There are many types and models of shielding devices. Before purchasing, you must first clarify your needs and be targeted to achieve twice the result with half the effort. First of all, let us briefly understand the basic points that should be understood in the purchase of shielding devices.
The basic principle of shielding? Within a certain frequency range, the mobile phone and the base station are connected by radio waves, and the data and sound transmission is completed with a certain baud rate and modulation method. The jammer scans from the low end frequency of the forward channel to the high end at a certain speed during operation. This scanning speed can cause garbled interference in the message signal received by the mobile phone. The mobile phone cannot detect the normal data sent from the base station, so that the mobile phone cannot establish a connection with the base station and achieve the purpose of shielding the mobile phone signal. No service system, etc.
What factors affect the shielding effect? In the actual use environment, the interference signal emitted by the wireless signal jammer is affected by various factors. 1. The placement of the jammer. Indoor-type shielding device is recommended to be placed at a height of about 180cm-220cm above the ground, preferably inclined forward. 2. Whether there are obstructions (such as walls, metal products, human bodies, etc.) between the jammer and wireless communication equipment (mobile phones, etc.). The interference signal emitted by the jammer will be attenuated to different degrees after passing through the obstruction, please try to avoid it. 3. The original wireless communication signal strength in the application environment of the jammer. The weaker the wireless communication signal strength in the use environment, the stronger the theoretical shielding effect of the jammer. The distance between the jammer application environment and the communication base station. The farther the jammer application environment is from the base station, the stronger the theoretical shielding effect of the jammer.
How to choose the most suitable jammer?
First of all, the types of shields that should be selected for different shielding areas are different: in general, there are two types of shields: indoor and outdoor. The former is smaller than the latter in terms of volume and actual output power of the interference signal. Relatively, its production cost and selling price are also lower. If the area to be shielded is a small and medium-sized indoor environment with a simple structure (such as classroom; examination room; office; meeting room; lounge; bathroom, etc.), and the actual area is not more than 100 square meters, then choose a small and medium-sized indoor shielding device Suitable. If the area to be shielded is large and empty (such as warehouses; squares; auditoriums and conference venues, etc.), large outdoor shields can be considered. If the area to be shielded is a large indoor space and the structure is more complex, the most ideal The shielding scheme is generally a combination of size: that is, a certain number of mainframes are deployed in a cellular manner to cover a large area, and a certain amount of minicomputers are used to eliminate blind spots, so as to achieve the most ideal shielding effect within a reasonable budget.
MDPB-5E (6 channels) upgraded mobile phone signal jammer is a mobile phone signal jammer specially developed and produced by adopting international advanced shielding technology to meet market demand. The equipment has undergone a brand-new upgrade, changing from 5 channels to 6 channels increases the shielding effect of the device itself on the signal. At the same time, the newly added 4G frequency band solves the disadvantages that other products cannot shield the 4G frequency band, and the shielding effect is superior to other similar products. The shielding effect is stronger, the performance is more stable, and it is easier to be recognized and accepted by customers. The upgraded version of MDPB-5E (6 channels) can automatically form a shielding magnetic field within the specified range when entering the working state, and forcibly disable mobile phone signals. The upgraded version of MDPB-5E (6 channels) only shields mobile phone communication signals. It does not interfere with other electronic equipment, which has become its rare advantage. The advent of the MDPB-5E (6 channel) upgraded version of the mobile phone signal jammer may completely solve the harm caused by the information leakage of communication facilities to users, allowing people to enjoy the speed and convenience brought by high-tech to mankind while ensuring The security of its information.
