Considerations for Choosing the Right Signal Blocker

Ensuring Effective Shielding Measures during Exam Season

As the exam season approaches, preparations for the rigorous examination process begin, with invigilators devising various methods to prevent high-tech cheating. Among these measures, the Signal Blocker remains an effective solution. However, it is crucial to understand the different types and models of Signal Blockers before making a purchase. This article aims to provide guidance on selecting the appropriate jammer to avoid any adverse effects on the shielding performance during exam sessions.

Consideration 1: Placement and Height

For indoor Signal Blockers, it is recommended to place them at a height ranging from 180cm to 250cm, with a slight forward tilt. This positioning ensures optimal coverage and effectiveness in blocking unwanted signals.

Consideration 2: Obstructions

It is essential to assess whether there are any obstructions, such as walls or metallic objects, between the jammer and the communication devices, particularly mobile phones. The interference signals emitted by the Signal Blocker may experience varying degrees of attenuation when passing through obstacles. Therefore, it is advisable to minimize such obstructions to maximize the jamming effect.

Consideration 3: Distance from Base Stations

The effectiveness of the jammer’s shielding capabilities increases as the distance between the jamming environment and the base stations increases. Therefore, it is preferable to select a jammer that can provide stronger shielding effects when operating in environments farther away from base stations.

When it comes to selecting a Signal Blocker, it is crucial to consider various factors to ensure its optimal performance during exam seasons. By carefully assessing the placement, minimizing obstructions, and considering the distance from base stations, one can make an informed decision and avoid any potential incidents in examination halls. Ultimately, the right Signal Blocker will contribute to maintaining the integrity and fairness of the examination process.
