Public WLAN Hotspot Service—Integrated 802.11 Access Points, AZR, PoE, and
SSG Support
The Cisco integrated services routers provide a complete solution for public WLAN hotspots (or
access zones) in a single device.
Integrated 802.11b/g and 802.11a/b/g WLAN Connectivity
As described earlier, Cisco integrated service routers offer an integrated 802.11b/g or 802.11a/b/g
access-point option for Wi-Fi hotspot services.
AZR
AZR capability helps ensure that the hotspot network is secured for authorized public access. An
AZR with an integrated 802.11 WLAN eases the deployment and configuration necessary to
provide an accessible and secure public Wi-Fi hotspot. Acting as an AZR, the integrated services
routers can be used with an integrated access point or can be used to extend services to discrete
access points connected to 10/100BASE-T switch ports on the integrated services router. In
addition, the routers can provide Inline PoE to the external access points.
The integrated services routers support the full suite of AZR features, including:
Secure Address Resolution Protocol (ARP)—IP Spoofing
Called station ID (CSID) format
Authorized ARP—IP Spoofing and session termination
Automatically operational static address support
