Regulatory information

We take regulatory considerations seriously as its one of the major key components to getting proper vendor support on drivers. In order to enhance regulatory support we introduced a new regulatory infrastructure. This infrastructure consists of three major components:

  • Kernel integration
  • CRDA
  • The regulatory database

Kernel integration

We have factored common regulatory driver code as part of the wireless stack and provided a way for a userspace agent to update the currently set regulatory domain.


CRDA is our userspace agent which uploads regulatory domains into the kernel.

The regulatory database

CRDA requires a regulatory database (Web view or gitweb) to be build and maintained.

Sending updates to the regulatory database

If you find any errors please send them to the linux-wireless mailing list, either as patches to the db.txt file from the CRDA git tree, or just tell us what is wrong in plain English.
