Disruptor Phone Reception Jammer

What's the difference between jamming cell phone signals and interrupting other signals. Disrupting a cell phone is the same as jamming any other type of radio communication. A cell phone works by communicating with its service network through a cell tower or base station. Cell towers divide a city into small areas, or cells. As a cell-phone user drives down the street, the signal is handed from tower to tower. Actually, the technology behind cell phone signal jamming device is very simple. The jamming broadcasts an RF signal in the frequency range reserved for cell phones that interferes with the cell phone signal, which results in a "no network available" or “weak signal” display on the cell phone screen. The result is that all mobile phones within the effective radius range of the jammer are silenced. In fact, jamming devices block the reception of cell phone signals and are difficult to detect.

While the use of cell phone jammers by private citizens and local businesses remains controversial, a global consensus is forming around the wisdom of jamming cell phones in prisons. All of this would be solved with prison cell phone jammers. There is no reason to not jam prison grounds - guards have walkie talkies that are not affected by jammers (and they shouldn't even have phones on them anyway) so communications would not be interrupted. Jammed airspace can be engineered and tuned as to not effect areas outside the prison. Jammers can be turned off as part of protocol if an emergency is declared and outside emergency agencies need access to the prison. Prison cell phone jammer aims at interrupting communication of unauthorized cell phones in the prison. This device helps in controlling communication of criminals present in the prison. This form of jamming is prevalent in courtroom environment and during military installation. The mechanism of this kind of jamming systems is sophisticated than that of regular cell phone jammers, since it helps to detect the callers automatically or manually and block unauthorized phone calls.
