Yes. That can be quite effective. I will be writing one. They do not have to attempt this on 900Mhz. And they shouldn't, unless they can do it in a way that does not disturb considerable use of the spectrum present today. And perhaps they can! The EU got along with US gps. I bet this can be done here too, no private spectrum required.
