Sample size of one, but I clicked the article thinking that someone was using an LLM to "tune" the range performance of LoRa radio somehow. :(
Make that a sample size of two.

Is it a universal rule that higher frequency = lower range?
The range of 5Ghz is already pretty low and has trouble going through solid materials like concrete. Would 6 be significantly worse?
Indeed : radio transmissions follow Friis equation [1] -- power decreases by the square of the frequency (same goes for distance). So, going from 2.4 to 5 GHz cuts the received power at a certain distance by a factor of 2 (more or less). Assuming free space, of course : obstacles will make matters worse, depending on frequency, thickness and materials.
Meaning that going from 5 GHz to 6 GHz will decrease the range by a factor of around 1.2

Let me be a bit pessimistic amd ignorant here.
People who want to use an FPGA should learn VHDL or verilog. There have been a lot of projects to make C compile to VHDL/verilog, and it's generally accepted that it does not work very well.
What is the advantage of using Go for the same purpose?
Agreed.
However, MyHDL (www.myhdl.org) allows for programming using Python, and works very well : I haven't written any VHDL (other than at top level) for years now.
It would be interesting to see how far they can take it using Go.
