Latest Atheros WiFi Chip Integrates Processor, MAC, Baseband, and Radio functions

Atheros Communications introduced its most integrated single-chip wireless LAN for access point and router products to date. The Atheros AR5007AP-G features a complete 802.11b/g wireless access point system on a chip, combining the wireless network processor, media access controller (MAC), baseband, and all radio functions up to the antenna. The level of integration significantly reduces the cost of implementing 802.11g Wi-Fi in access point products for homes and small businesses.

Atheros said the AR5007AP-G offers a total component reduction of 40 percent versus the Atheros' AR5006AP-G access point solution. Some of the key WLAN components that have been integrated onto Atheros' newest single-chip include an on-chip power amplifier, low noise amplifiers (LNA), antenna switch and transmit/receive filtering. Additionally, the Atheros AR5007AP-G chip requires 100-150 fewer external components than competing solutions. The high level of integration enables the use of a lower cost 2-layer printed circuit board (PCB) and eliminates the need for any external RF shielding -- further reducing the AP bill of materials.

The Atheros AR5007AP-G offers support for IEEE 802.11i security and 802.11e QoS specifications. Additionally, the solution supports Atheros XR (eXtended Range) and JumpStart for Wireless technologies.

Atheros is currently in volume production with the AR5007AP-G with a list price of $12.50 in 10,000-unit quantities.

802.11g devices represent 80 percent of the current WLAN market based on IDC's latest unit forecast, and are expected to account for over two-thirds of the market next year.
