Re: seen anything like this before?? block all cellular radio activity
Now I do have a device that will jam Sprint signals. I turn my Airave private and unless your number is listed, you will hear the message that you are in a private network, please back out and try your call again. LOL

That is banned in the US. Imagine somebody needs to call for an emergency.

this isnt really the same as cell jamming, not in the context of the law anyways.. unlawful cell jamming im pretty sure due to the legal language, means you have to "broadcast" a signal to jam.. this wouldnt be crossing that line by legal definition... ill see if i can find more info i suppose as im not the foremost authority |

You dont need to turn off your phone or your radio on theaters. Just need to silent the ringer. You don't have a signal when ur 50,000 feet inside the Plane. The only agency allowed to use jammers are the military for a reasonable cause. Don't you even realize that the idea is so cool, U can only get it in China?

Re: seen anything like this before?? block all cellular radio activity
I am not one to post like this typically but this is something I am interested in,
A theater could easily construct a inexpensive faraday cage during construction and remodels of theaters which would make it impossible to acquire a cellular signal. To do so would not be in violation of the Communications Act of 1934 otherwise known as Chapter 5 of 47.U.S.C. § 151 as it is only illegal to produce an wireless signal which interferes with another licensed service. Hospitals could do the same but they would not because of paging services. You would have a signal at 50,000 feet as FM radio is line of sight and considering most cellular towers produce between 10 and 100 Watts PEP. The reason the FCC asks that mobile phones not to be used was because originally when mobile phones used 3 Watts of power they would cause problems with multiple towers considering the line of sight advantage, when digital communication became the norm the concern was one of channel reuse. The FAA was initially concerned about instrumentation issues which have been disproved using existing handsets. Several airlines are investigating the use of picocells pending FCC and FAA approval. Regarding cellular usage, the Federal Government is allowed to block radio traffic via the National Security Act of 1947. I have been in numerous federal facilities where mobile phones were not allowed. As for the case, who knows? All I can say is I appreciate the freedoms afforded to me by the Constitution. |
