Analysis of Different Types of Wireless Communication Modules With a Real-Time Spectrum Analyzers

At present, no matter what direction we look at or what activities we carry out, we find that we are surrounded by IoT systems. This domain has developed a lot in the last period and continues to develop in the future. These systems communicate with each other and all specialists try to improve these methods of communication through different methods and modules. These wireless communication modules used in the IoT field differ in many ways, even in terms of operating frequency, transmission distance, or useful signal detection using a recognition key between transmitter and receiver. This paper analyzes two wireless communication modules, one that communicates in 433MHz and one that communicates in 2.4 GHz and will analyze their operation using a real-time spectrum analyzer. For a more detailed analysis of these operating methods, the spectrum for the 433MHz and 2.4 GHz frequencies was analyzed with both the Spike software tool (using the Signal Hound BB60C receiver) and the portable spectrum analyzer PR100 from Rohde & Schwarz.
