===== 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:

The following regulatory ideas are being implemented on the regulatory simulator. References to code where specific changes are being implemented on the regulatory simulator are documented below as well. 


===== TPC =====

TPC is something we have considered adding but at least as per our latest review no one seems to have come up with reasons to support this. 


===== Spectral power limits =====

Its believed we may need to allow for spectral power limits (e.g. 10mW/MHz). If this is true the database may need to be adjusted to account for these. This is relevant for 5/10 MHz channels, where we currently assume 1/4 and 1/2 TX power respectively (i.e. assume a spectral power limit being reached exactly for 20 MHz channels) which doesn't allow using the full power if the spectral power limit isn't exactly that. 

===== direct database loading =====

Instead of going through CRDA, we want to load the database directly into the kernel.
Since this means a major change, a [[regdb-file-format|new, extensible, file format]] should be used.
