Atheros Has Single Chip 802.11g

By Glenn Fleishman

Atheros integrates 802.11g into a single CMOS chip, shipping 2nd quarter: The company is already sampling its AR5005G chipset, which comprises a single chip containing the Media Access Controller (the part that handles digital network interaction), the baseband processor (the part that handles converting analog to digital and the opposite), and the 2.4 GHz radio.

The company claims the same performance characteristics as their multi-chip 802.11g solution, including improvements in range. They also say that their WPA and 802.11i encryption support can be used without a reduction in throughput. The chip also features adaptive power use that selectively powers parts of the chip as needed.

This 802.11g design is another step in “Wi-Fi everywhere,” in which all business and consumer electronics include Wi-Fi as a default fact, not an add-on at extra cost or only found in special models. We’ll be talking to the company later today; watch for another report in the afternoon.
