It is advanced in the respect that it is narrow enough of interference to only interfere with cell phone (or other items on the narrow frequencies)... this is of course assuming that the jammer is able to narrow it's field of interference.

Spark-gap devices are very noisy as well, and practically impossible to operate in 'stealth' mode.

      Now, with all that said, and to answer your original question: A jamming device, being (in most cases) a simple transmitter or sweep oscillator, can be made as narrow or as broad-banded as available funds or circumstances dictate.

This way a government agency knows what frequencies are most likely to be used, and therefore easier to be jammed. Of course it is possible to make a bomb detonate on other frequencies too, but are the average terrorist capable of that?

      If it is a stationary target the thing got a whole lot easier for the terrorist. But the timer still must be pretty precise, when security guards nowadays are on constant lookout for bombs. You would need to make sure that you have time to plant the bomb and get out. The bomb is most likely found in a couple of minutes if it is in a busy train station or so.

They used box-cutters. I'm fairly certain that whatever choice they make next is going to be a surprise. It's not going to be something that the US Gov't expects, so let's stop trying to list the millions of possible ways and monitor the thousands of possible targets.

I mean, come on Monica, that's something a 7th grader would say. There's a balance between cost and safety, and nobody in her right mind would suggest spending an unlimited amount of public funds just to make sure we can catch someone who has a box-cutter, because there's a one in a billion chance he might want to also fly an airliner into a building.

    Likewise we have El Rushbo, trumpeting that the fact we haven't had an Al Qaeda attack on US soil for one and a half years is proof positive that Bush's strategy is working. As much as I'd like to believe that, the fact is that it costs Al Qaeda money and takes lots of time to plan an act on US soil. The second WTC attack happened almost 8 years after the first. The attacks aren't likely going to stop as long as we're involved in the Mid-East (as long as we back Israel and pull the strings for the Saudi monarchy).

    So once again, it's not a choice with absolutes. Either we continue our current policy and some of us get killed every ten years or so, or we trade some other lives for our own, and watch the slaughter of the Jews, the Kurds, or some other religious minority that is sufficiently westernized to perhaps believe in freedom, interest on money, rights for women, or perhaps not stoning people to death for breaking society's rules. Or, we pick something inbetween, and successive presidents jump to either side of the fence (like the case now). One thing I can be sure of is that some US citizens are going to have a shot at stopping the next attack, just like the last one. So maybe this time we won't behave like subservient little hoplophobic sheep, and someone will fight back with deadly force to spare the lives of others.

  128. First Responders and Simplicity by Anonymous Coward · · Score: 0
    Many police, fire department, hazmat units and a whole host of people rely on cell-phone communications and to the extent you use jamming devices designed to jam terrorists, you may be jamming the first responders, whose communication is critical in an emergency situation.
    First, this use of cell phone jamming isn't hypothetical. It's exactly what is being done with 'suicide' bombers in Israel. Some of those wired to blow up come to their senses at the last moment. A cell phone is a cheap way to blow them up anyway from a safe distance. It also has one advantage that no other transmitter has. Carrying a cell phone won't attract suspicion. And keep in mind that the jamming is needed BEFORE a blast. Afterward, it can be turned off.

    Second, I work as a volunteer with emergency communications in Seattle. Cell phones are typically worthless near a major emergency. Those who see what has happen call 911. Those near the scene call their spouse to assure them that they're safe. Those driving by call a friend to find out what is happening. And then media descends like locusts with their cell phones already active. As a result all available channels are quickly blocked.

    It would be foolish for a community to depend on cell phones for anything important. In Seattle, even our expensive Motorola 800 MHz trunking system for local government agencies overloaded in our most recent earthquake. And no one could get on that system but various government employees, all of whom seemed to have had the urge to call a buddy to say, "Did you feel that?"

    That's also why for inter-hospital communication, which is where I volunteer, we rely on amateur radio repeaters with backup frequencies and alternate repeaters. And if all else fails, we can run off batteries and talk direct. Each hospital already has one or two amateur radios set up to run off the hospital's emergency power, and I arrive on scene with two more. We drill constantly, so we know what to do.

    In similar fashion, state troopers, who often arrive alone at crime and accident scenes far from metro areas or phone lines, fight being drawn into complex trunking system. They typically use simple VHF repeaters and have high-powered transmitters in their cars, so they can punch through even if the repeater goes down. Their frequencies are just for themselves and they're quite professional at using them. The guys who fix traffic lights or read water meters can't get in the way, much less a twit who wants to use his cell phone to tell his brother-in-law about the big fire he just drove past.

    The No. 1 Rule of Emergency Communication is KISS-Keep It Simple Stupid. The more complex the system, the more likely it is to fail in an emergency. When 9/11 hit NYC, the two major emergency hospitals on the south end of Manhattan could not talk to one another. Most of the phone cables, fiber optics, microwave and cell phone links were under or on the Two Towers that came down. In that sense, it was good the system was not swamped with thousands of injured people.

    There is a scary use for these easily available cell phone jammers. Quite a few people rely on cell phones to call the police when threatened. A brighter-than-usual criminal could jam all cell phone frequencies before attacking.
