Cell Phone Jammers.

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. In the recent past, the use of jammers have been extended to religious and workplace. The device will prevent your phone from call of receiving of calls, therefore, guaranteeing zero phone distraction in a meeting. 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. 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. 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. A voltage-controlled oscillator, tuning circuit, noise generator, and an RF amplification which perform specific tasks towards blocking mobile signal are the universal components of a cell phone jammer and they are meant to perform specific functions.

The purpose of the voltage-controlled oscillator is to generate radio signals that will be enough to block the existing mobile signal whereas the tuning circuit regulates the frequency at which the jammer broadcasts its signal. 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.
Case Study: My Experience With Tools

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 frequencies are meant to cause interference with the existing mobile frequencies. Cell phone jammers are group into two broad categories depending on the mobile signals targeted. The first category is the one that block the radio frequency signals between cell phones and the jammers are always small. The other group is meant for large and powerful jammers. The jammers operate by blocking the transmission of mobile signal from the satellite to the cell phone tower.

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 uses of cell phone jammers apart from the ones mentioned above.
