Low Power Wide Area Networks

In an increasingly connected world, wireless connectivity is more essential than ever. Consumer demands are escalating as wireless extends from PC peripherals and home entertainment applications to the Internet of Things (IoT) and Machine to Machine (M2M) communication.

LoRa™, which stands for Long-Range Wireless, is based on a proprietary technology developed by our partner, Semtech. LoRa utilizes a digital spread spectrum modulation and proprietary protocol in the Sub-GHz RF band to enable long range greater than 10 miles, low power and high network capacity.

SIGFOX uses a UNB (Ultra Narrow Band) based radio technology to connect devices to its global network.  The use of UNB is key to providing a scalable, high-capacity network, with very low energy consumption, while maintaining a simple and easy to rollout star-based cell infrastructure.
