4-port 10/100 FE LAN Switch
This switch provides four ports for connecting to 10/100BASE-T FE LANs, access points, or IP phones. A factory-installed upgrade is available that gives Power over Ethernet (PoE) on two of the ports to provide power to access points or phones.
802.11b/g/n Wireless LAN
The Cisco 880W series ISRs have an integrated 802.11b/g/n radio module for wireless LAN connectivity. With this module, the router can act as an access point in the local infrastructure.
For more information on supported WLAN radio modules, see Table 1-1.
Battery-backed-up Real-Time Clock
A battery-backed-up real-time clock (RTC) provides the date and time when the system is powered on. The RTC is used to verify the validity of the Certification Authority stored on the router.
Cisco CleanAir Technology
The Cisco CleanAir technology is a system-wide feature of the Cisco Unified Wireless Network that improves air quality by detecting RF interference that other systems cannot recognize, identifying the source, locating it on a map, and then making automatic adjustments to optimize wireless coverage.
Cisco access points with the CleanAir technology provide the highest-performance 802.11n connectivity for mission-critical mobility. By intelligently avoiding interference, the access points offer performance protection for 802.11n networks to help ensure reliable application delivery.
