Cell Phone Jammers. 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. Jammers have also been used curb phone distractions in meeting by disallowing phones calls and messaging. The technology employs the same principle that is used for disrupting radio waves. The jammers come in different sizes with varying 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. 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. 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. The cell phone jammers available are grouped into two categories according to how they block the signals. The first category is the one that block the radio frequency signals between cell phones and the jammers are always small. 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.

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.
