IIoT Study Compares BehrTech Platform Against LoRa LPWAN

BehrTech, a wireless connectivity provider for the Industrial Internet of Things (IIoT), has issued a report evaluating and comparing its MYTHINGS platform with LoRa LPWAN platforms under real-world interference conditions. Dr. Thomas Lauterbach, a professor at the Nuremberg Institute of Technology, conducted the independent study, which was commissioned by BehrTech.

According to BehrTech, the results showed that in a real-world Industrial IoT environment containing high levels of interference from other systems and devices, MYTHINGS offers higher interference resilience than LoRa technology. At the same network range, the firm indicates, LoRa loses a significant percentage of messages, while MYTHINGS reliably transmits all messages.

"In the dense interference scenario, there was a significant difference in the quality-of-service between MYTHINGS and LoRa," Lauterbach said in a prepared statement. "Observing both networks at the same signal power, MYTHINGS successfully delivered all messages while the LoRa network lost more than 10 percent of its messages. Even when signal power was increased, there was a four to five percent packet error rate in the LoRa system."

Using a LoRa EU-mode MultiConnect Conduit IoT Starter Kit and the EU-mode MYTHINGS by BehrTech Starter Kit, the study evaluated network performance throughout both a 60-minute period and a four-hour period under various external interference conditions based on the LPWAN Interference Model Standard developed by the IEEE. Results were measured by packet error rate, referring to the percentage of unsuccessful message transmissions. Four interference scenarios were used to demonstrate different levels of signal density. The study focused on a dense level scenario that has an interference level equivalent to real-world Industrial IoT environments.

"Data is the lifeblood of Industrial IoT and with the ever-increasing number of connected devices in Industry 4.0, interference resilience is paramount to successful IoT deployments," said Wolfgang Thieme, BehrTech's chief product officer, in the prepared statement. "MYTHINGS was purpose-built to withstand the significant interference that exists in industrial environments and to provide the robust and scalable future-proof connectivity needed for next-generation IoT networks."
