Low-Power Wide-Area Networks (LPWANs) are becoming one of the main building blocks for the Industrial IoT (IIoT) ecosystem, being an alternative to 2G/3G/4G cellular networks where long-range communication at very low speed is needed by battery powered sensors spread around the factory. Among the most promising approaches, SIGFOX stands out as an ultra-narrow band technology that allows similar signal...
