Justin Callaway’s Cingular cellphone sent radio interference that destroyed one of his prized speakers, so he made an awesome music video about it.
For those that don’t know, some Cingular phones using the GSM system have this problem where if the phone is near a tv or speakers, before a call comes through you will hear a tkktktktttt through the speakers. In Justin’s case, the interference sound blew out his speaker. Probably because he had it turned up high while working on an audio project, but that still doesn’t make it ok. Cingular doesn’t warn customers before they buy about the RF interference, either.
Full of a rampaging evil Cingular logo, exploding electronics, and sad speakers, this is one of the most impressive consumer-revenge art pieces we’ve seen.
Justin is hardly alone. Cingular cellphones spewing RF interference is well documented and complained about, isn’t the FCC supposed to regulate this?

Feeling Cingular [Official Site]







I hear Justin’s pain. My Cingular Nokia 6102i hates most all audio devices, including:
- Radio Shack Pro-95 police scanner
- Sony alarm clock radio
- Conference room speakerphone
- B&W CM2 stereo speakers
When driving around, I can tell whenever my phone switches cell towers as it tkktktktttt’s through the Pro-95. I have to use strategery when placing my phone anywhere close to the alarm clock on my nightstand, or else it will wake me up when sqwaking with the network. My co-workers constantly give me the stink-eye in meetings and love to say “Is that your phone?” when the conference call speakerphone starts alerting all to an incoming call. And, now, I can’t get too close to my home stereo for fear of having a Justin-esque asplosion on my sweet, sweet B&W’s.
And my old AT&T TDMA Nokia 6560 never made a peep.
Since I had been originally thinking my wifes radio was defective I hadn’t thought to see if it was her Cingular phone. I contacted them yesterday about obtaining a replacement and they basically said tough luck. You can pay full price for a new phone or whatever.

Dear Mr. XXXXXXXXX,
Thank you for contacting Cingular Wireless with your questions regarding
the replacement of your handset due to the interference received on your
car radio when the service is used. I do apologize for the
inconvenience this issue has caused you and I will be happy to assist
you today.
The signal for wireless phones is, in essence, a radio signal and can be
affected by the same structures and interference that would block a
radio station signal. Please know that network signal strength can
depend on a variety of factors, including weather, terrain, building
structure interference, call demand and your device and when the service
on the handset is used near a radio which is being played, the
interference that you are hearing will most likely occur. This can also
happen when using the handset near a microwave. Because of the many
factors that can affect cell phone signal strength, we are not able to
guarantee 100% coverage and we would not be able to allow an early
upgrade due to this issue.
As your handset will not be eligible for the equipment upgrade process
until 09/16/05, if you wish to make the purchase of a new handset at
this time you would need to do so at full retail cost. As this type of
purchase cannot be made through your online account due to the pricing,
you would need to either visit your local retail store, or call Customer
Service at 1-800-331-0500 for assistance. The representative that you
speak with would be able to advise you of the current retail pricing at
the time of your inquiry. Since the equipment pricing is subject to
change at any time, we are not permitted to quote the pricing via email.
Again Mr. XXXXXXX, I do apologize for the inconvenience and frustration
this issue has caused you.
We encourage you to visit our web site, http://www.cingular.com, often to view
current and previous monthly statements, make payments and to shop for
new product and service offerings. If you have any further questions or
concerns please do not hesitate to contact us. We do appreciate the
fact that you have been a valued customer with us since 12/16/05! Again
Mr. XXXXXXXXX, thank you for contacting Cingular!
Sincerely,
XXXXXXXXXXXXX

This is why when I mix sound I try to tell everyone to turn their phones off (band, techs, everyone near the equipment. Not that we’ve had issues, but at least it reduces the possibility. On older equipment I’ve heard the noise pretty good, but a lot of the newer equipment has an easy time with it or no issues at all.
If you think a GSM handset causing a buzzing in your audio system is bad, imagine the amount of interference Nextel’s iDEN cell sites are causing our nations’ 800MHz public safety radio systems…it’s akin to a loud roar of a jet engine in your ear and trying to listen to your grandma’s clock radio from across the room. So now we’re shuffling the whole band and it’s going to magically fix it…iDEN is an old early 90′s technology and no one considered the effects of it on existing radio systems.
Ergo, GSM (2G) dates back to the late 1980′s, and an old air interface like this was developed when not every 9 year old had cellphones and yakked on them for hours on end. We also didn’t have masses of electronics around the house. One must also take into consideration that older consumer electronics built “back then” was usually over engineered compared to todays stamped out everything on a chip in an el cheapo plastic case design.
FYI CDMA transceivers (such as those used by Verizon, Sprint PCS, Alltel, US Cellular, Cricket and Metro PCS to name a few) don’t cause RFI to devices because their transmitters don’t pulse rapidly and they are spread spectrum in nature so their RF output is spread across 1.5MHz (CDMA2000) channels. CDMA was chosen for the 3G GSM standard as an air interface, so theoretically a Cingular 3GSM phone operating in a 3GSM areas shouldn’t wreck your precious speakers.
Or you could just follow the manufacturer’s instructions and not place radio transmitting equipment near your audio amplifiers, TV’s or speakers.
Cellphones are just two-way radios…do remember to turn them OFF in hospitals, near blasting caps, or when near a terrorist bomb or explosive device.
