srsRAN_4G
Open source SDR 4G software suite from Software Radio Systems (SRS) https://docs.srsran.com/projects/4g
srsRAN is both. It includes the source for user equipment in its "srsue" directory.
Use cases are partly captured by the list of customers across the bottom of the srsRAN home page (https://www.srsran.com/). It's great for any company/research group smaller than a multinational base station manufacturer, at which size the big players don't want to talk to you.

gr-lora_sdr
This is the fully-functional GNU Radio software-defined radio (SDR) implementation of a LoRa transceiver with all the necessary receiver components to operate correctly even at very low SNRs. This work has been conducted at the Telecommunication Circuits Laboratory, EPFL.

srsRAN_Project
Open source O-RAN 5G CU/DU solution from Software Radio Systems (SRS) https://docs.srsran.com/projects/project
Project mention: Turn your Android phone into a modern ham radio transceiver | news.ycombinator.com | 2024-10-14This is a wacky idea, but the "modern" thing to do would be to repurpose seldom used 2-meter repeaters and make them 5G gNBs in the 3300 to 3450 MHz ham band (which overlaps NR band 78). Then you could directly use your cell phone (with a different SIM card) as your ham radio.
Network gaming servers to the gNBs and every kid in the US will want a ham license.

I am looking to get an RTL-SDR for my father for christmas. Is there an SDR program that I can kind of "set it and forget it" for him? He just wants a basic scanner that scans weather and nearby emergency services.
