It is also common to use signal blockers in standardized testing facilities. Generally, signal jammers used in standardized examination rooms are mainly used to block wireless signals, such as Wi-Fi and Bluetooth signals, to prevent candidates from cheating during the exam through wireless networks or Bluetooth devices. At the same time, in order to ensure the safety and fairness of the examination environment, other types of signal jammers will also be used.
Different types of standardized tests may use different types of signal jammers or a combination of signal jammers. For example, Wi-Fi blockers and cell phone signal blockers are often used in exam rooms to prevent candidates from cheating using smartphones or other communication tools.
In short, the use of jammers in standardized testing situations is to maintain the fairness and security of the test. The specific jammer model and technology used may vary by exam and region, but the use of jammers should comply with relevant laws and regulations and should only be used during the exam.
Different standardized tests may require different types of maskers. Here are some types of jammers that may be used:
Wireless signal jammer: This jammer can block wireless network signals, including Wi-Fi and Bluetooth signals. They prevent cheating by effectively preventing candidates from using wireless devices to communicate with the outside world.
Mobile phone signal jammer: This type of jammer is mainly used to block mobile phone signals to prevent candidates from using their mobile phones to receive/send messages or make calls. It can effectively prohibit mobile phone communication functions to ensure the fairness and security of the exam.
GPS signal jammers: GPS jammers may be used on certain standardized tests where positioning devices need to be prevented from cheating. It can interfere with or block Global Positioning System (GPS) signals, preventing candidates from using location-based technology to obtain external information.
It should be noted that the specific type of jammer used depends on the requirements of the exam institution and the exam schedule. Different exam bodies may use different technologies to ensure the fairness and security of exams.
