Wireless Services
Overview

Wireless domain services (WDS) is introduced with the Cisco Structured Wireless-Aware Network. WDS is a collection of Cisco IOS Software features that enhance WLAN client mobility and simplify WLAN deployment and management. WDS includes aggregation of Air/RF measurements .

All access points in a subnet detect and securely register, through IEEE 802.1x, with the WDS. The WDS aggregates client and access points RF measurements for RF managed services such as rogue AP detection, interference detection (demonstrated by the 2.4 GHz phone in Figure ), and assisted site surveys. The currently supported WDS feature set includes fast secure roaming and IEEE 802.1x local authentication. Additional WDS feature sets are planned for future software releases.

Fast secure roaming allows authenticated client devices to roam securely from one AP to another without any perceptible delay during reassociation . Fast secure roaming supports latency-sensitive applications such as wireless voice over IP (VoIP), enterprise resource planning (ERP), or Citrix-based solutions, without dropping connections during roaming. WDS provides fast, secure handoff services to access points for <150ms roaming within a subnet. Cisco fast secure roaming requires Cisco or Cisco Compatible client devices that support the Cisco Centralized Key Management (CCKM) protocol.
