Cell Phone Jammer work by sending out an RF or Radio Frequency signal that is more powerful than the power from the nearest Cell Phone Base Station (Cell Phone Tower), the frequency of this RF signal is similar to that used by the cellular carriers and makes the phone un-usable (The Downlink Frequency is the signal that is jammed, not the Uplink frequency from the Cell Phone). When a cell phone jammer is in use you will not see any bars of signal on your phone. Mobile phone jammers will not only block the signal, but because the cellular jammer has overcome all of the cellular frequency, you will not even be able to make a 911 call. This is one of the reasons along with many others that cell phone jammers are so dangerous, and illegal. The use of a mobile phone jammer should not be taken lightly, not only are you breaking the law, but because you have completely blocked the entire spectrum by using the cell phone jammer you may be creating a potentially dangerous situation if the use of a cell phone is needed urgently.

Jammers are illegal in the United States for a myriad of other reasons. First, there’s the concern that jammers could be used by criminals to block 911 or police calls during a crime. In fact, jamming devices were originally created by the military to interrupt communications from terrorists, according to howstuffworks.com.

In addition to these security issues, jammers are also illegal, because according to the Communications Act of 1934, "interference with a phone is considered a property theft". For each call, an individual basically deals with a private company (its operator). These operators have purchased "radio spectrum rights" to process these transactions. When jammers interrupt the phone, they are "stealing" property purchased by these companies.

However, some specific areas and times can legally use jammers, such as classrooms in the test area and prisons for prisoners.
