Spectrum monitoring is a field of research that focuses on the analysis and monitoring of the electromagnetic spectrum, which includes radio frequencies used for communication and other purposes. This research area involves the development of tools and techniques for monitoring and analyzing signals across the spectrum to detect and identify sources of interference, unauthorized transmissions, and other types of signal anomalies. Spectrum monitoring is important for ensuring efficient and reliable communication systems, as well as for regulatory purposes to enforce frequency allocations and prevent harmful interference. Researchers in this field work on developing algorithms, software, and hardware solutions for spectrum monitoring, as well as studying trends in spectrum usage and developing strategies for optimizing spectrum utilization.
