that's not redundant. two different sites, with different coverage
areas.

redundant would be if there's a sprint and t-mobile cell site at the
*same* location, at which point they might disable one of them. they
might also choose to keep both for additional capacity, depending on
usage patterns. they might also tune it cover certain sectors, such as
one north and the other south.

i'm not talking about maps.

that does not make any sense.

redundant radios can be repurposed as a spare or deployed elsewhere
where it's needed.

the point is that they are not necessarily redundant.

amps roamed among various carriers in either a or b.

initially, roaming had to be activated when arriving in the new area so
that calls were forwarded to the new location (don't remember the
*code), then it became automatic upon first connecting to the tower.

there was also an inbound access number, usually ending in x7626, the
digits corresponding to 'roam', so that people could make a local call
to connect to a roaming customer who had a long distance number.

where 'reprogram' is a *code to tell the system to forward calls.

cdma roamed without the user doing anything.

some people lump everything into gsm, but that's technically wrong, as
they are separate protocols and air interfaces.
