A New Experimental Setup for Collecting nRF2.4 and LoRa Devices Signatures for ....
summary
An SDR-based testbed collects IQ samples from nRF24L01+ and Heltec WIFI LoRa 32 (V2) modules using a USRP B200 driven by GNU Radio Companion on an Ubuntu 18.04 laptop while two Raspberry Pi units run TX and RX nodes. Collections use a static preamble and fixed transmit power (LoRa 20 dBm, nRF 0 dBm) to isolate device-specific RF impairments, data is validated by an adjacent receiver aligned with the USRP B200, and datasets are being prepared for ML classification.
