In the eyes of many people, the jammer is just a tool to block the signal. There is no other purpose. Do you really understand the jammer? Let me explain briefly for you today.
We all wanted to strangle them before. There is nothing worse than morons on their cell phones while you are trying to enjoy a movie, a meal in a restaurant or a quiet nap on the bus or train to go to work. In fact, listening to only one side of a stupid conversation is paying us more attention than usual. Our brain is waiting for information from both sides of a conversation, and it will try to fill in the blanks. You can try to send the mobile blablablou some bad looks or the old “courtesy cough”, but these passive aggressive gestures rarely work.
If you really want to close a chat box, then you will need to acquire a cell phone jammer.
WHAT IS A “JAMMER”?
Cell phone jammers are devices that create a temporary “dead zone” for all cell phone traffic in their immediate vicinity. Jammers are generally used by police and the military to control or disrupt communication during hostage-taking and bomb threats. Traditionally, jammers were large antennas mounted on trailers that had to be pulled behind a truck. They now come in a variety of shapes and sizes, including models that are roughly the size of a cell phone.
Use a jammer
Because the jammers now come in much smaller sizes, they are very easy to transport. Portable personal jammers slip into the palm of your hand or easily slip into your coat pocket. So the next time someone on your commuter bus refuses to shut up, you can just reach your backpack and light up a temporary “dead zone” with your jammer. Then return to peace and tranquility.
Most jammers have a range of about 50 to 80 feet and will not effectively jam your immediate environment. Mobile blabbermouths will just think they’ve hit a break-even point in their cell phone company coverage until they leave your jamming surroundings. More powerful jammers are available to cover larger structures such as office buildings, cinemas and churches. They look like various metal boxes with wires sticking out and are usually mounted on walls or ceilings (see image on the right).
Most mobile phone jammers exist in two versions, one for Europe, North Africa and GSM networks in the Gulf countries (900 and 1800) and the other for the Americas and Canada networks (800 and 1900 MHz). Make sure you get the right version for your location.
