Abstract
To ensure a high quality of service for industrial radio systems, frequency planning is indispensable. Frequency monitoring is very advantageous for minimizing possible collisions in the exchanged data packets and for quickly detecting unwanted interferers. Spectrum analyzers currently available on the market for the ISM band are significantly above the price level of the radio systems used. The measurement data and analyses from these measurement systems are also not made available online. The fast spectrum monitoring system is intended to remedy this situation. In addition to continuous online monitoring of the 2.45 GHz ISM band, it offers the possibility of providing evaluations and analyses of occupied frequency channels with low latency. In addition, detected radio systems can be quickly classified and interferers extracted. The analysis results can be transmitted directly to the operational radio systems using suitable communication interfaces or made available in the cloud for long-term evaluations. The development was based on the premise of combining this system with an IO-Link wireless system. The focus was on the rapid provision of analysis results from radio systems with fast frequency changes, as is typical for Bluetooth. With the help of this analysis data, the possible uses in the area of safety & security applications should also be discussed.
