The LoRa (for “Long Range”) network can be used to generate private networks with secure and encrypted communication. This means that the data is controlled, it remains with the company (locally), and it does not depend on a wireless provider. The range between the transmitter and the receiver is 500 metres (the record being more than 40 kilometres), which enables the entire industrial site to be covered with just a few antennas and provides redundancy in the event of faults. The installation is less costly and simpler to implement than a wired solution. The devices can operate off batteries, with a battery life of around five years.
Another advantage is that this solution can retrieve useful data such as that from low-voltage switchboards or compressors, which are often connected to the Ethernet network. This technology is ideal for monitoring slow signals (power, temperature, etc.) inasmuch as the data refresh frequency is greater than 10 minutes. It is not suited therefore to process monitoring that would need more rapid sampling.
The key stages:
The types of data retrieved and made available via the DATIVE solutions:
Energy consumption measurements (e.g., Modbus RTU):
Water consumption measurements (e.g., pulse data):
Other types of data retrieved:
