As a core hub for economic operations, the financial industry carries out critical functions such as capital flow, information exchange, and risk management. Its security and efficiency are directly linked to the stability of the economic order. In the digital age, the widespread use of electronic devices such as mobile phones has brought convenience, but it also poses potential risks to the...
Theaters are artistic spaces where light, shadow, and sound intertwine. The immersive quality of a film and the powerful impact of a play require audiences to experience them quietly and undisturbed. However, the sudden ringing of mobile phones, the glare of screens, and the subtle sounds of candid cameras and recordings gradually erode the integrity of this artistic experience. The advent of...
To ensure that the selected shielding equipment truly meets the use needs and has safety and compliance guarantees, please be sure to pay attention to the following points:
1. Clarify the use location and coverage area
First, confirm the use environment (such as classrooms, conference rooms, prisons, examination rooms, etc.) and the space range that needs to be shielded, so as to select...
Currently, most mobile phone signal jammers on the market are full-band interference devices that can effectively shield mainstream communication and wireless network frequencies and adapt to various complex environmental requirements. Its main shielded frequency bands include:
Mobile communication frequency band
CDMA: 867–885 MHz (China Telecom 2G)
GSM: 923–960 MHz (China...
Communication signal jammers are usually equipped with a variety of RF modules, covering a wide frequency band of about 20MHz to 6000MHz to adapt to different usage scenarios. For special needs, quickly replacing RF modules is a key operation to ensure the flexibility of the equipment. However, the replacement of RF modules must follow certain specifications to avoid equipment damage...
In different application scenarios, a full-band signal jammer can usually be configured with an omnidirectional antenna or a directional antenna to achieve differentiated control of the signal interference effect. Compared with the "360° uniform coverage" of an omnidirectional antenna, a directional antenna mainly concentrates energy to emit in a specific direction, and has a...
The core purpose of installing drone jammers in a certain reservoir is to prevent multiple security risks that may be caused by drones illegally entering the airspace of the reservoir area. This measure is closely related to the protection of key infrastructure, airspace control requirements and actual application scenarios. The following analysis is carried out from five dimensions:...
What is signal jamming?
Signal jamming is the intentional disruption or disruption of wireless communications signals, such as radio waves, cellular signals, Wi-Fi, GPS, and satellite communications. Jamming occurs when a signal jammer transmits a signal that blocks or disrupts normal data transmission, causing the target communication system to degrade or become completely unusable....
In this era of information explosion, enterprises, institutions and government agencies face two major challenges when holding meetings: mobile phone interference and information leakage. Frequent call reminders and information vibrations during the meeting not only interrupt the rhythm of the meeting, but also may bring unpredictable information security risks. In order to effectively respond...
