Aironet ARLAN

ARLAN is a family of both proprietary non-802.11 and 802.11-compliant wireless networking technologies developed and marketed by Aironet Wireless Communications in the 1990s prior to Aironet's acquisition by 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 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

2.4 GHz DSSS non-802.11

2.4 GHz FHSS early 802.11 draft D5 compliant
