RF Surveillance Node

Radio Frequency Surveillance Node

Different nodes sends signal based on pre-configured required power strength. Each node can have unlimited antenna scanners; each antenna is given a range of frequency slice to scan and report the power which exceed the given threshold. Threshold is defined in a setting file. The antenna sends the signal data into a transmitter device found in the node. The sent data consist of a central frequency in MHz , the power in dBm, IQ sample (imaginary number) where the sample size is configured. The sample size can be in hundred thousands. The sample rate is 1.24 millions samples per second; it can be configured to tens of millions per second. The node works in a plug and play. High quality SDR devices (RTL-SDR, USRP, BladeRF, HackRF etc..) can be attached to sample on much higher rate.
