Default PC speaker buzz from Cingular GSM cellphones

This is normal. Just keep the phone away from the speakers.

In my office we often experience instances of a "galloping" sort of buzz
periodically coming from the PC speakers near co-workers who have Cingular
GSM cell phones. A preliminary Web search turns up many instances of this
problem. My understanding is that these phones periodically communicate
with the network, and during these brief bursts the carrier is modulated
at around 200 Hz resulting is a clear, repeatable buzz pattern. How is
this buzz getting into the PC speaker amplifier, and, more importantly,
how can it be prevented?

Thanks,
Doug

No, this is NOT normal. This is stupidity on the part of whom ever came up
with the GSM standard... Any NORMAL person, business, corporation, etc.,
would have properly tested for interference potential prior to releasing or
even accepting such a standard.

Yes, it is normal. The PC speakers are not bypassed for the RF the phones
generate. They save a few cents by not doing this. There is nothing wrong
with the phones.

I agree, this is normal, and FCC rules say it's the speakers
responsibility/fault to protect themselves from the RF. Not the phones
responsibility for the speakers being unprotected.

I agree, there is nothing wrong with the phones, it's the GSM standard, like
I stated in my previous posting. I still don't believe that there is
anything 'normal' about WILLFULLY causing interference. It's not just
speakers, it's damn near everything. While I DO agree that things should be
shielded better, that's no excuse for adopting a standard that they KNEW
cause all kinds of interference. If it was something minor, sure, that
happens everyday, but this standard is a MAJOR source of interference.

With replies like yours, I would guess that BPL is OK in your book too?
It's not the fault of the internet service, it's the fault of the radio,
etc. manufacturers for not having proper shielding or filtering. Yeah
right! Sorry, your argument doesn't float with me...

I'm not so sure that GSM would be any different than any other cell standard
that allows communication with towers several miles away. I'm pretty sure
even an old AMPS phone would do interfere about as much, with a
different.sound. We just had less electronic junk back then to interfere
with.

By the way, "... stupididy on the part of WHOever came up with the ..."
would be more correct.
