Silence is golden in certain places. People in libraries, theaters, schools, hospitals, meetings or government offices may benefit from a cell phone jammer. However, using one in a public place can be dangerous.
They can block emergency signals or important police calls. This can leave the jammer liable for any disturbance or legal ramifications that may come. Before choosing, please make sure to review your local regulations before using one. Should you require additional information to help make an informed purchase, please feel free to contact us. Hi I need to built a device by which the user gets the call but they will not be able to talk. He has to switch it off to attend the call.
Hey , Brother cell phone signal jammer is a electronic RF hardware which can cancel the signals which are sent from your cell phone device to the tower ,therefore is capable to deal with radio frequencies RF ,but according to your requirement your device needs a program or application to execute this process.
What is the perimeter range of a cell phone jammer? And does it also inhibit internet usage as well? Thanks for your help! Hi Noelle, it depends on the power output measured in Watts , and to a small degree the local signal strength. Where the signal is stronger, coverage is slightly weaker, and vice versa. So it will depend on what model you are looking at.

The ubiquity of cell phones means there are a lot of unwanted phone calls. Fortunately, cell phone jammers exist. What are Cell Phone Jammers? Once you know the frequency of your target signal, simply overpower that signal by emitting a stronger signal of your own.
The further away it is, the more power you need to drown it out. If the signal jumps frequencies, cast a wider blanket of signal disruption by covering a range of frequencies. When your phone is being jammed, you will not see any signal bars on your phone. Cell phone jammers will not only block the signal, but because the jammer has overpowered all of the cellular frequency, you will not be able to conduct a emergency call.
This is one of the primary reasons that mobile phone jammers are so dangerous, in addition to inhibiting routine communications and the reception of public safety messages or announcements. By using one, a person has created a potentially hazardous situation if someone has an urgent need for mobile communication. For these reasons, cell phone jammers are illegal in many countries. If a person uses one in the United States, they are breaking federal law. Like many countries, the United States prohibits the employment of cell phone jammers in practically every use case.
While cell phone signal amplifiers are an excellent tool for strengthening reception in rural areas , on the road , or when building materials get in the way, they are not yet an effective defense against cell phone signal jammers. As it stands, any signal jammer is also a signal booster jammer. The most common symptom of cell phone signal jammer interference is, you guessed it, dropped service. While apps do exist that claim to detect signal jammers, they are largely unproven, and require a working signal to function.
Without highly advanced, military-level technology at hand, it is virtually impossible for the average consumer to definitively detect a cell phone jammer. However, if you suspect illegal activity of this sort, contact law enforcement or file a complaint with the FCC.
