Yellow Screen for Phone Blocks Radiation Prevent Noise Pollution

Then there is the reliability of the actual effect of shielding, because whether it is a junior high school, high school or college entrance examination, the time period for one test is not short, and there are 2 tests in one day. If the actual effect of the ordered Yellow Screen For Cell Phone Blocks Radiation is not stable, there are If the data signal cannot be reasonably shielded for a period of time, it is very easy for candidates to use this time gap to carry out personal behavior of cheating, which will make the work of preventing high-tech cheating fall short. At the same time, the mobile phone signal jammer in the examination room should preferably have low noise during operation, which will not easily disturb the candidates who have already started the examination, and will not endanger the safety of the candidates and invigilators.

In some cases, the use of mobile phones and other communication devices is prohibited in various examination rooms, conference rooms, gas stations, oil depots, churches, hospitals, courts, military centers, libraries, theaters, etc. In order to prevent the use of mobile phones in these places, mobile phone shielding films are used to block mobile phone signals. However, in some cases, such as when taking exams in the examination room, in addition to blocking mobile phone signals, other communication devices including walkie-talkies, Bluetooth headsets, etc. also need to be shielded.

Can the multifunctional wireless signal blocker block the walkie-talkie?

In fact, the multi-function cell phone jammer is aimed at the uplink and downlink channels of the mobile phone system. It uses frequency multiplication, frequency division, frequency hopping filtering and other technologies to analyze the required shielding frequency; customize a spherical shielding space according to the power of the shield, and automatically within the specified range. The formation of a shielding magnetic field can make the mobile phone within the specified range ineffective in sending and receiving signals, unable to dial out and dial in, and unable to access the Internet, thereby achieving the purpose of forcibly disabling mobile phones. As long as the frequency band used by the walkie-talkie is shielded, the use of the walkie-talkie can be effectively shielded.

The concern over the reliability of shielding effects is valid, especially considering the extended duration of exams and the potential for multiple tests in a day. If the effectiveness of Yellow Screen For Cell Phone Blocks Radiation is inconsistent or unstable, there's a risk that candidates may exploit gaps in signal shielding to engage in cheating activities. This could undermine efforts to prevent high-tech cheating and compromise the integrity of the examination process.

Moreover, it's crucial that mobile phone signal jammers operate with minimal noise to avoid disrupting candidates who are already undertaking exams. Ensuring a balance between effectively blocking signals and maintaining a conducive testing environment is essential to safeguarding the fairness and security of examinations.

Pocket-Size 3G Wireless Cell Phone Jammer

Beyond examination rooms, various other venues such as conference rooms, gas stations, hospitals, and military centers also require restrictions on communication devices like mobile phones. In such cases, multifunctional wireless signal blockers play a vital role in not only blocking mobile phone signals but also other communication devices like walkie-talkies and Bluetooth headsets.

The functionality of these blockers lies in their ability to analyze and customize shielding frequencies using advanced technologies such as frequency multiplication and division. By creating a shielding magnetic field within a specified range, these blockers render mobile phones ineffective in sending and receiving signals, preventing them from making calls or accessing the internet. And by extending this capability to the frequency bands used by walkie-talkies, these blockers effectively neutralize their usage as well, reinforcing security measures across various environments.
