In the United States, the Federal Communication Commission (FCC) allocates the RF spectrum to various services. Each country has a corresponding regulatory body. Internationally, the International Telecommunications Union (ITU) works for common and consistent standards and allocations among countries. Radio waves don't honor national borders.

Depends upon the country you are in - there is a regulating body for each country that also regulates agreements with bordering countries insuring that Steve Wright in the Afternoon doesn't interfere with Hans Schiffers.fm (they wouldn't anyway because the BBC FM signal won't reach the Netherlands and vice versa).

For transmitters like BBC Radio 4 (long wave) there are similar agreements but these are much further reaching - Radio 4 is receivable in most European countries due to the inherent qualities of a long wave signal. Even good old medium wave (OMG I remember Radio 1 when it was ONLY on 247m - no FM) is subject to "skip" at certain times - Radio 1 at night in France was a possibility and I am sure many will remember the whistle and pop of Tony Blackburn on Radio Luxemburg broadcasting over MW.

Sorry, but you are not in charge of the world you ****.
Cell phones are regulated by the electromagnetic spectrum but only the **** questioner knows the answer. Why does he ask?

first off, the question is a bit vague. of course the region of em spectrum involved in cell phone use is mainly the radio waves but other phones also make use of infrared. if this isn't the answer you need, please clear or add more explanation about the question.
