Aironet ARLAN
From Wikipedia, the free encyclopedia
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 1990's 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.
