The Cisco 880 Series is ideal for small branch offices and teleworkers who need to be connected to larger
enterprise networks as well as small businesses, for either voice or data applications. These routers help extend
corporate networks to secure remote sites while giving users access to the same applications found in a corporate
office. When users require WLAN access, visibility and control of network security are even more critical at the
remote site. The Cisco 880 Series meets this need with a single device that combines integrated 802.11g/n
capabilities with security features such as Wi-Fi Protected Access (WPA), including authentication with IEEE
802.1X with Cisco Extensible Authentication Protocol (LEAP) and Protected EAP (PEAP) and encryption with
WPA Temporal Key Integrity Protocol (TKIP). (Refer to the wireless solution overview and security data sheet for
more information. The Cisco 880 Series models that include the integrated access point can use either
autonomous or Cisco Unified WLAN modes. In Cisco Unified WLAN mode, as part of an enterprise WLAN
architecture, all WLAN functions are centrally managed through Cisco Wireless LAN Controllers and the Cisco
Wireless Control System (WCS).
Service providers and value-added resellers can take advantage of the Cisco 880 Series to provide a true
business-class broadband service. Business customers are using broadband access to connect to the Internet or
to connect offices together, and they require a platform that incorporates security without sacrificing performance.
Many of these customers are connecting computers in offices through WLANs; having a single device for both
WAN and WLAN access provides a new option for managed services. These customers also require a higher
level of support to keep their networks operational. Services with these customers should be simple to set up,
while allowing a level of remote management and troubleshooting to quickly address support inquiries. The Cisco
880 Series meets the requirements of small offices and managed services providers.
