Qualcomm Atheros Intros 802.11n for Low-Energy M2M Sensors

Qualcomm Atheros introduced a new 802.11n single-stream Wi-Fi system-in-package with integrated networking stack and aimed at machine-to-machine (M2M) communications in the smart home, building and appliances channels.

The AR4100P is an enhanced version of the FCC-certified AR4100 that includes an integrated IPv4/IPv6 TCP/IP stack. It is the latest product within the Qualcomm Atheros Internet of Everything portfolio. The new device is featured in Qualcomm Atheros' SP137 development kit, which is a reference design for low-power IP sensors. The development kit integrates Energy Micro's EFM32 Gecko low-energy Cortex-M3 microcontroller running the Micrium uC/OS-III operating system. With a well of additional onboard sensors, the energy friendly Wi-Fi kit supports deep sleep modes of only 2uA, enabling operation off just AA batteries.
