Prison type mobile phone signal blocking equipment

Shenzhou Mingda is a professional mobile phone signal blocking service provider. We have developed and produced a series of prison-type mobile phone signal shielding equipment. The main model is B mobile phone signal shielding equipment. It is a high-power mobile phone signal shielding equipment specially developed and produced using international advanced shielding technology in response to market demand. The equipment adopts power design, with stronger shielding effect, wider shielding range and more stable performance. It is suitable for a variety of large confidential places, especially prisons and detention centers. It has successfully solved shielding problems for many prisons.

Performance Optimization

Power design greatly enhances equipment working efficiency, wider shielding range, and can last for years of uninterrupted operation

Working Principle
/>
Within a certain frequency range, mobile phones and base stations are connected through radio waves, and data and sound transmission are completed with a certain baud rate and modulation method. The shielding device scans from the low-end frequency of the forward channel to the high-end frequency 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, achieving the purpose of blocking the mobile phone signal. The mobile phone shows no signal and no service when searching the network. system phenomena.

China Mingda applies its original digital point frequency hopping technology and pilot synchronization technology to The signal is effectively shielded. Due to the point frequency technology frequency tracking, there is no waste of electromagnetic power outside the frequency point. At the same time, the shielding power after synchronization can accurately act on the downlink pilot time slot to eliminate interference with the base station and greatly reduce electromagnetic radiation. Therefore, for extremely strong signals The shielding efficiency is extremely high, while the electromagnetic radiation is only tens or hundreds of percent of that of the frequency sweep method, which not only reduces the energy attenuation of the machine itself, but also ensures the safety and health of the surrounding people, achieving true green environmental protection.

Although B is a high-power machine, due to its optional antennas at various angles (directional and omnidirectional) and the use of high-gain antennas dedicated to base station broadband, it avoids affecting normal signals to surrounding residents. interference. B Each module is equipped with a power indicator light to detect the normal working status of each module. At the same time, the design of the single module is also designed to facilitate future product upgrades.

B High-power mobile phone signal shielding equipment has a wide shielding range, unique design, superior quality, and comprehensive shielding frequency band characteristics, which determines that it will become the first choice for high-end large-scale confidential places!
