Integrated Secure Wireless LAN Connectivity
Cisco 1800 Series fixed-configuration routers offer additional models with an integrated wireless access point, providing secure routing and
secure wireless LAN services in one device, helping businesses reduce total cost of ownership with simplified WLAN and WAN deployment and
management capabilities. The optional wireless access point supports IEEE 802.11a/b/g simultaneously to provide high-speed wireless capability
and flexibility with the support of 2.4-GHz and 5-GHz dual-band simultaneous operation, making them ideal choices for public hotspot deployments
®
and wireless office solutions. Wi-Fi Certified client devices including Cisco Aironet , Wi-Fi Certified and Cisco Compatible client devices are fully
supported.
The Cisco 1800 Series wireless routers are Wi-Fi Certified and support Wi-Fi Protected Access (WPA) providing secure mutual authentication and
encryption via Cisco IOS Software features to meet the strict demands of today's businesses. These products also provide support for multiple
wireless VLANs that can be configured to provide additional security, segmentation, and separation of wireless users. When using the routers in
conjunction with the Cisco Service Selection Gateway (SSG) and Subscriber Edge Services Manager (SESM), managed service providers can
incorporate service-based authorization and accounting, and service and subscriber management for customizable, on-demand wireless services such
as public wireless hotspots. Additional features such as survivable local authentication allow users to maintain wireless connectivity to the router in
the event that a remote authentication server goes down. Quality of Service (QoS) via Wi-Fi Multimedia (WMM) is also supported. (See Integrated
Services Routers with Wireless Services Solution Overview for more information)???
