Regulatory TODO

Regulatory code is maintained on the Linux kernel but a revamp of new ideas is being considered on a userspace regulatory simulator. The userspace regulatory simulator is designed to help us create / modify / simulate software changes easily but at the same time exist as a template for anyone to use the same software in any other software environment given that the license of the code is permissively licensed.

• Port to any other Operating System
• Use in firmware if needed

You can find the regulatory simulator here:

Database improvements

• Implement new regulatory interpretation rules as discussed in this thread. In summary, using the notation outlined for mathematical intervals:

   0) for all 1 <= k < n : MAX_k <= MIN_{k+1}
  
   1) each rule in the regdomain covers the frequency range (MIN_1, MAX_1]
  
   2) given C = union (over all k = 1 .. n) of (MIN_k, MAX_k] it must be
     true that (CENTER - BW/2, CENTER + BW/2) is a subset of C
  
   3) it must be true for all 1 <= k <= n:
         if CENTER in (MIN_k, MAX_k] : BW <= BW_k   
  
   4) This is easier to formulate algorithmically:
     USE_FLAGS = 0
     for k = 1 .. n
         if (CENTER - BW/2, CENTER + BW/2) intersects (MIN_k, MAX_k]:
             USE_FLAGS |= FLAGS_k

• allow for TPC
• allow for spectral power limits (e.g. 10mW/MHz)
