The Cisco 870 Series is ideal for small remote offices and teleworkers that need to be connected to larger enterprise networks. When extending
corporate networks to numerous remote sites, network resources must remain secure while giving users access to the same applications found in a
corporate office. This applies to both data and voice applications, where IP phones can be used to extend a corporate voice extension to the remote
office. When users require WLAN access, visibility and control of network security is even more critical at the remote site. The Cisco 870 Series
meets this need with a single device that combines integrated 802.11b/g 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). (See Wireless Solution overview and Security Data Sheet for more information).
