Enterprise-Class Performance
Cisco’s innovative radio and antenna design delivers industry-leading 802.11a enterprise
performance. It provides for maximum capacity and scalability across the enterprise through
eight non-overlapping channels in the UNII-1 and UNII-2 bands. The integrated 5 dBi gain patch
antenna optimizes range. The –68 dBm receive sensitivity at 54 Mbps provides high-data-rate
range performance. Advanced signal processing in the Cisco Aironet 5 GHz Wireless LAN Client
Adapter helps manage the multipath propagation often found in office environments and intelligent
filtering addresses ambient noise and interference that can decrease network performance.
Various transmit power settings on the Cisco Aironet client adapter enable you to select range
capabilities.

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
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.
