Re: [Phys-l] an all-too-predictable blackout

Joel,
I wonder if the sampling rate used to squeeze the phone calls into the available bandwidth is hampering the fidelity. I don't know what that is, but maybe our resident Bell Labs guy can help with some technical info.  Better fidelity would require better sampling which would reduce the # of simultaneous calls on a channel.  That means more infrastructure/cost per call.

If you want to pay for a Yugo, you get a Yugo.  If you want to ride in a Mercedes, you pay for a Mercedes. Who has the hifi cell network?
