That may be true but to use it that way legally you would need an
amateur license, and this is not just a paperwork exercise, you have to
pass FCC exams covering electronics and radio theory (plus laws and
regulations) to get one. For most people, it's not an option.


And when you do get that license, you are, by lay, limited on what you can
communicate.

IMO. boosting your home wi-fi unser the auspices of an Amateur Radio
License is a no-no.
