In the exam season each year, many parties are gradually anxiously planning the examination work, and the invigilators have their own tricks to avoid new technology fraud. Among them, the special test room Selectable Portable Gps Wifi 3G Cell Phone Signal Jammer is still a counteracting jammer. As a well-known manufacturer of mobile phone jammers, there are various types, models and specifications of mobile phone signal jammers. The application party should determine its own requirements before purchasing. cell phone jammer In order to prevent the poor actual shielding effect from causing safety accidents in the examination room, we are still paying attention to the accuracy of the operation method.
First of all, I want to establish the application site. Most of the original test site type Selectable Portable Gps Wifi 3G Cell Phone Signal Jammer are suitable for long-term work and are durable.
Secondly, how big are we in the shielded area?
For example, for a house of 100 square meters or a site of over 1,000 square meters, the output power must be larger if the total area is large, and the shielded output power must be adjusted if the total area is small. And what frequency band must be blocked, is China Mobile, China Unicom, telecommunications network, and CDMA all blocked?
Or only a part of the frequency band must be shielded. In order to achieve the best practical effect when choosing a suitable cell phone jammer, you also need to look at the application skills. Among the most important aspects are the following: The room-type mobile phone signal jammer is proposed to be placed at a height of 180cm-220cm from the ground, and the viewing angle is preferably extended. Is there an obstruction (such as wall, metal, body, etc.) between the mobile phone signal jammer and the wireless communication equipment (mobile phone, etc.).
The electromagnetic interference sent by the jammer will have a different level of attenuation coefficient after passing over the obstruction, please try to reduce it as much as possible. The weaker the wireless communication receiving sensitivity in the application conditions, the stronger the actual shielding effect of the basic theory of the mobile phone signal jammer. The longer the distance between the mobile phone jammer application scenario and the communication base station, the stronger the actual shielding effect of the basic theory of the mobile phone signal jammer.
into the considerations and technical aspects involved in selecting and deploying Selectable Portable Gps Wifi 3G Cell Phone Signal Jammers, particularly in the context of exam invigilation.
1. Understanding Requirements Before Purchase:
- Before purchasing a cell phone jammer, it's crucial for the application party to assess their specific requirements.
- Factors to consider include the size of the application site, the desired coverage area, and the frequency bands that need to be blocked.
- Determining these factors beforehand ensures that the selected jammer meets the necessary specifications to effectively fulfill its intended purpose.
2. Types and Specifications of Jammers:
- As a reputable manufacturer of mobile phone jammers, there are various types, models, and specifications available to suit different needs.
- The choice of jammer depends on factors such as the duration of operation, durability, output power, and frequency bands to be blocked.
- For exam rooms or test centers, selecting a jammer that offers precise and reliable performance is essential to prevent cheating and maintain the integrity of the examination process.
3. Placement and Application Skills:
- Proper placement of the cell phone jammer is critical to maximize its effectiveness.
- It is recommended to position the jammer at a height of 180cm-220cm from the ground with an extended viewing angle.
- Consideration should be given to any obstructions, such as walls or metal structures, that may interfere with the signal propagation and attenuation.
- Understanding the electromagnetic interference and signal attenuation coefficients associated with the application environment helps optimize the placement of the jammer for optimal performance.
4. Wireless Communication Sensitivity and Distance from Base Station:
- The sensitivity of wireless communication devices in the application environment directly impacts the effectiveness of the jammer.
- Weaker wireless communication sensitivity results in stronger shielding effects from the jammer, as the signals are more susceptible to interference.
- distance between the jammer and the communication base station influences the shielding effect, with longer distances typically resulting in stronger interference.
selecting and deploying a Selectable Portable Gps Wifi 3G Cell Phone Signal Jammer requires careful consideration of various factors, including site requirements, jammer specifications, placement techniques, and environmental conditions. By adhering to these considerations, exam invigilators and application parties can effectively prevent cheating and maintain the integrity of examinations.
