the upcoming IEEE 802.11i standard. WPA 
leverages TKIP (Temporal Key Integrity Protocol) for data protection and 
802.1X for authenticated key management.
