CISCO STRUCTURED WIRELESS-AWARE NETWORK

The Cisco Aironet 802.11a/b/g Wireless PCI Adapter is a key component of the Cisco Structured Wireless-Aware Network (SWAN). Cisco SWAN
is a framework to integrate and extend wired and wireless networks to deliver the lowest possible total cost of ownership for companies deploying
WLANs. Cisco SWAN extends "wireless awareness" into important elements of the network infrastructure, providing the same level of security,
scalability, reliability, ease of deployment, and management for wireless LANs that organizations have come to expect from their wired LANs.
Wireless domain services (WDS) is introduced with the Cisco Structured Wireless-Aware Network. WDS is a collection of Cisco IOS Software
features that expand WLAN client mobility, simplify WLAN deployment and management and enhance WLAN security. These services—supported
®
on access points, client devices, and the Cisco Catalyst 6500 Series Wireless LAN Services Module (WLSM) today and other Cisco LAN switches
and routers in 2005—include radio management aggregation, fast secure roaming, client tracking, and WAN link remote site survivability. WDS
radio management aggregation supports radio frequency (RF) managed services such as rogue access point detection for WLAN Intrusion Detection
System (IDS), interference detection, assisted site surveys and self-healing wireless LANs. For more information on Cisco SWAN, visit:

Fast secure roaming is supported by Cisco and Cisco Compatible client devices in conjunction with Cisco Aironet, Cisco IOS Software-based access
points. With fast secure roaming, authenticated client devices can roam securely from one access point to another, within or across subnets, 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 (Figure 3).
