Understanding the Capabilities and Upgrades of Full-Band Interference Devices in Blocking Cheating Signals
In various examinations, such as national civil service exams and English proficiency tests, full-band interference devices are used to block cheating devices. However, many people are unaware of how these devices work and the types of signals they can block. Today, we will shed light on the capabilities of full-band interference devices and their ability to shield various signal types, including the unfamiliar VIFI signal, to eliminate any opportunity for cheating. Additionally, the types of signals blocked by these devices vary based on their frequency bands. As technology continues to advance rapidly, most interference devices can now block 4G signals. However, with the gradual introduction of 5G technology, these devices must also be upgraded to become 5G blockers.

The Advancements in Full-Band Interference Devices
In the industry, full-band interference devices that support the blocking of 5G signals have been successfully developed and introduced to the market. The market feedback regarding the interference of mobile 5G signals has been highly positive. As mentioned earlier, the types of signals blocked by interference devices vary based on their frequency bands. With the rapid advancement of technology, most interference devices can now effectively block 4G signals. However, as 5G technology gradually becomes more prevalent in China, these devices must be upgraded to become 5G blockers to maintain their effectiveness.
The Challenge of UHF and VHF Signals
Some individuals with malicious intent use UHF and VHF signals to transmit cheating signals. These signals are typically used for walkie-talkies, but these individuals exploit them by creating low-power transmission devices and selling receivers to cheating candidates. They then transmit the exam answers through these devices. If full-band interference devices incorporate interference modules for UHF and VHF signals, it would further enhance their effectiveness. By staying at the forefront of technology, the industry has successfully developed full-band interference devices that can block 5G signals, providing a comprehensive solution to combat cheating.
The Importance of Technological Advancements
In order to remain competitive in the industry, full-band interference devices must continuously update their technology. Failure to do so will result in their obsolescence. These devices are primarily used to block mobile signals, and their effectiveness is undeniable. However, as technology advances, it becomes crucial to expand the range of signals that can be blocked. This includes WiFi signals, UHF signals, VHF signals, and interference in specific frequency bands. Our company specializes in customizing full-band interference devices to meet these specific requirements.
