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.
The ARLAN lineup consisted of several offerings:
900 MHz DSSS non-802.11
2.4 GHz DSSS non-802.11
- Half-length ISA card, part number 655-2400 (later renamed to IC 2200), RP-TNC connector
- MCA card, part number 670-2400, RP-TNC connector
- PC card, part number 690-2400 (later renamed to PC 2200), large external antenna dongle
- 2.4 GHz access point, part number 630-2400
- 2.4 GHz bridge, part number 640-2400
- 2.4 GHz high-speed bridge, part number BR2040-EE
2.4 GHz FHSS early 802.11 draft D5 compliant
- 2.4 GHz PC card, part number PC3000
- 2.4 GHz PC card, part number LM3000
- 2.4 GHz access point, part number AP3000
