unicast packet

The power level of radio transmission.

Unlicensed National Information Infrastructure—regulations for UNII devices operating in the 5.15 to 5.35 GHz and 5.725 to 5.825 GHz frequency bands.

Regulations for UNII devices operating in the 5.15 to 5.25 GHz frequency band.

Regulations for UNII devices operating in the 5.25 to 5.35 GHz frequency band.

Regulations for UNII devices operating in the 5.725 to 5.825 GHz frequency band.

A single data message (packet) sent to a specific IP address.

W

WDS

Wireless Domain Services. 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.

WEP

WLSE

Wired Equivalent Privacy. An optional security mechanism defined within the

802.11standard 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.

WNM

Wireless Network Manager.

workstation

A computing device with an installed client adapter.

WPA

Wi-Fi Protected Access 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.
