[Lowfer] Cell Phone Freq standard

[Dave Brown]

Mike-
They have had a paper (PDF doc) on this topic available on their web site
for some time-well over a year.  I presume it's still there-

http://www.endruntechnologies.com/pdf/PTTI2001_WhitePaper.pdf

You need CDMA network coverage and a CDMA phone, not an AMPS one. And this
asssumes the phone CAN be hacked to get the appropriate signals- not many of
those are getting are tossed out over here yet, and I'm not sure a standard
phone produces the required sigs in a readily available form either.  The
few I have seen inside are so 'integrated' that hacking into them looks well
nigh impossible. But the block diagram in the above paper looks relatively
simple-(don't they always!)-so maybe someone will have a shot?
