Obviously, that final reach in terms of coverage can sometimes be an issue. Even if a town has good cellphone service in a rural area, when you get outside the city, it is probably not as good. Certainly I think that's well known, which is why we have the broadcast channel, the radio channel, because the propagation is usually quite good for that, but certainly just for that region.
Taking the technology and adding additional channels to meet those needs, I think, is important.
