Title: Signal Jammer
Post by: SuperFlyer on January 18, 2018, 03:32:11 AM
Hi guys,
Where could one buy a powerful jammer that blocks cellphones from speaking and data in a rather large room.
I was looking around but it seems that only shady sites sell them.
I understand that it might be illegal some places, but it's not for use in the USA.
Thank you very much.

I don't know where you plan on using it, but whatever you do don't ship it to the US. It's illegal and they actually do hunt people down for this

There are plenty of other shuls.

Just saying that halachically certain parts of the tfilla if holding even a chumash in the hand means you are not yotse... Much more so by a cellphone.

I don't believe so.

If you wont come to shul because you can't use your phone IMHO you shouldn't be there to begin with. See here (http://forums.dansdeals.com/index.php?topic=32453.msg1834770#msg1834770)

Correct. Even feeling the the phone vibrate is a problem.

Probably not. Some of it will probably involve the Rov hounding repeat offenders.

Just want to point out that blocking signals doesn't mean they won't be able to use their phones at all. It'll eliminate the noise perhaps, and some people don't do much on their phones that doesn't involve internet connectivity - but it's not a full solution. The only full solution is not to have it in shul at all.

There's a guy I see in shul every so often that davens shmona esrai in a minute or two, and then sits down and plays some sort of candy crush type of game. And this wasn't a one time occurrence.

I would actually like to see this happen, and a case go for a legal challenge. I think shuls (and lehavdil theaters etc.) should get an exemption and allow blocking of cell phone signals.

thats why hatzola reccomends every shul have a highly visible " red phone" direct line..... those are probably faster than a cell phone if its in the right place because its direct dial & dispatch can immediately see where you are calling from

There is ways to program a raspberry P1 to jam signals for Wi-Fi maybe cell signals as well(I don't know how)

Either way I hope that was a joke about putting it in shul, it would not solve "the issue" but just the symptom.

Let alone potentially setting yourself up for disaster if/when people find out about it.

Whatever, just sayin...

I agree that it doesn't "solve" the "issue" but does address the symptom. That being said, most people do see value in addressing symptoms, or else sales of ibuprofen and acetaminophen would plunge.

No need to keep it secret. On the contrary, have it well publicized.

The only difference is that this "pill" helps ones headach but gives a headach to others..

Also, I believe people that are "so obsessed" with it to the extent of putting a jammer also have an underlying issue just like the ones actually on the phone.

But yes, it will solve your "headach" and it is a open market.

Which part are you not yotza ? Just because itís against Halacha doesnít mean your not yotza. If itís because heís not concentrating then unfortunately even people without cell phones are in that category. Besides that your last comment is simply not true. Durning shmona esrei where your not allowed to hold anything thatís not for tfillah thereís no difference in holding a chumush or a cell. Donít try to fix the world...work on yourself and learn some Halacha.

There is a solution for hatzola calls.  A repeater with the receiving antenna outside the cage and the transmitting antenna inside on the rx  freq and the reverse for the tx freq.

So, nice to stumble across this - I can't speak of my qualifications in this area ;)

A few things to know - WI-FI blocking while grey area at best is quite legal to kinda "control" if you are a business or school that has a reasonable need to do so. Seeing as it is grey area however, one must be careful as it is not a free for all - see article below.

 https://consumerist.com/2015/08/18/company-fined-750k-for-blocking-wifi-hotspots-at-convention-centers/


While WI-FI jamming/blocking can be grey in certain situations - cell phone signal blocking, being a licensed spectrum is very very illegal, and something that they take very seriously.


AFAIK you will not be able to buy any american made good equipment without the appropriate approvals/permits which is not going to happen.


A faraday would be difficult/impossible to actually implement in most cases.


Only way would be to obtain one from overseas - however as others have noted that would be illegal to own and operate.
