In fact, mobile phone jammers are no longer a new thing abroad, and they have begun to be sold on the Chinese market in the past two years. Some radio enthusiasts have even developed a set of design drawings and published them on the Internet. The principle is actually very simple. In layman's terms, it is like "speaking loudly than talking softly."
Regarding the working principle of this equipment, there is such a professional description:
"The working principle of a mobile phone is that 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 at a certain baud rate and modulation method. For this communication principle, the mobile cell phone jammer scans from the low end of the forward channel to the high end at a certain speed. This scanning speed can cause garbled interference in the message signal received by the mobile phone, so the mobile phone cannot detect the signal sent from the base station. With normal data, no connection can be established with the base station."
Since it only interferes with the downlink signal, this kind of mobile phone jammer device will not affect the mobile base station or the normal use of other electronic devices.
Therefore, in the propaganda of the merchants, this equipment is called:
"Adopting foreign advanced technology, mainly for small places at home and abroad that require safety and confidentiality, such as private bosses, confidential offices, negotiation rooms, mobile vehicles, mobile Political and business dignitaries guard the scene, etc., and carefully developed high-tech products based on the actual situation of mobile communications at home and abroad... Give you a security and a peace."
- Cell phone jammers are becoming increasingly popular around the world and have also gained popularity in the Chinese market in recent years.
- This expansion is attributed to the efforts of radio enthusiasts who develop and share design blueprints online, making the technology more accessible.
- The core principle of a cell phone jammer is relatively simple, similar to speaking loudly to drown out a conversation.
From a technical perspective, cell phone jammers work by disrupting the connection between a cell phone and a base station. They do this by scanning radio frequencies within a specific range, thereby interfering with the information signal received by the phone. This interference prevents the phone from detecting the base station's signal, making it impossible to establish a connection. Importantly, this interference only affects downlink signals, ensuring that it does not interfere with the operation of mobile base stations or other electronic devices.
- Merchants promoting these devices often emphasize their ability to protect privacy and confidentiality in a variety of environments, such as private homes, confidential offices, negotiation rooms, and vehicles transporting political or business dignitaries.
- By leveraging advanced technology, these jammers provide a sense of security and peace of mind for users seeking to maintain confidentiality and prevent unauthorized communications.
The popularity of cell phone jammers highlights the growing demand for solutions to address privacy issues and ensure information security in an increasingly connected world. As technology continues to develop, these devices are likely to remain an important tool for individuals and organizations seeking to protect sensitive information and maintain control over communication channels.
