Functions of a Cell Phone Jammer.

A cell phone jammer is always used for blocking mobile signals in a specific area. The jammers were initially left for use by the defense sector for security purposes. In the recent past, the use of jammers have been extended to religious and workplace. The devices has also been used to ensure meeting runs smoothly without phone distraction by disallowing phone calls and messaging. The working principle of jammer is similar to that that is used for disrupting of 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. A good jammer should also be able to interfere with both speaking and listening signals.

Operating a jammer is simple as it only requires an electrical power source and then you switch it on. It has a bulb lights when it is in operation. Majority of the small jammers relies on electrical energy from a battery while large jammers relies on electricity from plug in power sockets. Large jammers usually has an external antenna that is useful for sending and receiving signals. A standard cell phone jammer is always made up of a voltage-controlled oscillator, tuning circuit, noise generator, and an RF amplification which are required to perform specific tasks.

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.
Lessons Learned About Tools

The techniques that a cell phone jammer uses are similar to those of a radio jammer. A cell phone jammer generates radio frequencies which are those of a mobile phone. The function of the radio frequencies generated is to interfere with the existing mobile phone signals. There are two broad categories in which the cell phone jammers can be grouped depending on the working principle. The first category is the one that block the radio frequency signals between cell phones and the jammers are always small. The second category is meant for the jammers that are larger and more powerful. The large jammers usually target the radio frequency signals between the mobile phone tower and the satellite.
Getting To The Point – Gear

Several types of cell phone jammers exist that vary depending on quality and size. Portable, remote control, adjustable, and school cell phone jammers are some of the types of jammers available. The use of cell phone jammers are not restricted to the ones mentioned above since you can also install them in your home if you want privacy.
