Signal jammers are very popular in every country. As a world economic power, the demand for jamming devices such as mobile phone jammers is also increasing. The jammer purchased a signal jammer, which is used exclusively in manufacturing and sales stores. , Mainly used to provide security and protection measures for major industries in the United States. The following is the sales diary of our store in August, which records the most popular signal jamming devices in the United States and other related matters. Of course, if you need to use it in a larger place, the interference range will be greater, and there is no need to worry about power problems. Then a desktop signal jammer is a good choice, it will interfere with the price of handheld devices, depending on how you need to buy, but we guarantee that we will provide higher quality equipment, you can buy with confidence.
Considering the large building area and the high requirements of the location, it is necessary to use a high-power signal jammer. Such devices have widespread interference. Block all calls within the specified range. You can also prevent interference to cell phone signals outside this area. Practicality is very powerful. You can work continuously. Enhanced blocking function. It can be said that this is a special equipment installed in special places such as camps or military centers. It is evenly distributed in the blocked area. Ensure the necessary shielding effect. This is a goal that ordinary mobile phone jammers cannot achieve. It is highly reliable. As a special cell phone jammer in prisons and other special places, this product completely covers the frequency band of your cell phone.
When introducing each radio frequency jammer, we emphasize that the interference range of the jammer is for reference only, please refer to the actual situation. The interference range depends on the local signal strength. Here, we will try to explain why the manufacturer’s scope of work is often different from the actual situation. First, after the jammer is manufactured, it will be tested. There are many necessary tests, such as battery life, transmission frequency, etc., including testing the interference radius. Manufacturers always believe that the test results are more valid than the actual range, because these devices are usually tested in open spaces. You know that buildings and different concrete structures can hinder signal transmission. Most of us live in big cities, surrounded by high-rise buildings. The signal strength of the local mobile phone is also an influencing factor. Therefore, don’t be surprised if the interfering device cannot block a phone within 30 meters of you.
Move the jammer to ensure the quietness of the venue
Mobile phones are an important communication tool in today's society. With the development of mobile phones, mobile phones are not only a communication tool, but also an essential device in our lives and work. It enriches our entertainment life so that we can learn more about the outside world and keep up with the times. A mobile phone is a device that needs a signal to work, and a mobile phone without a signal is like a brain without a brain. With the development of science and technology, mobile phone signals are gradually upgrading. From the initial 2g and 3g to the current 4g, the speed has been greatly improved, which can meet people's needs for the Internet. The mobile phone interference signal is the signal of the mobile phone, and the use of the mobile phone is prohibited here. For example, in a large conference room, mobile jammers will need to be used to ensure the quietness of the venue. For example, in schools, in order to make students study hard, they cannot deceive mobile phones and install mobile phone jammers during exams.
Although recent news indicates that some prisoners sometimes use mobile phones to access the Internet, the Ministry of Justice has just announced that French prisons will use a new type of "high-tech" jammer. Your cost has not been stated. After the Charlie Hebdo attack and Manuel Valls' announcement, Christiane Taubira yesterday announced the outline of the plan entitled "Counter-Terrorism Justice" (PDF). In the next three years, a total of 181 million euros will be released, of which 110 million euros will be released in 2015. Therefore, the prison administration will benefit from 43 million euros of protection funds, part of which will be used to "fill high-tech mobile phone jammers." However, Place Vendome has not yet provided a deployment plan.
The criminals used a new tonic to attack vehicles, mainly freight vehicles. Understand how jammers or signal blockers work, and discover key ways to prevent theft. Interference is a portable device that can block signals from GPS, GSM, 2G, 3G, 4G LTE cellular phones, UHF and VHF radios, WiFi and Nextel. The system emits low-frequency radio waves, which may interfere with the connection and prevent signals from being sent and received into restricted areas. Usually, signal jammers are used in security areas in military yards, airports, prisons, business meetings, and places where confidentiality is required. Nowadays, jammers are also used to smuggle freight vehicles.
