LoRa vs MYTHINGS
A Comparative Study of Quality-of-Service Under External Interfernce
This study was conducted by Professor Dr. Thomas Lauterbach from the Nuremberg University of Technology for Applied Science. It evaluates and compares the Quality-of-Service of LoRa vsbetway下载(MIOTY/TS-UNB) under real-worldinterference conditionsequivalent to an Industrial IoT environment.
The performance of both networks was evaluated byPacket Error Rate(PER), which signifies the percentage of failed messages.
Results showed that in an ideal environment (e.g. laboratory) where no interference is present, the two networks performed almost equally. However, in real-world contexts with significant interference from co-existing radio systems and connected devices,MYTHINGS has considerably higher interference resilience than LoRa. At the same network range, LoRa loses a significant percentage of messages while MYTHINGS does not lose any.
The Importance of Reliability in Industrial IoT
The importance of industrial-grade reliability cannot be overstated. Because of mission-critical applications like environmental monitoring, predictive maintenance and worker safety,the Industrial IoT sector demands a packet-error rate of less than one percent.High reception rate and minimal packet loss ensures important data is accessible; providing thebusiness intelligence needed to improve operational efficiency across an entire campus at the lowest total cost of ownership.
For LPWAN technologies operating in the increasingly congested, license-free spectrum, interference resilience is a prerequisite to ensure high reliability. An LPWAN’s technical design determines its ability to avoid interferers or packet collisions when the traffic is high, thereby improving overall reception rate.
