Real Time Broadband Electromagnetic Spectrum Monitoring System based on Software Defined Radio Technology

This paper presents the design, implementation and testing of a broadband real-time electromagnetic field monitoring system. The system is based on a Software Defined Radio (SDR) platform that allows the implementation of three synchronous reception channels. The tests have been performed both in laboratory conditions and in case of measuring signals emitted by a wireless device connected to the 4G communication network. The results of testing showed that the system has real-time monitoring capabilities for a channel with a bandwidth of at least 10MHz.
