Maybe somewhere that would be a concern but not in the US. By being present on the private property (especially if there was any barrier to entry such as a basic fence) would be sufficient to negate any expectation to privacy. If you walked into someone's home and started yelling secrets, you would likewise not be granted any privacy protection. Your cellphone is essentially doing just that but in RF instead of audio waves.How do you ensure everyone whose device connects to the monitored network is aware of the monitoring and has agreed? I would think you'd need 100% acknowledgement for something like this, especially at a private facility.
SNITcH!"911? Hi, there's a truck with a ladder on it parked at the back wall of the State Pen!"
Call failed.
That's right, though less of a cell tower and more of a carefully laid out mesh network to ensure the private network signal is dominant within the sublease area and is minimal outside it. I posted a white paper up thread but it seems like the FCC made rules back in 2017 that require the spectrum holders to cooperate with prisons for this purpose, so I suspect the lease terms are fairly reasonable, if nothing else but to avoid giving ammunition to those trying to push for dumb RF jamming.Time to put on my spectrum nerd hat here.
One of the interesting things not noted is this article is that the best I can tell, its not Verizon or the other cell phone carriers that do the Managed Access Systems.
It appears to be other companies that lease the spectrum from the carrier companies. While I normally filter it out on my specturm maps, there are a number of companies that have very small leases around state and federal correctional facilities for what I presume are these Managed Access Systems that are interdicting cell phone calls, and determine whether devices are permitted to use be in use or not.
Now I have no idea whether Verizon, AT&T, or T-Mobile are being paid for these leases - it could be $1, or could be tens of thousands of dollars. I presume that these MAS companies are also selling mini cell tower to the prison to install so they are interdicting all the calls and none make it out to the regular cell phone network.
Or, Carr might hear the coded message that he can kiss his post-chairman sinecure with the ISP industry goodbye if he lets this through.This is an obviously shit idea, so of course it's going to sail through the current FCC regime and be implemented immediately by asshole prison wardens everywhere.
Much of the prison reform that exists in America are sort of "grassroots efforts." Some years ago, imagine my surprise upon receiving a mobile phone call from a person known to have an earliest release date four years in the future.All this spending of money and none of it for prison and prisoner reform. We are a fucked up country.
The 8-device limit was the nail in the coffin. This meant on any day I had zero guarantee I'd be able to connect to it at all. Neighbors working from home will take precedence. Everybody will. And with the coverage being very weak in the area - their phones will be naturally attracted to it first.That's... how nano-cells work. More range than WiFi-calling, but you have to share with other phone company subscribers. Easier than setting up a farm-wide WiFi system, though.
Should be able to plug into your router's ethernet ports, so you don't use wifi bandwidth.
my county jail is right next to the airport, which I'm sure would have a lot of things to say if a jammer went up.When people think of prisons, they tend to think of the sort of movie version of a supermax prison with big empty areas around the facility. The reality is that even many very high security facilities like US Penitentiary Leavenworth have residential and commercial properties within a quarter mile of the units, and some prisons like this one in Huntsville, TX (image courtesy of Google Maps), have homes and business literally across the street.
Do you have a case citation for this? I'm aware of rulings saying you have no expectation of privacy on someone else's computer, but I believe currently prevailing case law is that you DO have an expectation of privacy on your personal internet connection (which of course your ISP jams a number of terms into your contract to get around, but that is neither here nor there).Maybe somewhere that would be a concern but not in the US. By being present on the private property (especially if there was any barrier to entry such as a basic fence) would be sufficient to negate any expectation to privacy. If you walked into someone's home and started yelling secrets, you would likewise not be granted any privacy protection. Your cellphone is essentially doing just that but in RF instead of audio waves.
Disclaimer, I am not a lawyer, don't take this as legal advice.
Far as I am aware there is no law for a right to privacy of your cellular transmissions. The only reason it's not legal for any random Joe to walk down the street collecting cellphone data as they go is because the spectrum is licensed, so it's unlawful use of the spectrum.
If for instance you do the same thing in the unlicensed wifi spectrum, no problem. In many ways we already do this everyday when we leave our house with wifi enabled in our cellphone and it's updating ssids in the background everywhere we go. Many devices even have the option to auto connect to open networks. And phone oses will monitor ssids and use those to build up location maps to augment GPS positioning info.
If you are in the US and think you have a general right to privacy in your wireless transmissions beyond the bounds of your own private property you are mistaken, unfortunately.
I assume that’s roughly how the MAS systems mentioned in the article work, except those are from third parties, not the carriers, and they apparently allow logging of (and perhaps tracking) of non-white-listed devices. It would seem simpler and cheaper to just do as you suggest, but that cuts out the private third parties, and in modern American prisons, allowing lots of private companies to get their beaks wet seems very important.Is technology available that would consist of a cellular base station programmed with 'whitelist' IMEI numbers that would only accept calls to/from cell phones with those numbers? A station could be installed to cover the prison premises.
It's my understanding that cell phones interface with the strongest base station. If the station were capable of engaging any cell phone but only completing calls with whitelisted IMEIs, this would 'capture' non-whitelisted #s without jamming. Boundary cases would be resolved by users who are free to move away from the prison base station, which prisoners can't do.
Prison staff (guards, etc.) who need communications can use encrypted walkie-talkies, not cell phones. If they need off-site connectivity, they can retrieve their phones from a depository and go far enough away from the prison to be in routine coverage.
Doubtless this isn't a perfect idea, but it would cut down on illegal use without jamming.
edit - autocorrect fail
So, I have no background in cases, and since this is rather new territory I suspect the cases haven't happened yet. Got interested in the technical side after a local school district deployed a private LTE network to allow students to do homework anywhere in the city. That deployment went the route of using CBRS spectrum so it's not interfering with the commercial networks.Do you have a case citation for this? I'm aware of rulings saying you have no expectation of privacy on someone else's computer, but I believe currently prevailing case law is that you DO have an expectation of privacy on your personal internet connection (which of course your ISP jams a number of terms into your contract to get around, but that is neither here nor there).
There's an old case whose name I cannot recall, around the expectation of privacy in public in the US, specifically regarding photographs. Some of the reasoning in that case was that since cameras could be purchased relatively cheaply from the Sears and/or Montgomery Wards catalog, it was unreasonable to expect privacy and to not be photographed in public anymore. (Basically the technology had become ubiquitous enough that it was unreasonable to expect it to not be used. I dont think the same could be argued for cellular interception, since the government, to the best of my knowledge, doesn't let L3Harris sell Stingrays to just anyone)
I realize the current FCC chair is quite ok with what would previously have been considered unacceptable, but I'm VERY surprised that a non-government institution could intercept and DENY access to cell service, given that you could have your phone, NOT agree to interception, and then be blocked from calling 911, which generally the government frowns upon.
The Tercore paper you shared mentioned a deployment at a prison in Puerto Rico, and I have no idea how PR may handle their cell spectrum. I'd be less surprised to see it in a prison, than a private place of business. You'd have to do stuff like put in the contract for the cleaning people that come in the building at night, that they have to accept the interception, or you'd deny them the ability to dial 911 etc.
Also, I would think if this were easy and ubiquitous, places like the Pentagon or the NSA would have this deployed from their perimeter fences inwards and I dont believe that's the case.
A mass murderer's wet dream.IMO cell service jamming should be allowed in more places where people can't control themselves. High schools for example, also movie theaters and concert venues off the top of my head. Also, jamming is something that can be turned on and off as needed.
So the cost of prison calls would go up even further?Following up on this after some additional thought.
1) This white paper is by a company doing MAS solutions for prisons. It provides additional detail for those interested. Including the fact that it can get the device to provide location information that can be used to locate contraband devices for intervention.
2) The better idea would be to have new rules that require these prison telecoms engaged in massive price gouging to pay for installation and maintenance of the MAS at the facility in order to get the concession monopoly. Seems completely reasonable as this would safeguard their own interest in being the monopoly communications provider. This way even small, publicly funded facilities would be able to get a MAS deployed and squeeze contraband cellphones to a trickle.
For bullies, "legal" unrestrained cruelty is why they want to work in prisons. I have some distant (fortunately) family members who worked in prisons, and they were all bullies. What a surprise.All this spending of money and none of it for prison and prisoner reform. We are a fucked up country.
They're subject to the same federal spectrum laws and regulations as the rest of the United states, territory or no.The Tercore paper you shared mentioned a deployment at a prison in Puerto Rico, and I have no idea how PR may handle their cell spectrum.
How stunning someone with your post history is in favor of normalizing government control over who can communicate at all, let alone what they can say.IMO cell service jamming should be allowed in more places where people can't control themselves.
According to this site, they are amazingly expensive.They already have devices called Stingrays that spoof cell phones to see it as a local cell. But stingrays are very expensive. Small local jails may not be able to afford it. Also, stingrays would also intercept calls from neighbors and travelers on the nearby highway.
Aka "Human suffering shameless exploiters like jamming".Prison phone companies like jamming
Unless you attach the jammer directly to the cell phone, it would need to put out a stronger signal than the cell phone does to cause any terminal interference. Hence, your "short range" interference idea badly violates what is even theoretically physically possible.I wonder if a jamming device could be made that has an effective radius of only 1 or 2 meters and wearable.Would it then be possible to attach said device to each inmate, same as they do with house arrest ankle devices? Effectively each inmate would then be a walking sphere of eletromagnetic deadzone. The communication equivalent of a ball and chain.
If the theaters really cared about this they could make their buildings RF-opaque during construction. I've been in theaters that, thanks to being inside steel-reinforced buildings partly below grade level, had no cell signal inside at all.If that is allowed them we need to allow movie theaters to jam cell phone. Yeah I know everyone here will be screaming bloody murder but it's now the primary reason why I don't see movies anymore. I've given up unless I go to a chain (Alamo Drafthouse) who actively will kick people out who use their phone or talk. Which means $20 a ticket vs the $13.
In this case, that's not too problematic - or it wouldn't be if these things were only found in the specialized units that handle cases where standard, boring but effective police work can't get the job done. Cooperative sharing agreements among regional departments would likely fill in any gaps.According to this site, they are amazingly expensive.

These devices are likely made in America.
Probably cheaper from China.

I've used this device for about 9 years now and have actually had no problems. Its range is roughly my house plus about 20 feet outdoors. I doubt it would even register within my next-door-neighbor's walls, and certainly not enough neighbors to exclude my use.The 8-device limit was the nail in the coffin. This meant on any day I had zero guarantee I'd be able to connect to it at all. Neighbors working from home will take precedence. Everybody will. And with the coverage being very weak in the area - their phones will be naturally attracted to it first.
Perhaps because I expect folks here to understand how wireless systems work I am not explaining this sufficiently well, let me try to clarify:I am not a lawyer either, but I'm pretty sure this is completely untrue.
18 U.S. Code § 2511 (Interception and disclosure of wire, oral, or electronic communications prohibited) is the U.S. federal law that prohibits interception of electronic communications.
There are a whole bunch of exceptions. The authorities can get warrants. Telcos and ISPs can do various things necessary to the operation of their networks. It's not a federal crime to listen to a radio station. Some of those exceptions may be over-broad, and are probably being abused. But, the existence of "search warrants", or "exigent circumstances" (say, your house is on fire), and even things like the rampant over-use of "no-knock warrants" or FISA, does not mean that you have no right to control access to your own home, and that anyone can just waltz into your home with total impunity. In the United States it is, generally speaking, a federal crime to intercept other people's cell-phone calls.
It shall not be unlawful under this chapter for an operator of a switchboard, or an officer, employee, or agent of a provider of wire or electronic communication service, whose facilities are used in the transmission of a wire or electronic communication, to intercept, disclose, or use that communication in the normal course of his employment while engaged in any activity which is a necessary incident to the rendition of his service or to the protection of the rights or property of the provider of that service, except that a provider of wire communication service to the public shall not utilize service observing or random monitoring except for mechanical or service quality control checks.
While the idea of placing cell jammers in public locations is certainly problematic, I don't think the intent of jamming entertainment venues is government control. No need to be condescending.How stunning someone with your post history is in favor of normalizing government control over who can communicate at all, let alone what they can say.
Dude, the White House is so many orders of magnitude beyond your plan it's just silly.Step 1 jam cell phones at prisons.
Step 2 redefine what a prison is and how far away you want to jam
Step 3 ....
Step 4 Coup!
We are social animals and punishment for social transgressions is genetically bundled in.A much better idea is prison abolition. Treating prisoners like they're humans, and like the sentence they're serving is that they're stuck in a place. Not so much the constant barbaric dehumanization.
Why is suggesting public schools are entertainment venues not now also worthy of a sideways look?While the idea of placing cell jammers in public locations is certainly problematic, I don't think the intent of jamming entertainment venues is government control. No need to be condescending.
The US prison system is big business.Aka "Human suffering shameless exploiters like jamming".
We don't have prison phone companies in Europe, nor private prison companies.
Are both US-only novelties?
Genetically bundled in? 'Reprisal' would better fit that level of evolutionary hard-wiring.We are social animals and punishment for social transgressions is genetically bundled in.
Agreed.Sure, treat people decently. Including those that commit crimes.
Detecting a bit of sarcasm here. I think the OP meant something along the lines of an ankle bracelet, and if so I agree that would be a far better solution than incarceration inside America's prison system, especially if you'd prefer that ex-cons really do have a healthier outlook toward society and their own future upon release.But without prison, how are you going to punish serious crimes (e.g. murder) ? Death penalty ? Ostracism to a remote desert island ? A kiss on the cheek ?
