How Do Cell Phone Signal Jammers Work?

A mobile phone signal jammer, also referred to as a cell jammer, signal blocker, GPS jammer, or text stopper, is a device that disrupts radio frequency signals in a particular area, causing a blockage of all communication. It creates a “silence zone” where calls and texts cannot be transmitted or received while the user is within the range of the jamming device.

Is it Legal to Use Cell Phone Signal Jammers?

If the prospect of a cell phone signal blocker sweeps your imagination off to the secret machinations of an evil Bond villain plotting away in his lair, you’re not alone. That’s why —you guessed it — it is illegal to sell, advertise, distribute, or operate cell signal booster jammers in the United States, as well as much of the world.

Because mobile signal jammer devices intentionally interfere with “authorized radio communications”, the FCC believes that cellular and WiFi signal jammer devices “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.”

In addition to public safety concerns, radio frequencies are legally protected by The Communications Act of 1934, which outlaws interference with authorized radio broadcasts.

So, Why are Cell Phone Signal Jammers Used?

Advocates of cell phone signal jammers argue that these devices are necessary in many locations where people repeatedly violate the rules of proper cell phone etiquette. Examples include schools, theaters, vehicles, and public transportation where talking, texting, and streaming can be disruptive or cause safety hazards.

It’s important to note, however, that a mobile signal jammer not only blocks voice and text communication but also affects GPS, WiFi, and even police radar. For this reason, the US government has prohibited the sale, advertising, and use of cell phone signal jammers. If you were hoping to enjoy a moment of peace and quiet with the help of a signal blocker, you may need to consider using earplugs instead.

Does a Cell Phone Signal Jammer Block a Cell Phone Signal Booster?

Regrettably, a mobile signal jammer can disrupt the functionality of your signal booster. Signal boosters amplify an existing cellular signal, but if that signal is blocked, the strength of the signal becomes irrelevant as the signal jammer will still interfere with it.

What is a Cell Phone Signal Jammer?

Mobile phone signal jammers are designed to disrupt the communication between cell towers and mobile phones by creating interference. Initially developed for military and law enforcement applications, these devices were primarily intended to address potential hazards such as cell phone-triggered explosives and hostage scenarios.

Do Cell Signal Amplifiers Stop Signal Jammers?

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.

How Do I Detect a Signal Jammer?

The primary indication of interference from a cell phone signal jammer is a dropped service, which is the most widespread problem caused by it. Although some apps purport to recognize signal jammers, the efficacy of such applications remains largely unverified, and they require an active signal to function. It is practically impossible for the average user to accurately identify a cell phone jammer unless they possess highly sophisticated military-grade technology.

If there is a suspicion of any illegal activity concerning signal jamming, it is recommended to contact law enforcement or report the issue to the FCC.

What Are the Measures to Prevent Cell Signal Jamming?

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.

If you’re tech savvy enough to switch the frequency on which your phone operates, you might have some luck working around the jammer as well. But it does depend on the sophistication of the jammer that’s blocking your signal.

If you suspect you may be the victim of a cell phone signal jammer attack, your best bet is to relocate. Cell phone signal jammers don’t usually broadcast beyond more than 30 square feet, so moving away from your current position is usually enough to escape the jammer’s range.

Again, contact law enforcement or file a complaint with the FCC if you are being victimized by someone using a cell phone signal blocker.
