April 14th, 2010

When it comes to this question , whether people should use mobile phone jammer or not , different people have different opinions . Some people approve it , while some people are against it . In my opinion , I don’t agree to use cell phone jamming device. Now , I will give you my reasons in the following paragraphs .

Although cell phone blocker provide some convenience for some people , they also affect the normal life . If there are a mobile phone jamming device around you , your phone’s signal will be affected seriously . In fact , many people have the same experience in their life . For example , if you live around one of famous universities , when large examinations are held here ,  cell phone jamming device may be used here in order  to prohibit the signals from outside world to affect the exam’s result , and at the same time in order to avoid the students’ cheating .   But this action is good for examination , it affects the people’s life around . People there usually can’t accept signals from the cell phone for a long time . They can’t have a relationship with their family and friends for a long time . If they are not  any emergent things , it’s ok . But if that’s an important thing for somebody , he must be very worried and feel very terrible .

Just as a saying says :” One coin has two sides “ . Anything has good aspects and also has bad aspects

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.

I believe that everyone has the experience of getting unwanted phone calls. How to get rid of the disturbance of these phone calls? There is a convenient and easy way to get them to stop calling you. A cell phone jammers can stop all these unexpected calls.

When used, the jammer effectively disables cellular phones. There are mainly three types of mobile phone jammers, including handheld mobile phone jammers, desktop mobile phone jammers and wall-mounted mobile phone jammers.

Smaller handheld models block all bands from 800MHz to 1900MHz within a 30-foot range (9 meters). Small devices tend to use the former method, while larger more expensive models may interfere directly with the tower. The radius of cell phone jamming device can range from a dozen feet for pocket models to kilometers for more dedicated units. The TRJ-89 jammer can block cellular communications for a 5-mile (8 km) radius.

Mobile phone jamming device

January 22nd, 2010

According to a recent article in the New York Times, the Federal Communication Commission (FCC) warns that people caught using a mobile phone blocking device could be fined up to $11,000 for a first offense. FCC investigators have special technology of their own that can detect the mobile phone blocking device. The commission has already prosecuted several US companies for distributing the devices nationally.

However, using the cell phone jamming device is illegal in the US, since the radio frequencies used by cell phone carriers are legally protected by the government, similar to the protected frequencies used by television and radio broadcasters. Cell phone companies spend tens of billions of dollars to lease the frequencies from the government, and expect protection from infringement.

But in other situations, private businesses have “no cell phone” policies within limited areas to ensure that their employees´ or clients´ concentration is not interrupted. In these places, people shouldn´t be using cell phones in the first place, and the cell phone jammers simply enforce that policy.

While many people find cell phone blockering device fun as a sort of practical joke, there is also a serious side to the debate. The jammers raise a security threat, since criminals could use them to prevent hostages or others from communicating in an emergency.

cell phone jammers is currently being sold on many online stores. When you choose a cell phone jammers, you must first consider whether the using of cell phone jamming device is legal in your country.

Cell phone jamming device is not new, but it´s becoming increasingly popular on buses, in restaurants, and in movie theaters. The cell phone jamming device works by sending out a powerful radio signal that overwhelms cell phones so that they cannot communicate with cell towers.
