Cell phone boosters amplify 5G, 4G, and LTE for any phone with any carrier for home, office, or vehicle. Wilson Amplifiers is the leading provider of cellular signal boosters. If you're a victim of someone jamming your phone signal, we recommend reaching out to law enforcement or filing a complaint with the FCC. Thus, moving away from your current position may just be enough to get some reception. Jamming range is usually no more than 30 square feet. But it does depend on the sophistication of the jammer that’s blocking your signal. If you’re tech-savvy enough to switch the frequency on which your phone operates, you might have some luck working around the jammer. Unless you can physically locate the jammer itself - which usually looks like a walkie-talkie, a cell phone, or a wireless router - and disable it, blocking signal jammers is not your most viable option. However, if you suspect illegal activity of this sort, contact law enforcement or file a complaint with the FCC.

Without highly advanced, military-level technology at hand, it is virtually impossible for the average consumer to definitively detect a cell phone jammer. While apps do exist that claim to detect signal jammers, they are largely unproven, and require a working signal to function. The most common symptom of cell phone signal jammer interference is, you guessed it, dropped service. As it stands, any signal jammer is also a signal booster jammer. 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 an effective defense against cell phone signal jammers. Do Cell Signal Amplifiers Stop Signal Jammers? However, if that signal is blocked by a jammer, the booster will not work. Signal boosters work by amplifying an existing signal. A signal jammer will interfere with your signal booster. Does a Cell Phone Signal Jammer Block a Cell Phone Signal Booster? That’s why, as mentioned above, the Federal Government has banned the sale, promotion, and use of cell phone signal jammers in the US. It also interferes with GPS, WiFi, and probably most problematic of all - police radar. Keep in mind, a mobile signal jammer will not only block voice and text on your phone. Think schools, theaters, vehicles, or an otherwise quiet train ride… pretty much any venue where talking, texting, streaming and the like might be deemed disruptive or even dangerous. Proponents of such technology argue that signal jammer devices are necessary in places where people struggle to follow standard cell phone etiquette rules. In addition to public safety concerns, radio frequencies are legally protected by The Communications Act of 1934, which outlaws interference with authorized radio broadcasts.

It's illegal to sell, advertise, distribute, or operate cell signal jammers in the United States, as well as much of the world.īecause mobile signal jammer devices intentionally interfere with “authorized radio communications”, the FCC believes that any type of radio communication jamming equipment “pose serious risks to critical public safety communications, and can prevent you and others from making 9-1-1 and other emergency calls… (and) also interfere with law enforcement communications.”

As a result, the device will not function. Oftentimes, jamming one frequency can hoax mobile devices into believing no signal exists. Less sophisticated jammers try to block phone signals by jamming only one frequency. This is known as a 'denial-of-service attack.' When in range of the jamming device, mobile devices will not work. They jam signals by transmitting on the same radio frequencies as cell phones. Known as cell jammers, mobile phone jammers, signal blockers, GPS jammers, or text stoppers, a cell phone signal jammer's main objective is to seize cellular connectivity in a specific area. For example, a cell phone jammer blocks communication between a cell tower and a mobile phone.ĭeveloped for use by the military and law enforcement, these devices were originally created to combat threats like cell phone-triggered explosives and hostage situations. A signal jammer is a device that purposefully disrupts the connection between a device and its signal source.
