The previous version of that web page, referenced on the 3rd line of the page 
you noted, (http://linuxwireless.sipsolutions.net/en/users/Drivers/b43/) has the 
instructions for downloading that firmware on Fedora, openSUSE, and 
Ubuntu/Debian distros. You do not say what distro you are running, but one of 
those 4 should provide the rpm or deb file that you need.

We have always been hampered by Broadcom's refusal to redistribute that 
firmware, thus it cannot be put into the linux-firmware repo at git.kernel.org.

If you are unable to get this firmware through that web page, write me privately.
