Please educate me.
Why does my cingular phones cause so much interference with other devices (tv, radio, pc, etc.)while I'm on a call? I am f-ing sick of it! I thought this would have been improved with the merger. Is that just a gsm issue? My current Verizon service nor former sprint service has never done this.

Correct! only GSM does this, CDMA doesn't do this. I guess that's another difference between the two. âšī¸

actually, nextel's iden does it also. It messes with monitors, speakers, landline phones, you name it. I think it's the 800mhz spectrum that does it.
...
Funny, my Samsung E105 only messes with my computer monitor if I have the handsfree kit on it... otherwise, it's fine... Of course, it's only using 1900Mhz so maybe that's the difference.
...
I did notice that about Nextel service also. The only link I can think of is them all using sim cards. There has to be an explanation for this.
...
Isn't iDen based on TDMA? -Ithink i heard that somewhere, I really don't know/care too much about iden- I think this is why...
...
iden is actually more based on gsm I believe...which is why I wonder why everybody keeps saying nextel will be "upgrading" their technology by using sprints cdma....
...
The word upgrade is a marketing tool. It feels good to customers. We use it all of the time to get people to migrate to Cingular.
...
No, I'm talking about comments people have made on these forums...don't think you guys are trying to market anything to me. And seriously, I think it's just the 800mhz band causes too many problems...

You know, this has been happening to me ever since I got my first first generation digital phone(NOKIA 2160) with AT&T Wireless. I experienced the same phenomenom with my Nokia 6160.
I am experiencing the same thing with my ATTWS GSM Nokia 6200 and my mothers GSM Nokia 3595.
It's true.....you do not experience this static with CDMA. When I worked at Verizon Wireless (as well as at ATTWS,) if I had my Nokia 6160 on my desk, I would hear static in my call center headset whenever the phone went into sleep mode or when I received a call or received a text message.

That's the 850mghz updates and so forth coming to and from your phone.Only GSM phones do this. Spooky aint it?

My VZW phone would create interference with my friends CD player car kit. Everytime a call came in, a loud screeching/humming noise would come from the car speakers. I think it may have created some resonance that affected the magnetic strip on the tape adapter.
...
That might be it. I knew I heard something about SIM-free GSM technology. Kinda like sugar-free but without the nasty aftertaste. đ

It's not just 850 MHz GSM phones and in fact any time division RF interface, such as TDMA. The "noise" you are hearing is common and "normal" for all GSM platforms. GSM employs frequency hopping and time slotting to minimize co-channel interference and data corruption. GSM phones transmit about 1/8 of a time slot, the constant "on" and "off" transmission creates that pulsing noise you hear on nearby equipment, the effect is worse than TDMA and caused by the frequency hopping technique.
The reason you hear or see those pulsating noise is because that the affected equipment is poorly shielded. The "noise" can get even louder if you have a weak signal (either because you are far from the nearest site or you have other GSM phones transmittin...

The interference from GSM and TDMA is often both radio frequency (RF) and electromagnetic (EMI). An alternating current is induced in the wires of the GSM or TDMA phone due to the alternating draw on the battery and will create EMI if no magnetic cancellation techniques are used inside the phone. CDMA (Code Division Multiple Access) phones are more consistent in their power requirements.
What's required to shield against RF and EMI is quite different. Phones willl also be quite different in whether they're designed to reduce the EMI generated by the battery; many phones have not been well-designed in this respect.
GSM and TDMA phones will also often cause interference with older hearing aids; someone wearing a hearing aid next to a GSM...

no actually gsm since the frequcies that it works on it interfered with alot os signals such as tv. radios ETC the reason digital doesnt do this or as muchis becasue sigital is working on a lower bandwith so it doesnt have the ability to interfere being lower signaled... some sigital phone though however will do the same thing
