Jammer selling company?

A certain company is selling various types of jammers for cell phone, bluetooth, GPS, etc. This is illegal correct? A quote from their site: "For homes, business, clinics, movie theaters, salon, gas station, class room..etc Comes in America or Europe model, please advise your location." Isn’t htis illegal. Can I warn authorities of the site or something?
So. If that is the case, is that anything that should be done about it?

What frequency do 4g cell phones use?

I’m making a 4g jammer and I need to know what frequency 4g phones use (it’s a school project so it’s not illegal)
