A signal jammer is a simple device that simply blocks all radio frequency transmission between cellular phones and cell towers. Also known as cell-to-cell jammers, GPS jammers, or text stoppers, such a device holds the radio signal down in a given geographical area, creating a kind of virtual signal grid that preventing all communication from being able to reach the user.
Signal jammer effectively holds up the cellular radio signal in a given location, creating a form of virtual signal traffic jam that effectively blocks all communication from being received by all mobile devices. There are many different models of these devices that are available in the market today. It is important for one to know the advantages and disadvantages of using these before deciding on what model or type to use.
One of the most important advantages of using this device is the fact that it prevents interference from other electronic devices. A strong signal jammer helps keep the neighboring wireless phones from interrupting the signal. It is even possible for a signal jammer to cut off the frequency once it has been set. A cell phone jammer works by filtering and blocking radio frequencies, it transmits an unwanted signal. In most cases, unwanted signals are stronger than the ones needed for communication. Cell phone jammers also work by changing the frequencies of certain frequencies to avoid interference. Even the most advanced models of cell phone jammers need to use the correct channels to function properly.
Most of the cell phone jammers function by altering the carrier frequency. This type of frequency is used to filter out unwanted signals. This allows the jammer to only use the required frequencies for communication. There are also some advanced models that can even alter the power and phase of the carrier frequency. These frequencies are particularly used in military applications to jam enemy radar systems.
