The development of mobile devices has greatly promoted the coverage and popularization of WiFi network. Nowadays WiFi and Bluetooth frequency bands, which mainly use 2.4GHz frequency range, are very commonly used for most people to get access to the wireless internet.

However, despite their unquestionable usefulness WiFi and Bluetooth frequencies may be used by the government for shady activities (for example, indoor tracking that is spreading with the lightning speed), which might violate the privacy rights you definitely have. In this case, WiFi is actively used to track your location indoors, mostly through the hotspot location triangulation in a way similar to the cell phone tower location triangulation. And Bluetooth is also used for indoor tracking, particularly in Bluetooth beacons tracking technology. As a precaution against the above situations, WiFi/Bluetooth jammers can help to protect your privacy and hide your location indoors.

The next threat you should be aware of is related to the wireless internet usage. It is the fact that the massive flaw discovered in WPA2, the encryption standard that secures all modern WiFi networks, launched the possibility that anyone near you could easily access your information if you use a WiFi network. Both WiFi and Bluetooth are poorly protected against hackers thus your personal or business data is in highly potential danger all the time if there is a wireless access to the internet nearby. Not only information about you can be stolen, also there are far worse things that might happen: law enforcement agencies can connect to your webcam and watch everything through it, or they can simply use hidden cameras and microphones installed in your house, for eavesdropping and snooping on you secretly, getting back streaming data with the help of WiFi and Bluetooth connections. In such cases, you will need a powerful wireless signal jammer, bluetooth jammer or WIFI blocker. All these devices work on 2.4GHz signal so actually you will only need one device – 2.4GHz WiFi jammer.

Furthermore, smart house systems become more and more in demand nowadays. And devices connected to internet which are so-called “Internet of Things” are spreading everywhere. With such state of things all connected housewares thus may become eyes and ears in your own house, serving to expose your privacy to the government. Under this condition, only portable or desktop WiFi jammers from this category will be able to solve the problem in your advance.

In other cases, there are also some drones and UAVs(Unmanned Aerial Vehicles) controlled via 2.4G frequency which might also be used to spy on you, though most part of those robots are operated with the help of remote controls. So as to be absolutely sure that no spy drone will be used for surveillance on your private meetings, business operations or any other events of your life, you need to resort to a remote control jammer as well as a wifi jammer.

Well, for the most Chinese, this Christmas is somewhat a little tough. You will say:”well, I don’t think so, because in this Christmas, many of them came to other counties and bought lots of good, especially luxury goods, they just like nothing but shopaholic! So how dare you say that they do not have a wonderful festival? They seems happier than us, even this is our own festival. It is really strange.”

Well, for those overseas people, it looks that way. However, for those who are in its own country, they confront a big problem―information disclosing! The fact is that many internet user’s private information has been released. Their confidential information was published on the internet which including their real name, account, password and contact information and so on. What’s more, not only one website is being hacked but other famous Chinese websites suffered the same situation. So far, as more than 100 million people’s private information has been leaked out! It is terrible and very dangerous!

This event causes a thought-provoking about the safety of internet. How to protect our own privacy? If produce the release outside information should by whose quote? And who should pay for the loss of the victims…

Well, at the moment the Chinese do not come up a good solution to deal with this event and this is a warning for us, we should be very careful about our private information, especially when we do something on the internet. Or may be just a Wi-Fi jammer can protect your privacy!

The brief introduction of the principle communication of mobile:
The operating principal of cell phone as follows：in a certain frequency range，cell phone and base station are connected by radio wave , through a definite Baud rate and modulation ways to accomplish the transmission of the data and voice.

FAQ:
Why when jammers working the shielding range will be differed from the instruction?

R: The range and site of the jammer are strongly related with the electromagnetic and the distance of the communication base station. Generally speaking 200meters are the best. Manufactures usually tested in general situation, that’s why there will be a little difference.

Is there any radiation of the cell phone jammer ? And is it harmful to human body?

R: Concerning to radiation, any electronic products will have. Every electrical equipment has radiation. Just like our cell phone we used , radiation is hard to avoid because we place cell phone behind our ears. And there is a national standard of cell phone radiation. However, the generated radiation of our cell phone jammer is far below the national standard , and we don’t need to place it behind our ears every day, therefor , there is hardly damage to our body.

With the development of the network technology and as a means of communication the popularization of cell phone makes it the new favourite among middle school student.Over several years, so long as you put a little attention it is easy for you to see that some students speak with fervour and assurance with cell phones. And it is no longer a fresh news that hearing the ringing of cell phone in the class. The severer situation is that students using the Sms Blasts to send out answers instantly, imagine the mischief.Therefore, besides ideologically educating students realize the harm of cheating in examinations we need to completely eradicate from the technology.

The examination room with the cell phone jammer should meet the following characteristics:

1.Easy installation and carry in, when testing the supervisor take it in to the examination room, you can use while you plug in; taking away while the exam is over;

2.Can shield all kinds of cell phone signals, and you can not call and receive and dispatch messages as well as surf the internet. That means you need to shield the following frequence range: CDMA/GSM/DCS/PHS/TD-SCDMA/WCDMA/CDMA2000; the valid shielding distance must come up to 20 meters;

3.Reasonable price, time limit for quality is three or above three years. School uses jammer only when examination, please put it back to storeroom while finish using.

4.For the best heat dissipation and keep the stable of property, you should use the mental shell.

When the first time the title catches your sight you will definitely jump out and question me:”how darer you to say so? I go there just for relaxing and have a nice time, why should I bring a jammer which will affect my feelings? What a bad idea you advise!” Please take your time, and listen to me carefully.

Well, I am really not a stiff or stereotyped one, on the contrary, I am the one with Petty Bourgeoisie Sentiment and like romance as well as enjoy life. Sometimes, I will go to a bar for relaxing and looking for something that is different. But it may be never occur to you that you are monitored by someone! You must feel I am talking something that out of the fact. No, this is not just alarmist talk! It is the truth. Because about the Fourth Amendment privacy violation cases arguing is still on its way. And you only find out that some bars really use the camera or other devices to monitor you. And even the police also use GPS trackers to do the same thing! The essential thing: “The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no warrants shall issue, but upon probable cause, supported by oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized” has already lose its power, and we are no longer free!

You just wondering why the police or other places can attach this device to detect our privacy? It is unfair and illegal! But now, we seems nothing can do but wait. Therefore, before the amendment come into being we need to take some measures, and buy a jammer will be the best choice. The GPS jammers can disable the GPS tracker and the cell phone jammer can block the signals from all mobile phone! It is really a ideal item.

Have you ever seen the movie called Overheard which was a star-studded cast performed by ChingWan Lau, Louis Koo, Daniel Wu, Jingchu Zhang and Alex Fong and so forth. If you have never seen this film, well I have to say:”You are out of fashion, totally!” The movie Overheard its success not only depended on its real cliffhanger but also relied on its most significant feature was to let every audience into a sense of both.

Now, you must suspect my exaggerate words, it is fine, because I will convince you with the most convincing evidence. The starting poster was very attractive and its blooding degree even can match with the Saw, the horror movie. In fact, there was none business of the story of the play, this was just a metaphor, the graphic designer Frank Chan was only want to describe the darkness and cruel in the inner of human nature. No doubt, they got what they wants. The box office of the film broken into 30 million in only three days! And the total box office was over 110 million!

Actually, not you but others come across with the same problem, it seems that no one can be a exceptional! Yeah, this is the fact. With the ever-increasingly development of science and technology, we can utilize more and more instruments to take photos. Camera is not the only one more, now our laptop, notebook PC, Apple and mobile phone even some MP4 or MP5 can take a photo of us easily. It really bring lots of convenience into our life and at the same time this also make some undesirable person an opportunity that can be exploited to his or her advantage!

Portraiture right is our inviolability right, and we must defend it! But it is so difficult for us to do so, and we really do not have much time to accuse someone or others in the court. So if there is any simple and practicable means to deal with this situation. You are very lucky! We have one.
