Table 1. Product Features and Benefits

Product Features Benefit

Industry-Leading Security

WPA Certified Cisco Wireless Security Suite includes IEEE 802.1X mutual authentication with Cisco

LEAP, EAP-FAST, PEAP-GTC, PEAP-MSCHAP V2, EAP-TLS and EAP-SIM, Cisco TKIP, and WPA

TKIP support.

Multiple Transmit Power Settings

(20 mW/(13 dBm), 10 mW/(10 dBm),

and 5 mW (7 dBm)

Provides flexibility to limit RF coverage. Multiple transmit power settings are especially useful when

coupled with one of the broad antenna offerings to direct or limit RF coverage.

Hardware-Accelerated

WEP Encryption

Minimum degradation when encryption is enabled, resulting in maximum throughput.

Quiet Mode

Forces the client adapter to become quiet (to passively scan or listen) when its associated access point is

turned off. The client generates radio frequency energy only in direct response to an access point

transmission. It applies to individual cards rather than profiles and can be set differently for different

cards remaining in effect across Aironet Client Utility sessions and computer reboots.
