Signal Jammer Tip: How do Cell Phone Jammers work?
In order to better understand how a Portable Cell Phone Jammer works, it is beneficial to first understand how your cell phone functions.

In short, every cell phone utilizes two different frequencies. One of the frequencies is used to transmit information, while the other is used to receive information. Regardless of the frequency used, the signal must first originate from one phone, and then get sent to the base station. From the base station, it is relayed to the receiving cell phone.

When you use a Portable Cell Phone Jammer, the signals transmitted by the cell phone actually collide with the signals transmitted by the phone jammer. When the two signals collide, they are essentially canceled out, and the link between cellular base station and cellular handset is disconnected - providing the cell phone with no service / no signal. When the cell phone jammer is turned off, the cell phone signal is instantly returned.

As a result, the cell phone user is unable to make or receive phone calls while the cell phone jammer is turned on. Additionally, any calls in progress will be disconnected when the cell phone jammer is turned on.

In order to block out a desired area, it is important to choose the right type of Portable Cell Phone Jammer. Some are able to transmit signals in a far larger area than others. Many of our competitors products, which are actually considered novelty items, only transmit over a 2 meter (6 foot) area - therefore, you need to assess your needs and the amount of coverage desired, so that you can select the cell phone blocker that is right for you.
