Important Factors to Keep in Mind for Effective Selection and Installation of Mobile Phone Jammers in Examination Halls
As the exam season approaches, many schools are preparing to purchase and install mobile phone jammers in their examination halls. The selection and installation of these devices are crucial considerations for customers. Different product models have varying functionalities, usage methods, and installation procedures. Therefore, it is important to address the following questions: What should be considered when selecting mobile phone jammers for examination halls? Where should they be installed?
Selecting the Style of Mobile Phone Jammers:
Currently, the mainstream products in the market adopt an internal antenna structure. This style offers advantages such as a sleek and attractive appearance, eliminating the need for complex assembly and connections. To install and use these jammers, simply connect the main unit to a power source and switch it on.
However, there are still traditional models available that feature an external antenna. These products have maintained their appearance for over a decade. It is important to note that the modern mobile phone jammers that support 2G, 3G, 4G, 5G, and other frequency bands typically require at least 10-12 omnidirectional antennas. When these antennas are individually attached to the main unit, the overall appearance may not be aesthetically pleasing and can resemble a “hedgehog.” Additionally, the exposed antennas are susceptible to damage and can be easily tampered with. If not installed using a fixed or wall-mounted method, each use requires the removal or tightening of the antennas, which increases the workload and the risk of loose or improperly secured antennas, leading to potential malfunctions.
When installing mobile phone jammers in examination halls, the location is of utmost importance. If wall-mounted, it is recommended to install them at the upper ends of the blackboards on either side of the classroom, approximately 2-3 meters above the ground. This placement helps prevent students from intentionally touching or damaging the jammers. Alternatively, they can be installed on the central walls of the classroom. Both positions can achieve optimal coverage.
For temporary and non-fixed installations, it is advisable to place the jammers above the teacher’s podium or in a corner of the classroom. It is essential to have a supporting surface such as a desk, chair, or bookshelf to elevate the device from the ground. Placing the mobile phone jammers directly on the floor significantly reduces the transmission distance and coverage range of the signal.
In conclusion, selecting and installing mobile phone jammers in examination halls requires careful consideration. Opting for modern internal antenna models offers advantages in terms of appearance, ease of installation, and usage. However, traditional external antenna models are still available in the market. When installing these devices, it is crucial to choose appropriate locations that prevent tampering and ensure optimal coverage. Placing the jammers directly on the ground should be avoided to maximize their effectiveness. By following these guidelines, schools can effectively maintain the integrity of examinations and prevent unauthorized mobile phone usage during tests.
