Mobile phones are ubiquitous everywhere these days. Indeed, it brings people more convenience to keep up with your family, friends and business at any time. While every coin has two sides, cell phone is no exception. For example, restaurants, movie theaters, concerts, shopping malls and churches all suffer from the spread of cell phones. It is because not all cell-phone users know when to stop talking. Luckily, a portable mobile phone jammer helps at such occasion. Before using it, you need to learn the basic knowledge of a cell phone jammer.

1. What is a mobile phone jammer?
According to the free encyclopedia-Wikipedia, A mobile phone jammer is an instrument used to prevent cellular phones from receiving signals from or transmitting signals to base stations. That is to say, a cell phone jammer is a device that creates a temporary “dead zone” to all cell phone traffic in their immediate proximity.

When a mobile phone is used, the jammer effectively disables cellular phones. Jammers were typically used by the police and military to control or disrupt communication during hostage situations and bomb threats. Nowadays, these devices can be used in practically any location, but are found primarily in places where a phone call would be particularly disruptive because silence is expected.

Traditionally, jammers were large antennas mounted on trailers that had to be pulled behind a truck. But now jammers come in much smaller sizes, they are very easy to carry around. For example, a portable cell phone jammer can fit into the palm of your hand or easily slip into your coat pocket.

2. How does a mobile phone jammer work?
It is known to all that cell phones are basically handheld two-way radios. And like any radio, the signal can be disrupted, or jammed. As with other radio jamming, cell phone jammers block cell phone use by sending out radio waves along the same frequencies that cellular phones use.

Disrupting a cell phone is the same as jamming any other type of radio communication. A cell phone works by communicating with its service network through a cell tower or base station. A jamming device transmits on the same radio frequencies as the cell phone, disrupting the communication between the phone and the cell-phone base station in the tower.

So the next time someone on your commuter bus refuses to shut up, you can just reach into your backpack and turn on a temporary “dead zone” with your jammer. Then get back to some nice peace and quiet.
