Madhuram Mishra, Anjali Ashish Potnis · International Journal of Engineering Research and Applications · 2017
Low cost signal detection and monitoring system is designed in this paper.Wireless Transmission Monitoring is required by security agencies in order to check transmissions taking place in a particular area.In this paper Wireless Transmission Monitoring System is implemented using GNU Radio and RTL -SDR device.The implemented system is capable to monitor signals of GSM Transmission, Commercial FM Broadcast; the system is developed using Software Defined Radio based RTL -SDR hardware.Monitoring System can also be extended as a signal receiver by making certain additions in the designed model.In this paper Multiple RTL -SDR device based signal detection system is also designed.FM signals were successfully detected by the system in laboratory environment.
