RF Jammers for purposes

When you are dealing with terrorists and criminals, disrupting their ability communicate turns organized crime into less of a threat. Cell phones have enabled everyone with criminal intentions, from drug dealers to insurgents in Iraq to be able to both communicate, and to use cell phones to set off road side explosives. But are there non-military uses of radio jammers? The answer is yes. Various personal protective services, such as the United States secret service, may use radio jamming techniques to make sure that terrorists are unable to use radio frequencies to set off improvised explosive devices with cell phones.

In hostage situations the police can use RF jammers to cut off communication between hostage takers and the outside world. In addition, some banks in countries other than the United States use them so that criminals can survey the inside of the bank for customers making big withdrawals and then arrange for them to be robbed outside the bank. Various corporations with sensitive industrial secrets might use RF jammers to prevent people from stealing information with cell phones.

While there are a variety of serious fines and jail times a person could receive for using a radio jammer device not in connection with law enforcement or government sanction, the FCC has not prosecuted anyone for this crime yet. There are a number of devices which one can purchase which vary in the range that they are able to block cell phones, which may range from dozens of feet to miles in radius. Jamming cell phone signals is illegal because the cell phone carriers that use those frequencies have purchased exclusive rights to use them for communication.

There are many places in the United States where RF jammers could be sold if legal, and include movies theaters and churches. However, the FCC will likely not change rules about such private use of RF jammers as cell phones also provide a way for people to get in contact with emergency services if needed.

Some companies are also marketing RF jammers for use in prisons. This is because smuggling cell phones into prisons is big business, and more easily accomplished than in decades past as cell phones have become increasingly physically smaller. While some inmates may use a cell phone just to get extra time talking with their family members each month, others have more nefarious motives as crimes can be coordinated from
inside a prison more easily when an inmate has an illegal cell phone. Newer technology may allow prison officials to eavesdrop on inmates unauthorized cell phone calls, and then jam them when their criminal intent is documented.

Besides blocking cell phone signals, RF jamming can also target GPS signals such as those that a GPS positioning device uses, such that it will not function. A private civilian might use such a jammer to avoid having movements being tracked with any secretly placed GPS positioning devices on their person or on their car.
