Welcome to the Aironet 4000 Series Wireless LAN Adapter

Link Test

The link test tool is used to determine RF coverage. The test results help the installer eliminate low RF signal level area that can result in loss of connection.

Radio Antenna

The Snap-On Diversity antenna comes standard with the PC Card and provides omni-directional coverage.

A benefit of the diversity antenna system is improved cover- age. At the edges of the RF coverage or fringe areas, there are very often multiple signals reaching the receiver, all from the same transmitter. These signals travel in different paths (multipath) and are caused by reflection and shadows of the RF signals. When the signals combine, the receiver may have trouble decoding the data. The Aironet radio’s ability to switch and sample between these antennas allows it to select the optimum antenna for receiving the packet.

Optional antennas are offered for the PC Card. Consult the Aironet Antenna Guide document number 710-003725 for more information.

Security Features

The Aironet 4000 Series Wireless LAN Adapter employs Direct Sequence Spread Spectrum Technology, previously developed for military “anti-jamming” and “low probability of intercept” radio systems.

The Aironet Access Point must be set to the same Service Set Identifier (SSID) as all other Aironet devices on the wireless infrastructure. Units with a different SSID will not be able to directly communicate with each other.
