• To anyone looking to acquire commercial radio programming software:

    Please do not make requests for copies of radio programming software which is sold (or was sold) by the manufacturer for any monetary value. All requests will be deleted and a forum infraction issued. Making a request such as this is attempting to engage in software piracy and this forum cannot be involved or associated with this activity. The same goes for any private transaction via Private Message. Even if you attempt to engage in this activity in PM's we will still enforce the forum rules. Your PM's are not private and the administration has the right to read them if there's a hint to criminal activity.

    If you are having trouble legally obtaining software please state so. We do not want any hurt feelings when your vague post is mistaken for a free request. It is YOUR responsibility to properly word your request.

    To obtain Motorola software see the Sticky in the Motorola forum.

    The various other vendors often permit their dealers to sell the software online (i.e., Kenwood). Please use Google or some other search engine to find a dealer that sells the software. Typically each series or individual radio requires its own software package. Often the Kenwood software is less than $100 so don't be a cheapskate; just purchase it.

    For M/A Com/Harris/GE, etc: there are two software packages that program all current and past radios. One package is for conventional programming and the other for trunked programming. The trunked package is in upwards of $2,500. The conventional package is more reasonable though is still several hundred dollars. The benefit is you do not need multiple versions for each radio (unlike Motorola).

    This is a large and very visible forum. We cannot jeopardize the ability to provide the RadioReference services by allowing this activity to occur. Please respect this.

"State AGs urge passage of legislation allowing for cell phone ‘jamming’ systems in prisons"

"(WKBN) – Pennsylvania Attorney General Dave Sunday has joined a bipartisan coalition of 26 state attorneys general calling on Congress to pass legislation allowing states to deploy cell phone “jamming” systems in prisons.

“Jamming” involves the interruption of cell phone signals, which would disable non-emergency calls.

The legislation — H.R. 2350 and S. 1137 — regards contraband phones and would not impact individuals’ usage of landline phones at prisons, according to a news release from the Attorney General’s Office."

There are ways to do this that aren't "jamming", and as stated, still allow emergency calls. I suspect either the AG or the media doesn't know the difference and are just using an easy to recognize term.

But what if an EMS crew uses cellular to call a hospital directly or uses cellular Internet to connect to a hospital?
What if either or both of those are blocked when they respond to a prison?

Something the individual prisons will need to work out with responding agencies. Likely after the fact….

The solution is better control of your staff. Creating intentional interference is a liability, as others have stated, part 90 gets interference, it's life safety of the very staff one may be attempting to assist. Not to mention, if these jamming devices impair the macro networks, then they are not only in violation but could disrupt/impair communications outside the walls of the institutions.

Seems like there may be better technical solutions to what they are aiming at overall.

If finding the people with the cell phones is the key, then maybe something like this behind each cells wall might be helpful to pinpoint where they are.


(I assume there is a cavity behind each cells wall for plumbing, ventilation, electrical runs etc...)

Considering the trouble cell phones and amplified speakers had caused, while TRYING to keep the noise out of them,... it doesn't seem like too much of a stretch to just find the offenders to begin with

Thanks

In simplified terms:

Small cells internal to the prison broadcasting carrier info so phones connect to that system. The system acts as the gateway into the cellular networks with connections to each of carriers. The gateway will block unknown phones.

Prisons usually have their own medical teams, so someone needing emergency medical care would be removed to an on site medical facility. EMS isn't going to be wandering around the inside of a prison with a big box full of drugs.

The gateways can be programmed with info for agency owned cell phones, so they can work from inside if needed. A master kill switch can be set up to temporarily allow all calls if necessary.

But agencies are going to rely on their own radios, not personal cell phones. EMS would be transporting a patient to an outside hospital where such a system wouldn't be a hindrance.

I imagine so.

There are a number of places running neutral carrier systems. Federated Wireless has been doing this for a while. A number of big university campuses are running their own LTE systems on CBRS with gateways back into the cellular carriers. This isn't really that different, just blocking phones that are not allowed to use the system. Easy enough to allow 911 to pass through.

I think a variation of the Stingray Cellular system would be something to look in to. It would allow cellular traffic to pass but can analyze the traffic to determine if it is coming from inside the facility walls. EMS typically isn't permitted inside of the prison. The guards will get the inmate to a medical portion of the prison and turn over patient care at that point. There a million variables to the scenario. What did EMS do 40+ years ago BEFORE cellphones? Build the new prisons as giant faraday cages!

I think a prison near me has this. The prison is next to a busy highway interchange, and every time I drive by my phone stops working despite having full signal (in this spot, there is literally line of site to a cell phone tower less than a mile away). I have no idea how it's been allowed to continue in such a busy area for so long. I imagine that most people just haven't figured out that such a system exists and have not thought to complain to the cell company and/or prison about it. To them, it's just another dead spot in the cell network.

I think the key is going to be having the "kill-switch" with reliable remote control be part of the protocol for a mass-casualty or other type of event that would require unregistered phones to be able to work. Doesn't do much good to chase down and imprison the guys at the top if they can just continue to easily run things from inside.

Thats why I was suggesting to go and actually get the phones themselves. I don't know how difficult it would be, but even with cell service not available, there are lots of things that can be done with a phone (stored movies, video games, etc...).

Thanks

If I'm not mistaken, El Salvador uses cell jammers in their prisons. And with good reason, too! Other central American countries may do the same.

In my opinion, something like this SHOULD be done, but in an effective manner that doesn't disrupt the civilian use of cell phones. I'm not sure if juvenile facilities need call jammers though. I realize some of these kids are gang members though...

So as a paramedic who works in an area with several prisons, I can say that EMS can and does wander around inside the prison and cell blocks with all our equipment, though we are never without an escort. EMS making phone calls from the patient is a non issue, because we're not allowed to take our phones out of the ambulance, and no guards or visitors are allowed to have cell phones, so the only people that would have them are people that aren't supposed to have them.
