The product comprises a M.2 802.11ah communication module and the latest Raspberry Pi 3, claiming to be the the first to incorporate the HaLow module and Raspberry Pi 3. The module is equipped with the 802.11ah Wi-Fi SoC (NRC7292) from NEWRACOM.

The HaLow module, now featuring Cortex-MO and M3 dual processors, is designed for low-bandwidth, long-range, low-power and massive IoT applications that support 802.11ah communication standards. The data throughput reaches out to 1-Mbps within 1km coverage and on a 1-MHz channel bandwidth. In parallel, the newly released Raspberry Pi 3 is optimized for devices running on the Linux operating system and supports the integration of most functions on IoT devices.

Optimized for IoT devices, the NRC7292 from NEWRACOM is compliant with the IEEE 802.11ah standard. Operating in the sub 1-GHz license-exempt band, it offers a much greater range over 2.4 GHz and 5 GHz technologies. Further, 1-/2-/4-MHz channel widths with optional short guard interval (SGI) yield 150 Kbps to 15 Mbps PHY throughput, which can support low-rate sensor to high-rate surveillance camera applications. The protocol’s power-saving mechanisms like a longer sleep time greatly reduces power consumption and hence increase battery life.

The self-contained IEEE 802.11ah Wi-Fi networking capabilities with fully integrated radio transceiver of the NRC7292 offers the ideal way to add Wi-Fi connectivity to IoT products. It minimizes the PCB size, requires minimal external circuitries, and enables fast time-to-market.

In response to growing market needs for IoT and advanced application, the launch of the Raspberry Pi 3 based HaLow Wi-Fi system system enables customers to accelerate designs for a wide array of IoT applications such as smart home/office/industry/city, healthcare, smart grid and security.

“HaLow promises delivery of up to 1-Mbits/s over a distance of one kilometer and support for thousands of nodes on an access point,” said James Horng, general manager of Fortune Tech System.
