Re: Nice Scam by Cingular
said by Albertcrombie:
Sure, so whenever I turn my cell on and place a call next to my computer monitor (75Hz) and the screen becomes blured momentarily it is because of my girlfriend's hairdryer, right?
Oh and what about when i move my phone next to my speakers and I hear this weird intermittent noise ?? Your laptop is not even close to being shielded as well as the avionics in a typical aircraft. The interference is from low level harmonics and the circuit paths in your unshielded laptop are acting as a small antenna.
Aircraft electronics have to be highly shielded to protect against other system on the aircraft.
Aircraft transmission and receiving systems are also very, very selective in the frequencies that they allow to pass and odd harmonics are not on the list.
Besides, you 75HZ laptop screen is operating at a much higher frequency. The 75HZ is simply the refresh rate and is the number of times a second the screen is redrawn. Has nothing to do with the internal operating frequencies of the laptop.
Your statement about the laptop 75HZ, and your girlfriends hairdryer (motor with brushes that produces lots of harmonics from the slight sparking of the brushes) indicate that you know little about radio frequencies and how they work.
If an airplane can tolerate a lightning hit with more than a few watts of power (1.21 gigawatts according to Doc Brown), your cell phone is not going to be a problem.
The experts know and if there was even the slightest risk of compromising aviation electronics cell phones would not be allowed. |

Long Beach, NY | giga stands for 10 to the 9th power.
In the above example, it refers to 1,2100,000,000 watts. |

Perhaps I should have written it a jiga-watt and perhaps it would ring a bell if you were to go back to the future. |
