A new wireless Ethernet card being developed by Atheros Communications is capable of sending and receiving data at up to 72 Mbps – seven times faster than the 11 Mbps available with current 802.11a technology like Apple’s Airport. The Atheros AR5000 PC card utilizes the 5 GHz band as opposed to the overcrowded 2.5 GHz band.

By reengineering and optimizing conventional radio architecture, Atheros has developed a breakthrough in next-generation wireless local area network (LAN) semiconductor technology. The company has made possible the world’s first complete “Radio-on-a-Chip”(RoC) at 5-GHz using standard-process CMOS.

Additionally, as a 5-GHz solution, the Atheros AR5000 chipset is free of interference from microwave ovens, 2.4-GHz cordless phones, and other technologies such as Bluetooth and HomeRF which compete for the 2.4-GHz Industrial, Scientific and Medical (ISM) frequency band.

The company plans to produce the card this summer. The only catch, it will only operate at a throttled-down 54 Mbps because of limitations in the current IEEE standards.
