FCC Issues Forfeiture Notices to Two Business for Jamming Cellular Frequencies

An anonymous reader writes "The FCC, responding to anonymous complaints that cell phone jamming was occurring at two businesses, investigated and issued each a Notice of Apparent Liability for Forfeiture and Order (NAL). You can read the details of the investigation and calculation of the apparent liability in each notice below. Businesses engaged in similar illegal activity should note the public safety concerns and associated fines. From the article: 'The FCC issued a Notice of Apparent Liability for Forfeiture and Order to each business: The Supply Room received an NAL in the amount of $144,000 (FCC No. 13-47), while Taylor Oilfield Manufacturing received an NAL in the amount of $126,000 (FCC No, 13-46).'"

      Should you have a right to use a radio on my property?

      This is different than a place of employment and I'm not speaking of places generally open to the public. I'm strictly speaking about my property - we can even limit it specifically to an area centralized around my living quarters so as to avoid any blocking from overlapping onto neighboring property. There is no situation where ones blocking should be allowed to impact neighboring property.

      Now, I can't think of a legitimate reason to block RF on my land or anything like that - but that's not the point. It seems that I tend to take a rather heavy handed approach when it comes to personal freedom and property rights.

      I'm not attempting to be negative nor am I attempting to start an argument. I am unsure of what to think and thus my question - I really don't know. As the spectrum is considered communal property and is regulated as such there is the argument that restricting someone's right to their property (the spectrum they're allowed to use legally) is wrong. Yet, for some unknown reason, one may wish to prevent people from using a ham radio, CB, etc on their property and actively seek to block it. Should they be allowed to do so? Should they be allowed the right to prohibit radio communication from their property?

      I don't really know - I am leaning towards a, "Yes, they should be allowed to block it on their own private property while assuring that none of their blocking methods impact any portion of neighboring property." Again, I can't think of any logical reason why someone would want to block that so I'm mostly curious as to your (and other people's) opinion on where the line should be drawn.

      In fact, all I can picture is some hillbilly drawling out that he "doesn't want none of your radio frequency being utilized on this here property." It's ridiculous at face value but the question remains the same where freedoms are concerned.

      Also... We already have national radio quiet zones where anything of the sort is expressly forbidden but I don't think that the reasons they are allowed to enact such regulations apply to private property very well and they aren't actually blocking RF so the two aren't really related. *just wanted to cover that to avoid potential confusion*

By having side-tone we have feedback relating to how loud we're talking and the signal going to the other end. Without the side-tone, there is a natural tendency to talk louder. I don't know why cell phone designers have not incorporated side-tone. The amount of power it would consume is very small.

    "I think cell phone jamming should be legal."

    If you have an indoor business, there is absolutely no reason to "jam" signals. You can block and ground them instead with a Faraday cage. Just make sure your walls and ceilings are lined with chickenwire (should work fine for cell phone frequencies), and make sure it is all grounded. Voila. Cell phone no worky.

    There is a very big difference between BLOCKING cell phone signals and jamming them. Blocking is legal. Jamming is not.

    The 'simple' solution to this problem isn't tin foil or expensive infrastructure replacements.

All phone sellers will immediately embrace it if there was a law in the US (even a single large state's law maybe).

    Jammers would probably not be illegal if they respected property boundaries. I totally agree that you should be allowed to do what you like on your property. But you may *not* do what you like on *my* property. Running a jammer on yours will likely kill the signal on mine. So install any passive blocking you like. Once you go active and affect people around you, that's where you're stepping outside the bounds of personal freedom. Using your example you say that people may die due to the small delay while someone steps outside or disables the jamming device. But what about situations where your location isn't the one doing the jamming? Does stepping outside get you closer or further from the jammer? There certainly will be no way to disable the device since you have no idea who's even running it. That small delay suddenly can get pretty significant...
