Phones that interfere with radio frequency?

Question

Just recently, I was thinking about getting a long range phone for my house since cell phones cost too much and there are too many fees associated with cell phones. When I did some surfing online, I found some phones that you could hook up to your existing phone line. However, those phones typically came from some distributor in China or some other foreign country. How do I know if those phones will work on my line? I live in the United States and I currently have verizon. What do I need to know before I actually buy one of those phones. I tried to find this information online but I was unable to find it anywhere. Someone suggested a cordless phone company, but I'm not looking for an ordinary cordless phone. I want a cordless phone that I can use several kilometers away and still make the calls on my phone line at home. Here is one such phone that I found.

Cordless phones are limited in power to comply with FCC regulations. If you use a high powered one, be sure it is on a frequency that isn't in use already. Like say, the police or fire department. If the frequency is designated (reserved) and active (traffic), you will get busted because your signal will interfere with theirs. Not to mention theirs with yours. I have a new cordless that works for about a mile. Its legal. I think it works so well because the receiver is upstairs and I live at the top of a hill.

Good luck!
