Qualcomm Atheros announces the launch of Wi-Fi system-in-package for intelligent home and building markets

Qualcomm Atheros Inc., the networking and connectivity subsidiary of Qualcomm Incorporated, announced the launch of the AR4100P, a highly integrated 802.11n single-stream Wi-Fi system-in-package with integrated networking stack. The AR4100P is an enhanced version of the FCC-certified AR4100 that includes an integrated IPv4/IPv6 TCP/IP stack. Aimed at customers implementing machine-to-machine (M2M) communications in the smart home, building and appliances channels, the AR4100P provides system designers a more highly integrated solution, thereby lowering system costs and simplifying system design. The AR4100P is featured in Qualcomm Atheros’s 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 µC/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.
