On x86 systems this blob is typically provided in a UEFI variable (but not found automatically by the kernel, so you need to copy it from the UEFI variable to /lib/firmware). On embedded devices it needs to be provided by the manufacturer (not Broadcom, but the OEM vendor) of your wlan card (respectively the devboard). Regards Stefan Lippers-Hollmann [1] These blobs contain calibration data, regulatory domain settings and similar information, which is highly specific to your exact device. Using data from a different device would make it run out of its specifications (getting you in trouble with FCC, ETSI, etc.) and could even physically damage your device.
