It is my understanding that most USA carriers only have "interest"
in amps because the FCC still requires them to. If I recall correctly
in 2007 there will not be that requirement. I think most amps systems
will be shut off that year.

My understanding is that the FCC's coverage requirements will remain the same.
So, AMPS will go away only if another technology can cover all of the same areas
(most of the rural USA) at least as effectively and economically. Australia's
experience indicates that CDMA *can* be cost-effectively adapted for covering
large sparse areas, whereas GSM cannot. Thus, in the USA we may end up with a
situation where the 800MHz CDMA carrier in each area eliminates AMPS entirely
because its CDMA can substitute, whereas the 800MHz TDMA/GSM carrier must
continue to provide AMPS because it has no reasonable substitute.
