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.
A wifi jammer is a device used to block wifi acess from other users in a predetirmined area. they are also expensive and quite possibly illegal
how do we protect our cable network from signal jammer
best offers on mobile signal jammer!! you can buy on it spyworld.in
Yes. but what's the point? Better to just stop transmitting.
Quentin Jammer's birth name is Quentin Tremaine Jammer.
When you use an EMS or cell phone jammer a lower power radio signal is broadcast.this signal is capable of cutting off communication between the cell phone and its base tower.
Quentin Jammer is 6'.
father of jammer

The principle of operation of a noise jammers works on the basis of learn and replicate. the jammer is in most cases associated with a frequency scanner system which identifies the operating frequencies in audio or Rf ranges. based on the detected type of transmission, the jammer emits signals which are similar in characteristics to the noted signal, thus the receiver of radio or Radar whichever is to be noise jammed is now looking at two signals , one from the original source and the other from the jammer. this in turm complicated the listening process and JAMMS its ability to discern the true signal from the false one. Another way of jamming is to forget about first listening and then jamming, all that needs to be done is to identify the frequency band which is to be jammed and direct significant amount of power/ noise form the jammer in that band. this will debilitate the reception of all channels operating in the jammed frequency range and prevent the receiver from receiving the intended signal.
