Environmental conditions can also be challenging for wireless measurement devices and data transfer. “However,” says Talvitie, “IoTKey® has solved the challenges faced by our mining industry customer. Its range is long enough to cover an area with a radius of about 5 kilometers around an open-pit mine. Now environmental monitoring and gathering the necessary measurement data can be automated at quite low cost.”
The long range capability of IoTKey® is enabled by low-frequency LoRa data transmission. The desired area can be covered by a local LoRa network in which the IoTKey® gateway usually acts as a base station and router. Data transfer in a LoRa network is also encrypted in the same way as in cellular networks.
The measurement data obtained from the IoTKey® gateway is usually delivered directly to the company’s automation system, as is also done in mine site monitoring. In this case, both the data and the entire solution are always in the hands of the company – without any additional costs or parties involved.
