However, one can of course go to higher frequencies but the problem is cost. Technologies like WiMAX etc. can use higher frequencies that haven't really been used much for consumer electronics, but the drawback is that microwave componentes (amplifiers etc.) strt to because very expensive and have to be build using costly fabrication technologies.
You're still talking about microwaves though. They are still limited. There is an upper limit. You will start getting into IR and visible light. Problem is, these frequencies don't have the same penetrating power so you can't use them the same.
