The main pain point for the device is the ability to communicate reliably to the gateway or to the cloud and send the sensor data in a secure way. The reliability of communications can be attributed to the performance of a few critical components: a radio transceiver and communications microcontroller as part of the device. Wireless connectivity technologies utilized by consumer devices do not always satisfy the greater performance demands of industrial and healthcare systems. These systems give a higher priority to safety, accuracy, and time sensitivity, and hence demand a more reliable communication. Cellular systems may come close but they put a penalty on data throughput, battery, and ...
