Atheros Communications' wireless software for its Radio-on-Chip for Mobile (ROCm) has undergone and passed rigorous, extensive Microsoft tests for use with the latter's just introduced Windows CE 6.0. Both companies have received Wi-Fi Alliance certification for 802.11 devices.
Atheros' ROCm family products that support Windows Embedded CE 6.0 include the AR6001GL single-chip 802.11b/g and AR6001XL single-chip 802.11a/b/g WLAN solutions.
Additionally, the ROCm family provides full-speed, hardware-based security compliant with the WPA, WPA2 and 802.11i standards, and fast-roaming capabilities optimized with Windows Embedded CE 6.0.
The fast-roaming feature enables dual-mode handsets to seamlessly switch between wireless access points when a user moves throughout a building or enterprise campus. The result is clear, undisrupted, latency-sensitive applications such as VoIP calls and media downloads.
Typically, said Jane Gilson, director of the Windows Mobile and Embedded Devices Group at Microsoft Corp., handset and Consumer Electronics manufacturers invest a considerable amount of development and test time integrating wireless capability into the Windows Embedded CE platform for each unique device design. Adding Atheros' WLAN subsystem into the Windows Embedded CE 6.0 platform, she said, provides manufacturers with pre-integrated, tested wireless functionality without the extensive development and time expense.
Sam Endy, vice president and general manager, mobile wireless for Atheros, said the AR6001GL and AR6001XL chipsets are designed with a network setup based on the forthcoming Wi-Fi Alliance configuration standard and a rich feature set including prioritized and polled Quality of Service (QoS) extensions (802.11e and WMM).
Additionally, he said, high-throughput transmissions enabled with Atheros WLAN minimize transmit/receive times to further extend sleep mode. A self-contained driver on the chips' embedded processor takes routine network maintenance tasks off the host processor's load to achieve incremental power savings.
