Atheros announces a complete single-chip IEEE 802.11g WLAN solution, the AR5005G. The chip integrates an 802.11g solution -- Media Access Controller (MAC), baseband processor, and a 2.4 GHz radio, in an integrated digital CMOS design. Atheros has integrated many discrete components of previous 802.11g solutions into the new design and the result is a 35% part count reduction from products based on two-chip solutions. The product uses a multi-phase approach to signal processing, which extends the battery life of mobile devices by controlling the power of different sections of the wireless device according to the level of system and network activity. The AR5005G supports in hardware, without performance reduction, the latest WLAN security standards, including WPA and WPA2 and 802.11i Enhanced Security using AES.
