For reasons of FCC radio type acceptance requirements, I doubt that the Libren 5 will ever transmit legally below the GHz frequencies with exception of Amteur radio which is totally feasible and likely down to potentially as low as 50 MHz. In the mesh, wifi, and cell phone ranges, using the Librem 5 there is probably imminent if the FCC will license it. But why wait for type acceptance on those bands when very close by (in the RF spectrum) in each case, there is an Amateur radio band where development and actual use can begin right away without waiting for any additional licensing being needed. If we build a killer app there, commercial manufacturers will license it for consumer use… eventually. The key is to find the right modem and getting it on the m.2 adaptor to the Librem 5, and then writing the software to make it work.
