The function of a cell phone jammer is to block mobile signals. Some years back the use of cell phone jammers was only left for the security department. Today, jammers have been installed in many areas where usage of phone is not allowed such as religious places and workplace. 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 differentiated based on size and the working radius. The larger the jammer, the larger the working radius range. Some of the jammers are also capable of blocking both listening and speaking 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. Larger jammers are always connected to an output power source while the smaller ones can use batteries such as phone batteries. It usually has an antenna that is useful for sending and receiving signals. 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 jammer is capable of regulating the frequency at which it broadcasts its signal because of the tuning circuit while the voltage-controlled oscillator is meant for production of enough radio signals to block the mobile signals. Noise generator produces random electric output while in a specified range to block mobile signal while the RF amplification enhances the power of radio frequency to levels that can jam a signal.

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 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. 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 category is meant for the jammers that are larger and more powerful. The jammers operate by blocking the transmission of mobile signal from the satellite to the cell phone tower.
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. There are several other places that you can install a cell phone jammer for privacy reasons.
