How a Cell Phone Jammer Works.

A cell phone jammer is always used for blocking mobile signals in a specific area. Some years back the use of cell phone jammers was only left for the security department. Currently, the use of jammers have been employed in many areas such as phone usage restricted work places and religious places. The devices has also been used to ensure meeting runs smoothly without phone distraction by disallowing phone calls and messaging. The technology employs the same principle that is used for disrupting radio waves. The jammers are available in different sizes and operating range. If you want a large working radius then you should go for a big jammer. Some of the jammers are also capable of blocking both listening and speaking signals.

A jammer operates using electrical power and has a switch button. To determine if it is functioning, the bulb should be on. Majority of the small jammers relies on electrical energy from a battery while large jammers relies on electricity from plug in power sockets. The antenna is used for sending and receiving signal, larger jammers usually have an external jammer. The main electrical components of typical a jammer are voltage-controlled oscillator, tuning circuit, noise generator, and an RF amplification which perform specific tasks towards blocking mobile signal.

The function of the voltage-controlled oscillator is to produce the radio signal that will interfere with the mobile signal while the tuning circuit controls the frequency that the jammer broadcasts its signal. The function of the RF amplification is to boost the power of radio frequency to amounts that can interfere with a signal while the noise generator is for generation of random electrical output to interfere with the existing mobile signals.

A cell phone jammer works the same way as a radio jammer. The radio frequencies produced are always similar to the ones that the mobile phones operate on. The radio frequency generated will interfere with the ones connecting one cell phone to another. There are two broad categories in which the cell phone jammers can be grouped depending on the working principle. One of the categories is the one containing the small jammers that operate by blocking the radio signals between a cell phone and another cell phone. The second group contains the large and powerful jammers. The second category usually operate by causing interference on the radio frequency signals between the satellite and the cell phone towers.

The jammers are always available in different sizes and quality. Portable, remote control, adjustable, and school cell phone jammers are some of the types of jammers available. There are several other places that you can install a cell phone jammer for privacy reasons.
