I used to have trouble with the badge reader
going into the underground garage at work (at
a cellular carrier no less!) while 'carrying a
call' on a hand-held cell phone, and just a few
years back when an incoming call was coming in
if I was near the PC the speakers the call would
be "pre-announced" via a low rep-rate (repetition
rate) pulsed 'thud' sound (IS-54/IS-136 TDMA
format) coming from the PC's speakers.
Also be advised that most all phones today do
the following (primarily for call delivery purposes):
a) power up registration (when phone is powered up)
b) power down registration (when phone is powered down)
c) periodic registrations (used to be every 5 minutes
here in the DFW MSA market)
d) new cell registration (while moving or mobile through
a cellular system)
(A 'registration' is a short message sent to the serving
MTSO letting it 'know' where/what serving cell site a
particular subscriber's phone is currently 'listening' to
for paging messages/calls, etc.)

Subject: [RFI] GFI/RF interference
I am on a building trades board and there is a chap who claims that a cell
phone, sitting next to a GFI, causes it to trip. Anyone ever heard of
this???? Seems strange, since I, like probably most of us, have never
tripped a GFI with rf.And we have a whole lot more than the 700mw. that a
cell puts out floating around.(the rf burns from the old am days on 160 have
healed...HIHI..)
