It's good to see more 5G SDR for Enterprise. This will accelerate adoption.

It is now super easy to get 5G frequencies in Europe for private use. See for example https://campusnetzplaner.kn.e-technik.tu-dortmund.de/ where you buy your spectrum online in one click. In France, you can get your private N38 spectrum for 150€/month/km2

And the hardware is just as easy to build and run. With less than two cores of a low-end i5 CPU, Amarisoft stack and SlapOS edge OS, we could manufacture for Rapid.Space our own 5G base station which delivers 5G over N78. There is still enough room inside to run a software PLC next to the gNodeB. See the pictures of the assembly process and what's inside:

The PC is a standard IPC from Taiwan (Commell) and the SDR is open source hardware from FDL https://www.fdl-lef.org/projects/

I hope we will see more open source hardware for 5G base stations with different sorts of CPUs doing the radio processing (AMD, Zhaoxin, ARM, RISC V) without the need of accelerator components. 5G radio signal processing can be nowadays entirely done in software and it is not so hard thnaks to SIMD instructions found in most CPUs. I have even seen recently a sample of a fully software defined array of antenas (32T32R) with 100 MHz bw, entirely implemented with software.
