maybe you need a fish table jammer

As we work with global clients, law enforcement, and military, we ask that all potential clients do their own research for their region, and make an informed decision prior to ordering and use. Many countries have banned the use of not only phone jammers but all types of cell phone jammer. It should be noted that signal detectors are passive and have no restrictions whatsoever.Phone jammers were originally developed by military and law enforcement to help in disrupting adversaries’ communications. These signal jammers can also prevent cell phone bombs detonation. These devices can also help in hostage situations and prevent criminals from speaking with one another.  The law enforcement and military applications are numerous, and life saving.

Many countries have slowly begun legalizing cell phone jammers now that advanced technologies allow emergency communications to function while other communications are disrupted. Most phone jammers can now disrupt regular cell phone signals without disrupting the frequencies used for law enforcement and first responders.Since 2004, France has allowed phone jammers in venues where silence is enforced. French citizens can now use Fish Table Jammer in movie theaters and other performance venues.India has used jammers in both political venues and prisons. Even universities in Italy have used jammers to help prevent students from cheating. 

Trends show that signal jammers will slowly become legalized in many more jurisdictions as the technology advances.Signal boosters and cell signal amplifiers can only boost signals that exist. If you are using a phone jammer to block cellular signals, then a signal booster will not function. Therefore, signal boosters will not cancel out any efforts by a phone jammer.As is explored in the next section, however, there are instances where a phone jammer is rendered ineffective. If the cell phone in question is receiving a strong signal due to a signal booster, it’s possible that your phone jammer won’t have a strong enough output power to cancel out the signal. Or, your device could be set up too far away.
