Xbox 360's Jamming Wireless Signals? 222
WirePosted writes "A report has emerged suggesting the Xbox 360's inbuilt wireless system for communication with wireless controllers and headsets is transmitting over a wide area of the 2.4Ghz spectrum, causing interference to WLAN's and other 2.4Ghz devices."

Something along the lines of:
(1) Tolerate interference from other devices. (2) .... something else that I forget....
You see, the FCC does not want to have to certify that each and every $3 wireless mouse keeps its emissions within 0.2 KHz of 945.343 MHz at a field strength of no more than 330 microvolts / meter.
Welcome to the Republican Spectrum of the Future.

Holy cow.
1) It's "sine" wave, not "sign"
2) A digital signal (as in a square wave) is a composition of sine waves. There is no "signal distortion" due to the "nature of the produced sign (sic) wave". And a pure sine wave at a single frequency has no (theoretical) distortion.
3) "Bleed over" is when the harmonics of the signal that fall outside the desired band are of sufficient amplitude to cause a problem. Proper engineering mitigates this effect. It has nothing to do with the "nature" of produced sine waves.
4) Oh, and in case anyone's wondering... If a pure sine wave gets clipped, it's no longer a sine wave. It's another waveform composed of another set of sine waves, mathematically an infinite series.

Well the whole thing says:
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
The part that you forget is the part says "this device may not cause harmful interference". I'd say that this is pretty relevant.

Wouldn't it have been better to say "I hate everything that's unlicensed wireless"?
I've never had an interference issue with a cell phone. Of course my cell phone is using a licensed band......
This is the single reason why I've never bought a bluetooth headset. Yet another device to charge. Somebody needs to give me a rational explanation for why mini-usb hasn't become the charging standard across the industry. Motorola is using it for all of their stuff (phones and headsets). Why is nobody else? Yes, I mean you Nokia.....

Here's the cold hard reality. It takes many years to become an electrical engineer and comprehend the math that explains why your original post was naively silly.
As others have pointed out, it's embarrassingly obvious that you don't know what you're talking about. And that you're not a EE. So don't pretend to be one. It just makes you look like a fool.
