The linux wireless regulatory database
regulatory.bin is the file used by the Linux wireless subsystem to keep its regulatory database information. It is read by crda upon the Linux kernel's request for regulatory information for a specific ISO / IEC 3166 alpha2 country code. The regulatory database is kept in a small binary format for size and code efficiency. The regulatory.bin file can be parsed and read in human format by using the regdbdump command. The regulatory.bin file should be updated upon regulatory changes or corrections.
The regulatory database is maintained by the community as such you are encouraged to send any corrections or updates to the linux-wireless mailing list: [email protected]
