You Can't Jam The Terrorist's Phones Without Jamming Everybody Else's
from the all-or-nothing dept
Police officials in New York City are investigating how to jam terrorists' cell phones during attacks, following the Mumbai attacks a few months ago when terrorists coordinated their activities via phone. While disrupting criminals' and terrorists' communications could be a useful tool in security forces' arsenal, it's also worth mentioning that technologies like phone jammers can't really work selectively; that is, they can't pick out particular devices, they simply jam everything in a particular area. While this would crudely accomplish the goal of jamming terrorists' phone calls, it would also preclude any other calls, including those of civilians and authorities. Fortunately, this concept isn't lost on NYC police, who say that not blocking calls, and being able to monitor them instead, could be more useful. But even then, it's not clear how authorities could pinpoint terrorists' phones to monitor their conversations without trolling through all the calls being made in an area. At this point, blocking all cell calls during a terrorist attack or large-scale emergency seems like overkill that could be more harmful than helpful.

So let me get this straight, there's only one terrorist. But he has a bitchload of phones?

I for one am shocked
Say it ain't so...authorities saying it's just "simpler" to listen in.

When you have no idea about subject
The reason is that police (and 3-letter agencies) uses for communication other parts of spectrum and protocols designed to work in such conditions (EWF in effect).
Most recent example:
During assault on Gaza, IDF successfully jammed all communications without affecting ability of forces to talk each to other.

Of course it's possible
very little time and old cheap equipment. Geez, and I'm not even a techie. That's what the mercinary military freaks in San Diego run on civilians when they have nothing better to do, which is fairly often.

I do think that if NYC jammed cell phones during a terrorist attack, that it would be a poor idea and only punish the innocent. If the terrorists know that the network is likely to be jammed, they'll find another way to communicate.
So this really leaves the innocent to be punished.

Yosi spat:
Of course! And the crims and terrorists aren't going to use those special police bands because doing so would be breaking the law, right?

Re: Re: When you have no idea about subject
You can't just take you 900Mhz cell phone and adjust it's carrier frequency. You can't replace GSM with custom-designed protocol stack. Not that simple.
You can't take off-the-shelf phone and add EWF-resistant technology there. It doesn't work this way.

Re:
They are not. And usually they don't have on-the-field engineer to diagnose the problem and tweak equipment right way.
EWF is viable and proven. Been used and _will_ be used.

Back to the Future!
So, how many cell towers across all networks, do you suppose are in a highly populated city like NYC?
When working with wireless, and you start jamming a frequency, the network will try to find another timeslot, frequency or a closer basestation based on error-control. Jamming is unrealistic. The chances of one timeslot or one CDMA packet getting back to the network is very high. If NYC wants to pursue this, it's easier to just ask the cellco to turn off the network. (LOL!)
Your exercise in Military theater may have worked, but there's too many recievers that need to be blocked in the likes of NYC. The jammer would probably have to be 1.21 gigawatts, and need a nuclear reaction to generate the electricity.
You ruined my Spacejam movie.

Re: Re:
engineering back up that would make a fortune 500 company envious. Yes they do have in-the-field engineers and they are often former special forces from industrial countries working as mercs. Met then, saw that.
They just don't buy the equipment, they "get it" from military and defense contractor sources and/or they build it.
Terrorists, they're not just for breakfast anymore.
Get with the program, or perish.

Yosi sputtered:
Yeah, of course you can't get stuff that's only available to Law Enforcement. Just like you can't get hold of guns, or bombs, or radioactive materials, or anthrax cultures, or toxic chemicals, or any of the other stuff that the criminals and terrorists aren't supposed to have.

But - dreams and reality never meet. They still have lousy radios, crappy explosives, home-made rockets and failing detonators; while "good guys" have air-force, satellite backed intelligence and hi-tech communications.

Re: Re: Re: When you have no idea about subject
The reasons why "cheap, crappy, lousy" equipment tends to be used in these kinds of attacks are because they work, they're easy to get hold of legally and are hard to trace. If they got hold of the state-of-the-art equipment, they'd be more visible before the attack.
But if you force their hand by, for example, blocking everything but police devices in certain circumstances, they'll find a way to obtain them. Then, you're back to square one - if the police and terrorists have same equipment, you can't block one without blocking the other and they're hard to trace individually.
Meanwhile, you've sacrificed yet another of your freedoms for temporary feelings of security - you've just handed the police the right to block any civilian communications in the name of stopping "terrorism". You might find that power getting abused every so often...

Re:
I think you missed the point. The question isn't whether they can block cellphones - of course they can. The question is whether it's possible to block phones being used by criminals or in a particular area, without taking out every phone within a large radius of the intended target.

grasping at straws

Where does that leave the average citizen? Without cell phone use of course.
Don't you people read the papers? Of course during a disaster they just let the regular system fail (they don't need to block it, call volume just takes it down) while emergency communications go through.
Can the system be hacked? Sure. Is it immune from terrorists? No, but it is what you can do. Just because a system isn't perfect doesn't mean that you don't do it.
People exercise and watch what they eat, doesn't guarantee that they will live longer but it still makes sense to do it.

And YES, they can get time on sats. Yes. Digest that reality for a while. It's done via cell phone code and emergency band frequencies and access to terminals/pedestals in the civilian sector. Have seen it done more than once. Have known some of the freaks because they like to brag in the
watering holes where they join up and because they also demonstrate what they can do because they are a-holes.
I consider them domestic terrorists but the govt considers them guys just keeping ready to be hired to do the black ops/illegal/dirty jobs the govt hires them for.

that is the priority and the only priority at that point in time.
Homeland security and all within them (cops, fire, etc) are on
a different Gig band communications channel than the civilian/consumer sector. They have different equipment and different safeguards. They also have different transponders which would likely reveal terrorists' locations due to the small relative number of them compared with the civilian sector. There are also smaller covert/higher classified groups within Homeland Security to function on different bands than the rest of the organization if their main system goes down or needs to be quieted for a while. The US govt has it all, except wisdom for how to go about dealing with domestic terrorism. They're too busy doing it themselves and calling it the Patriot Act to learn anything which would actually help the civilians. It's now all about protecting the govt. If you are a govt employee you're safe, and if you're a civilian, you're toast no matter what happens. That's the way it is.

Oh, and you get cell service buried under rubble? Hell, by that time, everyone and their brother will be yakking away on the phones and the cell towers will go down naturally anyway.

Article on Wired.com stating how terrorists are using unsecured wireless net connections to plot and carry out their work. So, cell phone jamming wouldn't do much in light of the fact that - surprise! - terrorists also know how to use the Internet.

SOME OF THE WORST CASES OF RACIAL PREJUDICE IN WORLD HISTORY!
The American people are thrilled to have their first African-American president!
Speaking of Barack Obama—Barack Obama is a racial-minority individual and does not like racism:
And Michelle Obama is a racial-minority individual and does not like racism:
WORLDWIDE DISSEMINATION OF INFORMATION RELATING TO SCANDALS:
(I) I do solemnly swear by Almighty God that George W. Bush committed atrocious, racist, hate crimes of epic proportions and with the stench of terrorism which I am not at liberty to mention. Many people know what Bush did. And many people will know what Bush did—even until the end of the world. Bush was absolute evil. Bush is now like a fugitive from justice. Bush is a psychological prisoner. Bush often worries. In any case, Bush will go down in history in infamy.
(II) It is opined that Bill Clinton committed terrifying, racist, hate crimes during his presidency, and I am not free to say anything further about it. ‘Be sure your sins will find you out’ (Numbers 32:23).
(III) What if basically all racial-minority people would subscribe to the interpretations that George Herbert Walker Bush committed monstrous, racist, hate crimes while he was the President of the United States? It will eventually come out: it is only a matter of time.
(IV) I know it may be hard to believe. However, Ronald Wilson Reagan committed horrible, racist, hate crimes during his presidency.

(There are thousands of copies on the Internet indicating the contents of (I), (II), (III), and (IV). For example, one can go to Google right now, type “George W. Bush committed hate crimes of epic proportions and with the stench of terrorism,” hit “Enter,” and readily find 1,000 or more copies indicating content of (I). For example, one can go to Msn right now (13 April 2009), type “It is opined that Bill Clinton committed racist hate crimes, and I am not free to say anything further about it,” hit “Enter,” and readily find more than 460 copies indicating content of (II). For example, one can go to Msn right now, type “George Herbert Walker Bush committed monstrous, racist, hate crimes,” hit “Enter,” and readily find more than 200 copies indicating content of (III). For example, one can go to Msn right now, type “Ronald Wilson Reagan committed horrible, racist, hate crimes during his presidency,” hit “Enter,” and readily find more than 170 copies indicating content of (IV). The contents of (I), (II), (III), and (IV) exist extensively in all major search engines. And there are thousands of copies in very many countries around the world. For example, there are countless copies on the Internet in Australia, Brazil, Canada, China, Denmark, France, Germany, India, Japan, Korea, Russia, the United Kingdom, etc.)
