Don't rightly know - I think they use the same base/repeater scheme as other
cell phones so to my knowledge they are not using any dedicated frequency.
But then, I'm just a casual amateur.

The interesting thing about OnStar, when you first contact them to set up
your vehicle and account you do it by pressing the blue OnStar button in
your vehicle. They then ask you for such information as your name, home
address, home phone, credit card number, CC security code, your occupation,
where you work, and they ask you for an access code and password to ensure
you are you when you need help. All that information is dutifully repeated
back to you by the OnStar representative, for accuracy, so the information
is aired twice.

Gives me warm fuzzies!

this must be a reprint from back in the early 90s ........

dunno where " YOU " live , but in my west coast metro
area of 1.2 million population, you could count " all "
the daily " analog " cellphone traffic on your fingers and toes.

99.9 % of all previous analog cell calls have been switched to
digital, out here, and there is pretty much " nothing " of ANY
substance to be found on the analog cellband anymore.


Except for OnStar. That great GM feature uses analog, at least here on
theWest coast.
