Quote from: Undweeber on February 04, 2015, 03:42:36 am Hey everyone, has it occurred to anyone that either airports or airplanes themselves have cellphone jammers? I usually fly from JFK International in NYC, and whenever I have some last minute calls, while people fill up the plane, the com will cut all of a sudden, but not disconnect, instead I hear a terrifying noise as if someone is burning and breathing heavily, as a matter of fact the first time I heard it I was terrified because I knew my dad was driving while talking to me, I tried calling back, but I couldn't connect even though I had signal, anyways i reached him back and he was fine. The use of a jammer in-flight is next to useless as the handsets on-board will favour and register to the picocell above the ground stations due to the signal strength. It's cannot be used to deny service to a base station. There is a clause which allows a device to operate on mobile phone bands on-board an aircraft only if that device facilitates carriage services (i.e.: a Picocell). The only exceptions I'm aware of are for the Department of Corrective Services, Police and similar agencies.

the device operates within one or more frequency bands used for the supply of a public mobile telecommunications service (whether or not the device also operates within other frequency bands). the device is designed to have an adverse effect on radiocommunications or would be likely substantially to interfere with, disrupt or disturb radiocommunications and b. For example, the legislation here classifies a jammer as: a. In order for an airline to operate a jammer, that device would have to be legal in every country that airline flies to. For example, the operation or possession of a jammer in Australia is unlawful. Yes, and that regulation only applies in New Zealand, no where else in the world.
