Lenovo Group Ltd (formerly Legend Computer), a PC vendor in China, has integrated Atheros Communications' single-chip 802.11g solution into new wireless-enabled laptops that will be sold in China and other markets.

Launched on January 14, 2005, several models of Lenovo's Y200 laptops feature built-in wireless capability based on the Atheros AR5005G, a complete single-chip IEEE 802.11g WLAN solution. The chip integrates an entire 802.11g solution -- media access controller (MAC), baseband processor, high-performance 2.4GHz radio, and many discrete components -- in an integrated low-cost digital CMOS (complementary metal-oxide semiconductor) design.

According to Atheros, the AR5005G 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 power-saving technique allows the chip to consume up to 98 percent less power than multi-chip WLAN solutions on the market.

The AR5005G includes hardware support for the latest WLAN security standards, including Wi-Fi Protected Access and 802.11i Enhanced Security using Advanced Encryption Standard (AES), so there is no reduction in performance, added Atheros.
