What is a signal jammer?
A signal jammer or jamming transmitter is a small, low-powered transmitter that interfers with receivers in an area around the jammer. The radius of the area will depend on the power of the jammer. The jammer signal will be "seen" by the receiver and it won't then be able to "see" the little signal of the remotely located transmitter that it is trying to "look at" before you turn on your jammer. The jammer transmits a signal (without modulation - it's just the carrier wave) that radiates from the jammer pretty much in all directions (for an omni-directional antenna - which is what is usually on them). This small signal reaches all receivers within the area of its effective range and "swamps" the receivers in that area. Understand that the transmitters reaching out to receivers are generally "high power" units (their power varying depending on what they're designed to do). The jammer is low power. But because the signal from the transmitter is (almost always) a long, long way away from the receivers in the jammer's area, the signal from the transmitter is very tiny in that area. The jammer, on the other hand, has a "large" signal in that area because it's so close to those receivers. It's the amount of signal that gets to a receiver that is important. If a tiny transmitter (a jammer) is "right on top" of a receiver, it will "hit" that receiver hard compared to the tiny signal getting to that receiver from the (high powered) transmitter many miles away. The general rule for power for a transmitter getting to a receiver is that the signal strength is going to be the inverse sqare of the distance from that transmitter. That means that if you have "x" amount of signal at a given spot from a transmitter and them double your distance from the transmitter, the signal will be 1/d2 or 1/22 or 1/4th the amount you had before. Double the distance again and you're down to 1/16th the original amount of signal. A little transmitter works well to jam a receiver if it's right on top of it. It will "blind" the receiver to the "real" signal from the transmitter it is trying to capture. Jammers are generally a no-no, both ethically and legally. Use your head here and think through your options if you are planning some "experimental" electronics. It is the FCC (the Feds) that get down on individuals who interfere with communications. They play hard ball. Imagine interrupting air-to-ground communications and interfering with air traffic. They'd lock you up and throw away the key. Seriously.
Woh kon se device hay jisy lagany say mobile phone jam ho jata hay?
Mobile Jammer
What are the uses of a cell phone jammer?
Cell phones jammers are used to cut off a signal communication between a mobile device and a base station. In an accepted situation, they would be used in an area where silence, respect, or public courtesy is expected.
What's the difference between a Radar Detector and a Radar Jammer?
A radar detector can passively indicate the presence of speed detecting equipment. A radar jammer actively disrupts speed detecting equipment.
Can a jammer be added to video signal during transmission?
Yes. but what's the point? Better to just stop transmitting.
What is the difference between a radar detector and a radar jammer?
A detector alerts the user to the presence of signals used by police equipment. A jammer either blocks or provides false readings on speed detecting equipment.
Can a thick metal casing or box work as Phone Jammer for mobile phone or GPS?
Yes but depends on what type of metal.
Can it disturb recording on the mobile phone?
Only WD-88II recording jammer can make it. Other brands of jammer can only disturb video tape recorder. It is the most advanced one among all products we've purchased.
In cyber bullying are mobile phones dangerous?
Of course mobile phones are dangerous when it comes to cyber bulling. The best way to stop mobile phone bullying is to use mobile phone jammer http://www.espow.com/wholesale-security-surveillance-jammer.html
What is the birth name of Quentin Jammer?
Quentin Jammer's birth name is Quentin Tremaine Jammer.
Is jammer a word?
Yes, "jammer" is a word. It refers to a device that can block or interfere with electronic signals, such as in the case of a GPS jammer or a cellphone jammer.
