I was under the impression that packet voice was used in cellular
telephone systems that are going up in some major cities.  My
understanding (which may well be way wrong) is that small, low power
radio exchanges serve little "cells" of a city, with voice being
packetized over the air to allow relatively narrow use of the frequency
spectrum and time-base multiplexing.  Does anybody have any information
on cellular radio phone systems that would confirm or contradict this?
