　　孩子沉迷手机聊天怎么办，半夜没有好好休息，玩手机游戏怎么办？学会自律。但是有些家长反映实际困难，孩子有时也不是那么听话，能花几百块钱买个拦截器，防止孩子沉迷手机吗？

　　希望购买家用手机信号屏蔽器来干扰或切断手机信号，从而防止孩子上网是可以理解的，但是使用手机信号屏蔽器有几点需要注意。

　　首先是干扰器的功率，直接影响屏蔽器的屏蔽距离，适合在不影响周围邻居的情况下屏蔽孩子房间的信号，如果干扰了邻居的信号就麻烦了。

　　二是干扰信号，因为是防止孩子在家玩手机，所以需要能够同时屏蔽WiFi信号和移动网络信号，这样可以有效防止孩子连接WiFi或使用手机流量上网，我就没有兴趣玩了。

　　然后是干扰器的安装位置，如果干扰器不能穿墙使用，一定要安装在孩子的房间里，如果要防止干扰器被孩子发现或损坏，干扰器可以或者可以将防护罩安装在面向儿童门的位置，对安装后的正常影响不大，安装位置需要多考虑，可以安装在高处，防止儿童损坏防护罩。效果，还可以防止孩子损坏干扰器。

　　最后，GPS干扰器不需要整天打开，只有在孩子玩手机超过允许时间后才能打开，在孩子睡觉后关闭干扰器，也可以防止这就要求干扰器的打开和关闭要容易控制。

　　If you always hear the prompt "The user you dialed is temporarily out of service area" when calling your friend's mobile phone, don't think that he must be in the remote signal blind area. Maybe he just turned on GPS jammers that blocked the signal and turned the phone off.

　　With the development of science and technology, smart phones have gradually replaced traditional PCs and penetrated into all aspects of people's entertainment life. From a single call function in the past, to today's integration of calls, text messages, photos, Internet access, listening to songs, and e-books, mobile phones not only greatly meet people's communication needs, but also meet people's entertainment needs. While promoting communication, it also shortens people's life distance, unintentionally widens people's emotional distance, unifies facial expressions, and dulls spoken language.

　　Information needs are the natural needs of every social person. People living in society have group needs, isolation and lack of information are non-social characteristics. Information can remove people's uncertainty. There is a "use and fulfillment" theory in communication. "Use and Satisfaction" studies view audience members as individuals with specific "needs" and their media engagement activities as the process of "using" media based on the motivation of specific needs, so that those needs are "satisfied". Newspapers, radio and television media report a large number of current affairs news every day, so that people can understand what is happening in the world and eliminate the uncertainty of people's information. Mobile phone information carriers are more convenient, direct and fast than newspapers, radio and television information carriers.

　　The functions of mobile phones are getting richer and richer. From the initial calls, sending and receiving text messages, to later music, video playback and recording, and Internet access, it has greatly affected people's lives. A double-edged sword". It is necessary to correctly understand the various functions of the mobile phone and play its positive role. There are still many illegal photos, illegal videos, etc., which will violate the privacy of others.

　　Mobile phones have become an extremely important part of people's lives. Its function has changed from answering calls and texting to reading Weibo, playing games and even shopping. People are becoming more and more dependent on their mobile phones. "Human-machine communication" gradually replaced "interpersonal communication" leading to neglect of family affection.

　　The mobile signal jammer can be turned on after booting, which can not only block the WiFi signal, but also complete the synchronization effect of blocking the mobile phone signal. The signal bar on the phone will show zero bars. In this state, the phone can browse web pages, videos and play games online without Internet access.

　　Today's children play mobile phones and surf the Internet from a young age, and are especially interested in games. Maybe as a parent, as long as you love to play, your kids will love to play too. But the child is addicted to playing, it is difficult for you to control it. It is not that you say that he will not play.

　　Some may not have the heart to beat and scold the child.

　　In some respects, playing games can cultivate children's intelligence, but it is more harmful, because children's curiosity is very important , and self-control is poor, which will lead to children becoming addicted to mobile phones and indulging in the online world, which not only does not enhance the child's intelligence, but also affects the child's physical and mental health.

　　Faced with this kind of problem, I believe that many parents are aware of the seriousness of the matter, and it is urgent to control their children's Internet access, but directly confiscating their children's mobile phones will cause their children to be unhappy, and they end up crying to end the "battle". Is there any way to indirectly control children's Internet access?

　　GPS jammers can solve this problem.Without the Internet, the child will naturally not like to play.

　　In this case, it can meet the interference range requirements of a large number of people. In this modern society, with the rapid development of communication systems, cell phones have been widely used all over the world, but the continued use of cell phones has tormented many people. If you were one of them, what would you do?

　　Cell phone jammers are very important devices in modern electronic products. The mobile phone market continues to grow. The market for low-cost products in emerging countries is the main battlefield. With the popularization of smart phones, communications will develop rapidly. The introduction of 4G is encouraged not only in developed countries but also in many markets. Nowadays,cell phone jammer are indispensable in many places.

Does the mobile phone signal jammer work still indicate that some mobile phone signals still have signal indications? This is the wrong impression. In fact, the portable cell phone jammer was unable to communicate this time. When you press the pull button, you will find that the signal indicator goes out with some signal indications. Will the cell phone signal tank interfere with the work of other electronic devices? This is because the electromagnetic signal from the mobile phone signal jammer only shields the function of mobile communication, and can fully enter the working frequency band of mobile phones nationwide. Moreover, this signal is always in a relatively static state and has no effect on electronic equipment. Mobile phone jammer works in the later stage, does not damage the phone for a long time? Thank you for your attention. this is normal phenomenon. In design, we use aluminum alloy wire drawing machine to help dissipate heat. Therefore, the 3G/4G telephone jammer guarantees long-term stable operation. Therefore, the machine will not damage the heat engine. Make sure that the mobile phone signal jammer has a very weak electromagnetic signal strength. Please rest assured that the test data shows that the signal strength will not cause harm to the human body. At the same time, the mobile phone jammer only shields the forward signal of the mobile phone, so the mobile phone signal jammer cannot connect to the base station, and the mobile phone itself will not be damaged.

At the same time, the signal jammer only shields the forward signal of the mobile phone, so the signal jammer mobile phone cannot connect to the base station, and the mobile phone itself will not be damaged. Is there a difference between the distance used by mobile phone signals and outdoor equipment? The effective distance of the signal jammer (30-40 meters) generally refers to the indoor distance. In open outdoor areas, the effective shielding distance can reach hundreds of meters. Whether the signal jammer is indoors or outdoors, the effective length of the shielding, and the distance from the base station, it should be noted that they are related to general environmental conditions such as the installation location. Therefore, the use of mobile phone signal jammers needs to carefully consider this factor, so as not to block the blind spots and affect the shielding effect. Are GSM mobile phone signal jammers and CDMA signal jammer phones the same effect? Since the anti-interference performance of CDMA mobile phones is much better than that of GSM mobile phones, the signal jammer of the shielding distance of CDMA mobile phones is smaller than that of GSM mobile phones, but the difference is about 20-40 meters. However, if necessary, it is necessary to increase the number of signal jammers on the mobile phone to ensure the shielding effect of the signal jammer CDMA mobile phone, which will attract users' attention in some particularly important places.

At the same time, let's take a look at how WiFi and Bluetooth work. WiFi and Bluetooth are wireless devices that generally use the 2.4G frequency band to support short-distance data exchange. For families, this is also extremely convenient. With WiFi, you can reduce traffic expenses, browse the web and watch videos anytime, anywhere. For mobile phone lovers, there is no pressure at all. WiFi is cheaper for large enterprises because it allows multiple systems to be connected to one connection. We acknowledge that WiFi or Bluetooth provide great convenience for those who need to use them to send messages and files. However, using WiFi and blue technology, the privacy of your highly confidential files is likely to be attacked by hackers, because WiFi and Bluetooth have low capabilities for hackers. Secondly, both WiFi and Bluetooth can track your location, and anyone can easily know your location. And wifi jammer can play an important role to help eliminate potential dangers. This is why we need a WiFi signal jammer and a Bluetooth jammer.
