Learn about 5G signal jammer

by LIU YIFA 31 Jan 2024

5G jammers have become standard testing equipment in examination rooms, such as high school entrance examinations, postgraduate examinations, civil service examinations, and various qualification certification examinations. Through signal shielding, candidates can contact the outside world through wireless signals (mobile phones) to prevent cheating in the examination room.

Its working principle is to use frequency multiplication, frequency division filtering and other technologies to analyze the required shielding frequency for the upper and lower channels of the mobile phone system, customize the shielding gap according to the shielding power, and automatically pass the mobile phone receiving station and wireless in the designated frequency band. The frequency of the router creates a shielding magnetic field.

Generally speaking, if a signal jammer for 5G is used in the examination room, it is generally recommended to have one in each room. This type of equipment is less powerful and does not require waterproof and rainproof equipment.

However, due to the large shielding range of outdoor mobile phone signals, the shielding distance can reach several hundred meters. Generally speaking, screening is used outdoors when the entire building requires screening. Achieving adequate distance for such distant areas requires the use of signal shielding with more power than required.

Therefore, for large outdoor areas, it is recommended to use high-power outdoor shielding. The casing can be waterproof and rainproof. If the equipment is not shielded, a rain cover is required. Therefore, the 5G signal jammer should be installed in a well-ventilated place, the antenna installation should try to avoid blocking large objects, and the antenna should be oriented towards the building that needs to be blocked.

The shielding distance of a signal shield is related to the environmental conditions at the time, such as the distance from the base station and whether there are signal isotopes in the surroundings. The installation and use of 5G signal jammers should fully consider this factor to avoid blind spots in shielding and affect the shielding effect.

What is Lorem Ipsum? Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum. Why do we use it? It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).
