Understanding the Technology Behind Signal Interference Devices
In today’s interconnected world, the need for uninterrupted communication has become paramount. However, there are instances where the use of mobile phones or other communication devices can be disruptive or pose security risks. This is where backpack signal jammers, also known as backpack shielders, come into play. This article aims to shed light on the principle and functionality of these devices, exploring how they effectively disrupt signals within a certain range, rendering communication devices unable to connect with base stations.

Principle of Operation:
The principle behind backpack signal jammers lies in their ability to emit signals in the same frequency range as the base stations of communication signals. By doing so, these devices interfere with the reception of valid signals transmitted by base stations, rendering mobile phones and other terminal communication devices unable to establish a connection. The interference caused by the emitted invalid signals disrupts or blocks the reception of valid signals, effectively impeding normal communication.
Software Integration in Shielder Modules:
It is worth noting that backpack signal jammers incorporate software within their mainboard modules. This software plays a crucial role in ensuring the efficient functioning of the device. By controlling the emission of signals within the desired frequency range, the software enables the shielder to effectively disrupt communication signals within its designated interference range.
Compatibility with Mobile Phone Brands and Models:
Contrary to popular belief, the effectiveness of backpack signal jammers is not dependent on the brand or model of the mobile phone being used. These devices primarily target the SIM cards within mobile phones, irrespective of the brand or model. As most mobile phones utilize SIM cards provided by the three major telecommunication operators – China Mobile, China Unicom, and China Telecom – they all fall within the interference range of backpack signal jammers.
Limitations on Communication within the Interference Range:
Once within the interference range of a backpack signal jammer, mobile phones have limited options for establishing external communication. Regardless of the mobile phone number being used, the internal design of backpack signal jammers ensures that all frequency bands associated with mobile phone communication can be disrupted within their interference range. This includes not only voice calls but also data transmission and Bluetooth connectivity. The only viable solution for communication within the vicinity of a signal jammer is to install a mobile signal amplifier to counteract its effects.
Backpack signal jammers play a crucial role in ensuring security and preventing disruptive communication within specific areas. By emitting signals that interfere with the reception of valid signals from base stations, these devices effectively disrupt the functioning of mobile phones and other communication devices. Understanding the principle and functionality of backpack signal jammers allows us to appreciate their significance in maintaining controlled communication environments.
