Integrated Wireless LAN Capability
The Cisco 890 Series is ideal for enterprise small branch offices and small businesses that need to be connected to
larger enterprise networks. These routers help extend corporate networks to secure remote sites while giving users
access to the same applications found in a corporate office. They provide increased reliability for diversity of wireless
data, voice, and video applications. When users require WLAN access, visibility and control of network security are
even more critical at the remote site. The Cisco 890 Series meets this need with a single device that combines
integrated 802.11a/g/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). The Cisco 890 Series wireless models that include
the integrated access point have full feature parity with the Cisco Aironet
®
1250 Series Access Point and can be
used in 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).
