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.
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 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.
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.
