Performance and Principle of Pull-bar Box Shielder for Mobile Phone

Performance and Principle of Pull-bar Box Shielder for Mobile Phone

  • 2022/05/10

Many users who use the pole box mobile phone shield do not know how it works, and often use it beyond the frequency range, resulting in poor results.

The formation of mobile communication work is that in a specific frequency range, wireless devices (mobile phones, etc.) and base stations are connected by radio waves to complete data and sound transmission at a specific baud rate and modulation mode. When the mobile phone communicates with the base station, it connects with the base station through the upstream frequency, and then transfers the signal to the Mobile Business Exchange Center for call or data connection. When the mobile phone is in standby, first the mobile phone sends a signal to the base station to register with the network, so that the mobile phone can get in touch with the base station. Once the demand for mobile phone calls is displayed, at the first time, the mobile phone is assigned to the mobile phone business channel according to the actual conditions of the channel near the mobile phone, so that the mobile phone can jump to the business channel and complete the call and data transmission. At the same time, wireless communication must ensure sufficient signal-to-noise ratio to complete reception and effective communication.

Therefore, the interference range will be affected by the field strength in the interference area when the pole-box mobile phone shielder is working at a certain power. It is important to know that no matter how high power the pole-box mobile phone shielder is, as long as the transmission power is a fixed value, the interference signal strength of the pole-box mobile phone shielder will be attenuated and the interference ability will be attenuated as the distance increases. This is why the interference range of the pole-box mobile phone shield is also different under different signal field intensities. Nanjing Baikang Mechanical and Electrical Technology Co., Ltd., a manufacturer specialized in producing pull-bar box mobile phone shield, can customize the scheme according to your needs.
