With the increasingly popular use of mobile phones, the number of mobile users in China has exceeded 900 million a few years ago. The current automation functions of mobile phones are constantly expanding. In addition to basic voice calling and short message functions, they also enjoy digital cameras, monitoring Camera, recorder, Internet access and more application functions. The application of these smart phones has greatly facilitated the communication and communication between people, the carrier of information, and enriched people's lives. However, while mobile phones are actively promoting social development, there are many problems caused by the proliferation of mobile phones. The disadvantages brought about, for example, in the production workshop or assembly line of some large factory enterprises:

Mobile phone signal jammer manufacturers analyze why they should install signal jammers in factories:

1. During production, workers often stop their work due to a sudden call or text message to answer the phone or reply to text messages.

2. Although some factories or enterprises require workers not to use mobile phones during work, there will always be unconscious people who take the opportunity to use mobile phones secretly.

3. Some workshops require a quiet operating environment, which often disturbs the working environment and affects the normal work of others due to a sudden ringing of someone's incoming call.

4. In some assembly lines, an employee answering a phone call or flipping through a mobile phone will cause the continuity of the entire assembly line operation and affect the production efficiency.

5. The production and processing process, processing technology, and product information of some enterprises are the commercial secrets of the enterprise, but at any time, individual employees with ulterior motives may easily use the functions such as taking pictures and videos of smartphones to remove the confidential information. vent.

6. There are also some chemical enterprises that belong to explosion-proof and flame-proof products, and it is necessary to strictly restrict and prevent the use of mobile phones in the factory area.

To sum up, the wide application of mobile phones is a double-edged sword, and the benefits brought by mobile phones need not be described too much, but for some special places, the use of mobile phones should be restricted or even prohibited. In some special places, such as workshops, the use of mobile phones is restricted. According to the traditional list of rules and regulations, personnel supervision, and punishment systems, it is impossible to completely eradicate and eliminate the proliferation of mobile phones. At present, it is more feasible from the perspective of technical products. The method is to install a mobile phone signal blocker or a mobile phone signal shielding system at an appropriate location in the factory area. Each mobile phone signal jammer can cover a certain area, and these coverage areas can be formed into an area of ​​coverage in the form of a cellular network. Achieve complete signal shielding of large areas.

Now the mobile phone signal shielding project has been able to do, for all types of mobile phone signals on the market: GSM (China Mobile, China Unicom), CDMA, DCS (1800MHz), PSH (PHS), 3G (including TD, WCDMA, CDMA200) , 4G, etc. are all effectively shielded. If the customer also needs to increase the shielding of WIFI and Bluetooth, it can also be added.

At present, the mainstream hand signal jammer manufacturers usually work in two ways:

1. Simply install a mobile phone signal blocker to achieve the most basic mobile phone signal blocking function.

2. The method of mobile phone signal jammer + intelligent control system is the most intelligent mobile phone shielding solution in the same industry in China. It can realize remote centralized control of any one or a group of mobile phone signal jammers, It can perform fault self-checking, alarming, automatic timing control, unattended operation and other humanized management functions for mobile phone signal jammers. +
