I was looking for a reason to run multiple SDRs at a time, so here's a video showing how FALCON continues to work in DragonOS FocalX w/ the LimeSDR. FALCON ...stands for Fast Analysis of LTE Control channels and works by decoding the Physical Downlink Control Channel (PDCCH) of a base station (it uses an older build of srsLTE).
** Absolutely no real cellular infrastructure was touched in this video, it's all within a controlled environment provided by SDRs and the software shown **
The video also briefly touches on how to use the LTE Cell Scanner w/ the hackRF to perform a survey in order to find information on the cell which allows us to properly configure FALCON.
Valve's SteamDeck is also shown running DragonOS FocalX in the video along with srsRan + bladeRF to run the base station, while back over on the laptop with the Lime there's a b205mini acting as the UE thanks again to srsRAN.
After everything is setup, the Lime and FALCON is used to decode the base station and show real-time usage. More details on FALCON, including it's other various command line only tools, can be found here
