South Carolina Wants To Jam Cell Phone Signals

Posted by CmdrTaco on Mon Nov 24, 2008 09:22 AM
from the oooo-oooo-me-too dept.
Corey Brook writes "The South Carolina state prison system wants the FCC to grant them and local officers permission to block cell phone signals. News has been out about the growing problem of them perps smuggling cell phones into prisons for a while now. Inmates use cell phones as commerce, to implement fraud, smuggle drugs and weapons, and to order hits. Of course, some may use it to just talk to a loved one any time they can." Hopefully movie theaters and restaurants do it next.

    I must resist mentioning how in Soviet Russia, mobile phones jam you!

    In my local cinema recently, people were quite good with keeping phones on silent, but the light from people checking and sending text messages still annoyed me a bit.

    • But if you ban cell phones in prison, only criminals will have cell phones in prison!

      Our local cinema already blocks cell-phone signals. Active blocking violates FCC regs. Passive blocking is just fine per my understanding. Phones work in the lobby but drop to 0 bars as soon as you get to the hallway leading to the screens.

      The logistics of retro-fitting an entire prison complex with a passive blocking cage may be prohibitively difficult, though. In the theater, it was a design feature when it was built a couple of years ago.

        Another possible solution is to have a dummy base station that the cell phones will connect to, since it will have a stronger signal than the towers farther from the prison. If the base station is set up so as not to pass any calls on, it effectively blocks the calls. However, such a solution is currently not allowed as it would also interfere with calls for some distance around the prison, as well as the intended calls originating inside the prison.

      A 15 mW pointer laser in the face of a person waving lights around a darkened theater like that should do the trick. Everyone else will get the message, too, and you have to blind only a minimum of selfish bastards to do it. After a while, society generally will learn the lesson, and the lasers will become merely the stuff of legend.

          Anyone who has studied the eye will be quite aware that the peripheral vision is far more sensitive to changes in light, while the focused vision is more sensitive to color. There are many more "rods" in the eye, about 120 million, than cones, but the rods are not sensitive to color. They are sensitive to light. The cones are sensitive to color, but are mostly clustered in the focal area. An interesting experiment to perform is to set up a dimly flashing light in a dark room and just allow your peripheral vision to pick it up. It will appear to be brightly flashing. However, if you then look directly at it, the flash will not appear anywhere near as bright.
          So yes, the light from cell phones in the movie theatre would be very distracting in your peripheral vision.

      OK they claim they're smuggling cellphones into prisons somehow (heh I wonder if they put them in vibrate mode ;) ).

      To me the big problem really is that if they can smuggle in stuff the size of a cellphone they can smuggle in lots of other more dangerous stuff.

      I don't get why are cellphones themselves a problem, and why the solution is jamming them. After all:

      1) If you're actually going to use the cellphones to communicate wirelessly (rather than use them to play games or other stuff), they will emit a very detectable signal.

      So it's trivial to find them if they're on.

      2) It's a prison, if prisoners are not allowed cellphones, guards can probably walk in at any time, and confiscate them after detecting them by whatever means. And the culprits involved get the usual punishment stuff.

      3) The prison could put their own cell stations and listen in. For typical GSM stuff, while the comms between the phone and the base stations are encrypted (albeit intentionally weakened crypto), the comms from the base station to the rest of the network is in plaintext. No really expensive fancy stuff needed.

        Regarding your second point, I suspect that part of the problem is that, while guards are supposed to be the ones enforcing the rules, the sad reality is that guards are often part of the problem. It's well known that much of the prison drug supply comes from guards selling to prisoners, so it's not much of a stretch to think that guards might be supplying cell phones to prisoners as well.

        I think you need to watch a few PBS documentaries on prisons to understand how they work and the stresses that the guards are under.
        Also, the money that it takes to run a prison is rather high, you don't have unlimited manpower, and it's dangerous stuff. So item #2 isn't likely to happen with out about 5 other guards with you, in full gear. #3 isn't really feasible since a guard could sell access to his phone, which potentially wouldn't be closely watched.
        Your statement about the other dangerous stuff is 100% correct.

The military prisons didn't seem to have any of the problems that plague civilian prisons.

          In Illinois, the collect call rate for the prison system is $2.00 to accept a call, then 25cents/min thereafter. Criminal. The fact is, contact with outside family is the only thing keeping some of these inmates sane, and helps reduce the recidivism rate as well. These collect call rates tend to lead to phone service disconnects for the people who accept them.

          A half hour call with my brother costs more than it would cost to add another line to my cell phone plan.

          You got that right. I worked in the inmate phone racket (as a peon engineer) many years ago, when the market first opened up. In the beginning, county jails and smaller prisons were served by independent phone companies. These companies were mostly local pay-telephone operators -- a market created with the AT&T breakup -- who discovered that it was far more profitable to operate jail-phones than coin operated pay phones. For one thing, you didn't need to go around collecting the coin: inmate phones were collect call only. Secondly, they charged the highest tariffed rate: person-to-person, operator-assisted, collect with sugar on top rates.

          There was no actual operator to pay, the inmate just dialed and said his name at the voice prompt and the phone called up his mom/wife/girlfriend with the recorded message: "Will you accept a collect call from inmate x in the county jail? Dial 'one' to accept, 'two' to refuse." Even a local call would cost at least 25 cents plus $1.50 to $3.00 in fees. If the applicable tariff allowed, even these local calls were charged by the minute. An inmate's loved ones could easily get charged hundreds of dollars a month just to keep in touch. There was no warning that these calls would be that expensive.

          The jails were happy to provide this service, since the commissions they would receive really helped the jail budget. The jail operators weren't too concerned with the ethics of taking kickbacks, since it was common practice for pay telephone operators to pay a site commission to the property manager in exchange for allowing the placement of the pay phone in the store/bar/restaurant/office building/etc. Of course, the inmates were literally captive consumers. There was no other legal method of real-time communication with the outside world.

          Some places had laws that required that the commissions be used for inmate welfare and education only. And there were some particularly ethical jail administrators that also used site commissions only for benefit of the prisoners even without a law requiring it. But usually the commissions went right back into the general fund operating the facility, with the benefit that the administrator or his/her boss could spend it as they pleased, whereas government provided (tax) funding had to be spent where the governing authority specified.

          There were also "gifts" provided to sheriffs and jail administrators. These were usually "in-kind", to provide some cover from bribery laws. An in-kind gift could be an artist-signed wildlife lithograph by a well-known, first-class illustrator.

          I've long since been out of that field, and the small operators have consolidated and many have sold out to big communications firms, but the business model remains the same.

        While I agree with the premise that "it's prison, it's not meant to be fun", I disagree with your "prisoners are all criminals so lets disregard their welfare" attitude.

        In this day and age, where the legal definition of a criminal and the moral definition of one are so far divorced from one another, it really can't be taken for granted that prisoners deserve to be where they are. Remember, the RIAA wants jail time for college file sharers.

        That's not all. In prison, other things can get close to your mouth and nose you wouldn't want. That's why it's prison.

        And do you think that it is acceptable? The punishment of prison is to remove a person's liberty, not to have them subjected to sexual and/or physical assualt while turning a blind eye. Don't you think that, as a nation, you ought to be protecting individuals who are on the receiving end of such treatment or are you going to advocate torture, gladiatorial contests and being thrown to the lions as acceptable punishments?

        I am continually astounded that an advanced nation can condone such barbaric behaviour and then be affronted when other nations do not choose to follow the 'American' way.

    I work right next to SCDC's main prison facility in Columbia. Right now, the thing that really concerns us is "spillover" of this jamming into our area. We have a wifi network that we depend on (and cellphones we need, of course) and so the last thing we need is this plan having unitended consequences for wireless signals. It doesn't help that South Carolina state government has a long history of hiring shoddy technology contractors who promise the world and deliver a buggy product that only makes things worse. Jon Ozmint (the head of SCDC) has sworn that it won't leak outside of their facilities, but I'm somewhat cautious.

    The Ridegville test referred to in the article wasn't that worthwhile because Ridgeville is isolated (it's in the middle of nowhere and lagely self-contained.) The main facility in Columbia is a much larger, more wide open area located right next to the state police headquaters, Dept. of Public Safery, and several other state agencies and businesses--all of whom depend greatly on their cellhones, networks, and communications equipment. I just don't see how they could blanket that whole area and not have spillover jamming--Unless they restrict it to inside of their buildings which would mean that most prisoners would still have plenty of opportunities to use their cellphones (since most prisoners spend a lot of time outside the buildings, except for the really high-level ones)

    It's not that we're not sympathetic to the problem of cellphones in the prison system. We're just worried that they might be rushing forward with an untested and possibly ill-advised solution that could have a deleterious effect on nearby wireless usage. We're hoping they will at least give us a testing period to see its effects before they bring it online.

    What in the hell are inmates doing with cell phones in the first place?

    In an environment where even the smallest improvised weapon can be found and confiscated, you'd think it would be drop-easy for the prison to find and confiscate a cell phone. Any inmate caught with one gets n weeks/months added to their sentence... problem solved.

    Seriously - it's prison, not a Hilton, FFS - if they need to use a phone (for speaking to their lawyer, loved-ones, etc), let 'em use a POTS phone wired into a wall somewhere.

    The solution the SC prison system is looking for? It's akin to wrapping ships in Saran Wrap to fix any potential leaks - expensive and not very workable over time...

        Modern prisons (especially lower security ones) aren't built like they used to be, where every prisoner is in a cell by themselves or with a single roommate. Oftentimes there are dormitory-like conditions where a dozen or so inmates are in a room together. In addition, there are frequently common-areas (other than the cafeteria) when inmates are gathered in groups. These types of situations make it easier for inmates to hide contraband, especially where other inmates have an interest in assisting or at least no interest in actively preventing it. Add to this modern construction techniques (drop ceilings in a prison? WTF?) and you're asking for trouble.

        You can argue all day long about whether sentences are supposed to be punitive or rehabilitative, but the current situation (with regards to prison rape, drug use, and other contraband) is a direct result of these modern innovations (dorms, common areas, etc.)

        An ideal prison (IMO) would be more like Alcatraz, where each individual prisoner was kept in an separate, concrete block cell. I think if you had this kind of control, you'd be more able to do rehabilitative things (like provide access to computers, etc) whereas now the risks are too high.

        Of course, that kind of facility wouldn't be cheap, and since we're running so many prisons I don't see it happening.

    Cell phones in prisons have been big news in Texas, after a Death Row inmate was stupid enough to make threatening calls to the chairman of the state Senate's Criminal Justice Committee. They're still being found [chron.com], weeks after a supposed crackdown that turned up dozens of in-cell cell phones systemwide, along with an inordinate amount of drugs and weapons.

    The Grits For Breakfast [blogspot.com] criminal justice blog has been following the issue closely, asking questions like "Will we see prosecutions of staff who smuggle cell phones in addition to inmates and family members paying for their minutes?" Answer: probably not. Sen. Whitmire, whose family was the target of phoned-in threats from Death Row, summed it up pretty nicely at an emergency Senate hearing on the issue. TDCJ officials promised to implement a plan they'd been working on, to prevent guards from smuggling contraband to prisoners, to which Whitmire responded with a question: Why the hell weren't you doing that already?

    One story mentioned a phone that was only found by an abdominal X-ray. I wonder if it was this little bugger [thinkgeek.com]? Oh, sorry, bad choice of words.

    "Jamming" is not necessary. Everyone seems to think that blowing out a signal is the only way to get things done. That is way too short-sighted.

    It's easy to install a cell network of your own. Hell, Sprint sells 4-person personal cell towers in their stores in the US. So instead of "jamming" the frequencies, make a localized cell network that simply black-holes the unauthorized calls. This could even be adapted so the ESNs of legitimate users (guards, warden, etc) could be passed through, so everyone is happy.

    Or if you want to go the "Big Brother" route, make a localized network that snoops on all the unauthorized voice and data traffic. Seems like a great way to prove that criminals inside jails with cell phones are actually orchestrating crimes instead of just guessing about it.

  • On the cell phone issue I have first hand experience at this. A few years back, sometime after I has pissed off the local police by calling them liars on the front page of the local newspaper (and I had good reason to do this, but that's a story for another time!), they sought every reason to give me hell for years, including anything they could find to arrest me on.

    So they found a nit to arrest me on -- some unpaid fine or some such -- and they were holding me pending release as soon as some friends could bring in the money I owned.

    Alas, Bush was visiting that day and they needed the local police station for security operations. And so everyone they were holding had to be carted off to the state correctional facility. Fun stuff.

    I has asked to use my cell phone so that I could make some calls to those trying to get me out, so that they would know where to go to get me out. It was a mad rush at that police station and many of the cops there looked very distracted and confused. Since I was polite to those who held me behind bars, they granted me this request.

    They were so distracted they forgot they actually gave me my cell phone! Well, I decided to just slip it in my pocket and hang on to it.

    When I arrived at the correctional facility, they knew that myself and the other guys were coming from the local police station, so they did not bother to "pat us down". It was simply a prisoner transfer. We were wearing our civilian clothes when we arrived, and they have this elaborate process of "processing" everyone. So into the waiting room we went. Before they put us in, they made us take off our coats and dump them in piles along a wall on the floor. Fortunately, I had thought to move my cell phone from my pants to my coat pocket en route to the facility, so I dropped my coat with cell phone nicely packed inside.

    The other immates were, for the most part, behaving like civilized people. It was the prison facility that had a lot of bad attitude towards us. Hell, you'd think they were the criminals! There were cameras everywhere, and I noted the position of each and every one of them.

    So, during the process, they put us into those horrid bright-orange jumpsuits, and back into the holding area. They would occasionally allow one or two of us out to make phone calls from the payphone on the wall. Though, you needed a special number to make any calls at all, and they would limit you to a minute or so. And they were very slective about whom they allowed to make phone calls, and not everyone got a chance.

    So, I was allowed out to make a phone call and ask a question or two. After I was done, I watched all the personell and they all looked busy doing things and weren't watching me. I decided, what the hell -- I boldly strode over to where my coat was dumped on the floor, and in one swift move that would make any slight-of-hand magician proud, I swooped down and snatched the cell phone from my coat pocket without anyone noticing! 3 seconds afterwards, I was told to go back to the holding area, and I did.

    I carefully noted the layout of the holding area, which had a very big window so the personell could see us, and there was also a camera. There were about 30 or so of us in that holding area. Ah, but there was a small area near the open toilet that the camera could not see and was not in the view of the guards. Perfect! I went to that area and made a couple of phone calls to those outside to tell them how to access my bank accounts to get the money to get me out of jail! Perfect!

    Of course, other innmates noticed I had a cell phone, and immediatly I was "everyone's friend". They all began asking me if they could borrow my cell to call a girlfriend, a wife, or a mother. I was so moved by this I lent them this. I had them all stand, one at a time, in that same "sweet spot" whilst others stood watch.

    Not one single person called to make a drug deal. Not one single person called to make a hit order. ALL called family, friends, loved ones, and the like. T

      For a long time I agreed with this but then I realized the last place I want my phone blocked in an emergency is someplace with minimum wage workers (and probably managers.) And as obnoxious as a phone is in the theater, those are the same idiots who talk to the people they come with during the film anyways.

      I wouldn't. A friend of mine worked for the Red Cross, and was required to keep an emergency phone on her at all times when she was on-call-- and those on-call periods could last upwards of a week. Or how about a doctor who needs to be accessible immediately, but also has social obligations?

      We don't need jammers in theatres and restaurants. What we need are old-fashioned ushers, and old-fashioned shaming. Some asshole keeps lighting up five rows down? Shout at him to quit it. If he gives you guff, go to the manager. You'll probably get a free ticket out of the deal, and he'll get turfed. If you're at a restaurant... well sorry, but you're at a restaurant. People socialize over food.

        I am sure that friend was not allowed to do a lot of other things. Sorry, you are on call, that means you are not able to go to a restaurant or movie. Tough luck. Talk to you employer for compensation.

        The doctors I know all turn off their phone during the movie. OTOH they also send text messages to each other during operations, where mere mortals are not even allowed to turn on their phone. (Yes, during the operation.)

        Restaurants do not give much problems here. People take the call outside after the phone was set to vibrate. If they would be on call, they would go outside every 30 minutes or so (like the smokers) and check if they have a message.

        Doctors on emergency call that I know would not go to dinners, but stayed at home. They would do the same if there were blockers.

        If those people do not like it, take a job that does not require you to be on call. I should not suffer from your career choice.

        Well, what we really need is more responsible people that think about other people around them a little.

        Unfortunately, that is outside of your or mine or the theater management's area. We can't change those people. But we (that is, one of us, the management) can put in jammers.

        It's not the perfect solution. But if the perfect solution is theoretical, a good practical solution will do.

      I'd say don't bother with blocking cell phones, let the inmates have as many as they want.

      Just make it a death penalty to be caught in possession of a charger.

            And why not intercept all calls by setting up a prison-wide base-station? Use the ECHELON system or something to take care of the intercepted calls.

            You know this is an idea I could really get behind - microcell equipment for office buildings, etc. has reached quite an affordable level and wouldn't really be more than a drop in the bucket when it comes to a prison budget. This way guards, staff, and visitors could still use their cell phones -- perhaps when you arrive at the prison check-in desk you give them your cell's ESN - they enable it for 8 or 12 hours through their microcell - you can make all the calls you want, etc. If you slip the phone to a prisoner or whatever, they are cutoff within the day and the phone is useless. Obviously all phone numbers "from and to" will be recorded - and you can be informed as such when you give them your ESN to get service within the prison.
