'''ARLAN''' is a family of both proprietary non-802.11 and 802.11-compliant wireless networking technologies developed and marketed by [[Company:Aironet Wireless Communications|Aironet Wireless Communications]] in the 1990s prior to Aironet's acquisition by [[Company:Cisco Systems|Cisco Systems]].  Operating in the 900 MHz and 2.4 GHz ISM bands and offering a nominal 2.0 Mbit/s throughput, the non-802.11 DSSS products competed directly with [[Company:NCR Corporation|NCR]]'s [[WaveLAN]] technology.  After acquisition, the ARLAN lineup was renamed to Cisco Aironet; the non-802.11 products were supported briefly then discontinued.
==Hardware==
The ARLAN lineup consisted of several offerings:

===900 MHz DSSS non-802.11===
*Half-length [[Engineering:Industry Standard Architecture|ISA]] card, part number 655-900, RP-TNC connector.  Cisco part number 200-001292.
*[[Engineering:Micro Channel architecture|MCA]] card, part number 670-900, RP-TNC connector
*PC card, part number 690-900, large external antenna dongle
*900 MHz [[Wireless access point|access point]], part number 630-900
*900 MHz [[Network bridge|bridge]], part number 640-900
