As I sit in my office my cell phone causes every electronic device within 3 feet to go crazy during the course of the day. Sometimes I can go for hours without a problem, then it will create chattering noises in my radio or thru my PC speakers every minute or two for five minutes. It seems this cannot be good for me. I wear my phone on my hip. Will I be sterilized? What about my head, My God, my head could be getting zapped by my cell phone. Al Qeada? On the sunny side I always know when a call is coming in. More on that later.

The phone works fine. And it's not just in my office that it causes the noise. This happens at home too. I have to place my phone 5 feet away from the clock radio on my night stand lest it go off all night. Also, when this happens it makes my monitor ... wait, there it goes again.... it causes my PC monitor to look like one of those mysterious temporal flux thingies like on Star Trek.
And another thing. Other people here in the office have the same problem.
There it goes again...
Service provider is Cingular. Phone is Nokia.

As Cingular will surely not be able to explain what the problem is. let alone have a solution, they might think about trying to sell it as a feature. Predictive ringing?

Thank God it’s not Avaya. They would attempt to charge me for it….

My Nokia does the same thing. When I'm in the car I know its going to ring before it rings because my radio goes whacky. It also does it every time it changes to a new cell tower. Seems the radio picks up on the communication between the phone and the cell tower.

With all the wireless sh___ out there, radio/TV transmitters, electro-magentic fields from power lines, TV's and computer monitors etc... we are bombarded all the time. Cell phone is just one more to the pile

I think you are exagerating just a bit. I know my Nextel (which is famous for this problem) will cause interference when it is within a couple of feet of my computer speakers and some other audio equipment but to cause your monitor to distort, I don't think so. Matter of fact I just keyed my Nextel up against the side of both an LCD and a CRT monitor with absolutely no effect.

Granted, these things adjust their power according to what cell site they have to hit. When they are at full power naturally this problem is at maximum but I have never seen any more of a problem than I have stated. ALL cell phones operate at around the same maximum power output, some less than others but not by that much.

So, if you are being accurate with your assessment either your phone has a linear hung on it or your monitor and audio gear is pretty poor.

Oops. Still trying to fugure out the qoute feature.

I did exagerate a bit. My apologies.

No exageration. If my phone is on my hip (where it is 15 hours a day) then it's 18 inches from my radio and my PC monitor. I HAVE seen it distort my monitor. No reason to make that up. What is a "linear hung"? As for the audio equipment, yeh the clock radio on the desk is a cheapy, but the Sony equipment at my house is not.

Take it in for service and get it's power output checked.

Here is the response from my Cingular account rep:
It's the RF being transmitted from the phone to the site and all of the rest of the network. There are things always being transmitted to make sure the network knows where the phone is so calls, sms, etc. can be delivered to the device. If this didn't happen, calls wouldn't be received and other problems would occur.
It happens at my home and while I'm at work. All I do is move my phone away from my desk phone or speakers and it doesn't happen. The closer it is, the more it will happen. There's nothing that can be done to keep this from happening other than placing the cell phone in a different location.

Here is my resonse to her:
I figured as much. This may have been a problem the cell phone carriers did not anticipate. If they did, then shame them. I hope they are working on a solution. If not, shame on them. Maybe you can turn this annoyance into a "feature" called predictive ringing, since we all know our phone is about to ring just before it does. Kinda like on the Beverly Hillbillies where they always knew someone was going to be at the front door when they heard that mysterious bell go off...

And yes, I could move my phone away from all electrical devices. In this case my phone would rarely be on my person as I .... oh, what the use... *richard gives up, bangs head on desk*

If you want to hear one that has even worse interference, try a cell phone that has bluetooth capabilities like for a wireless headset. They're REALLY bad.

your cellphone transmitts bursts of rf-data alot of times when you are not talking on it. It is a small transmitter so the closer to the other electronic device the worse the problem if any will tend to be. This is why electronics and cables are shielded sometimes but shielding doesn't always work so good a all frequencies, typically cell phones work very high 800 mhz to many ghz ranges. Most other devices are shielded with the idea of preventing radiation getting out so they dont interfere with other equipment, but a cell phone is a transmitter designed to radiate
rf energy. Usually the only solution to a problem like this it to try and keep the offending cell phone(s) as far away as possible from the affected equipment.You might test cell phones from different carriers whose systems operate on different frequencies (there are many) where your office equipment might be less prone to interference. As far as the tumor question its my opinion that since cell phones typically emit less than 1 watt RF power which is far below the amount thats going to hurt you. Your body is only exposed to a portion of that energy because the antenna radiates in all direcions.
