Some Discussion about GPS jammers

GPS jammers are used more and more widely. Why? The reason we have already discussed. It is because today our privacy is very easy to reveal. GPS jammers can prevent someone from tracking your actions to protect your privacy. Interference equipment can now be easily ordered online.

About the law of GPS jammers we should know that it is illegal in the United States and is limited in Europe. However, the laws of some other countries are less clear. Therefore, please confirm the local law before buying.

For the use of GPS jammers, some people say that GPS interference is dangerous to society. "I am worried that China's factories are starting to figure out these things," said Peter Large, vice president of Trimble, Sunnyvale, Calif., Who developed advanced positioning systems. "If they start to proliferate, they may have devastating consequences."

GPS jammers may be used for bad purposes. Criminals, car thieves and mischief can use GPS jammers to eliminate bad behavior. For example, if a car thief steals a car with a GPS jammer, the law enforcement agency will not be able to track the vehicle using GPS tracking equipment. Interference equipment can also be used to block toll roads.

However, some people think that these devices are useful and people should have the right to buy them. For example, GPS jammers can be easily stored in cars or luggage, and can help avoid spy detection - such as from suspected spouse of infidelity, and in the car like Zoombak such GPS tracking device.

We think that GPS jammers can be used improperly, but without it, how do we sometimes deal with some tracking? The gun is more dangerous than the jammers, but many places are legitimate guns. So, the most important thing is its rational application. What do you think?

In order to prevent candidates from using mobile phones and other wireless communication equipment for cheating, government use the cell phone jammers during the contest without interrupting the signals around the test.

It is reported that this year is the second year after "cheating should be put in prison", so the discipline of the examination has become the most important, the opening of the jammers to test the proportion is 100%.

As the main city of Chongqing college entrance examination centers are in the downtown area, a large number of wifi jammers will have a great impact on the normal communication of the surrounding users .

The Opinions of Stopping Cell Phone in some Public Places

These days, it is almost impossible to catch a movie, or eat in the restaurant, and will not let the phone sounded interrupted.

"Sometimes I went to a restaurant where I wanted to enjoy a meal or coffee, read quietly, and someone started talking loudly on their cell phone, which was annoying," said Charles Crowder, a resident of Oakland, California.

The world's more than 100 million mobile phone growth, the problem may be getting worse. In the United States alone, it is estimated that within five years, 84% of US citizens will have mobile phones.

However, the rebound for cell nuisance has already begun. Restaurants in the United States, requiring visitors to turn off the phone logo is more and more common. In Baxter State Park, Maine, in addition to emergency situations, the phone is illegal. Resistance even reached the White House: President Bush reportedly banned mobile phone staff meetings.

In fact, several governments around the world are considering the legalization of cell signal technology, in the public space on the phone to add rituals.

Mobile Phone Jammers have been in existence since 1998. Interference to send low power coded radio signals or modulated radio waves.

The jammers work in one of two ways. Some devices set their signals to the same frequency as pagers and mobile phones, thereby disconnecting traffic between the handset and the base station. Other people as an electronic filter, fool the phone, that no frequency can be used to make or receive calls. Interference only affects the specified area (most of the radius is tens to hundreds of feet) and can only work on cellular transmissions.

Sounds like a perfect solution for the phone? The problem is that in addition to Israel and Japan, most developed countries, including the United States, Britain, Canada, Switzerland and Australia, mobile phone jammers are still illegal.

However, the tide may be changing. In the past spring, both Hong Kong and Canada have announced that they will consider legalizing the means of interference to curb public telephone behavior. At about the same time, the leaders of the Indian parliament revealed that they had installed the WiFi jammers to avoid interruption during the meeting.

However, this major change in the legal outlook is not so far-fetched as the public's dissatisfaction with chirping continues to grow. Last year, Letstalk.com found that 57 percent of Americans favored phone calls from restaurants, theaters and other public places.

Just as parents have the ability to cut Wi-Fi right at home, they should be able to cut off cellular signals if needed. Putting them on the phone with their hands in the airplane mode may not work properly, turn the house into a Faraday cage, it's just a very much only one that should try the tin foil hat. However, if necessary or needed, the indoor cell phone jammer should be an option.

All of these examples are based on other lines that can be used for emergencies, or at least some people want mobility sufficient to exceed the interference range. There is absolutely no way now, even those most meaningful people can use limited technology, will not disrupt the service, far beyond their classroom, theater, office or family range.

But before you finish, think about it, if you really get hurt, or maybe that time, no cell signal is the best moment of your day. Of Course, if your signal stuck, you may not be able to make a call.
