The components of a Signal Jammer typically include a main unit, antenna, and power cable. During the installation process, it is important to consider the potential interference from magnetic fields in the vicinity of the main unit, antenna, and power cable. Incorrect placement of the jammer can lead to interference with the emission of jamming signals, thereby affecting the effectiveness of the device.
- Minimum Height Requirement: The Signal Jammer should be installed at a minimum height of 1.8 meters above the ground. This ensures optimal coverage and prevents any potential obstruction that may hinder the jamming signals.
- Distance from Signal Towers: It is crucial to install the jammer far away from signal towers. The main unit, antenna, and power cable of the Signal Jammer are susceptible to interference from magnetic fields in their immediate vicinity. Incorrect placement can disrupt the emission of jamming signals, thereby compromising the effectiveness of the device. The closer the jammer is to a signal tower, the smaller its interference radius will be.
Installing Signal Jammers in schools plays a vital role in maintaining the integrity and fairness of examinations by preventing cheating through the use of mobile phones and other communication devices. However, it is essential to consider the installation location and specific details to ensure optimal performance. By adhering to the recommended guidelines, schools can effectively deter cheating and create an environment conducive to honest and unbiased assessments.
