Nowadays, it has long been common to install signal jammers in the examination room during various examinations. Once a student taking the test enters the test, even if the student secretly brings a mobile phone or other electronic communication products into the test room, the presence of the signal jammer in the examination room will , the communication signals of these mobile phones or electronic communication products will be blocked, so that they cannot be used normally. This is the simplest and most effective solution to prevent students from cheating in exams through electronic products. However, now some customers will consult us, expecting to install more powerful anti-cheating products in the examination room, or hope that the new anti-cheating product has the function of blacklist and whitelist, and can identify the scene during the examination. Which mobile phone users and specific mobile phone numbers are there. Then the question arises: Does the signal jammer in the examination room have the blacklist recognition function?

First of all, you need to know clearly that the signal jammer in the examination room itself definitely does not have the identification function of blacklist and whitelist. For devices with these functions, the correct name should be called: mobile phone signal management and control system. The basic working principles and working methods of this kind of products are fundamentally different from those of the test room signal jammers. In addition, the control system of the mobile phone signal management system is more inclined to the function of the pseudo base station of the mobile phone.

Then, should the signal jammer in the examination room also be made with the function of blacklist and whitelist? Does the examination room in the school really need to identify the numbers of all mobile phone users within the examination room range during the examination? In fact, as long as we carefully analyze the actual examination process, we can know that these functions are not very effective in preventing cheating in the examination.

To prevent cheating during the exam, use the signal jammer in the exam room to directly block the normal communication of the mobile phone signal, which can simply and directly cut off the communication link of the mobile phone. And if you switch to a mobile phone signal control system, although it has the functions of identifying mobile phone numbers and setting a blacklist, this adds extra workload to the preparation and guarantee of the exam. For example, it is necessary to calculate in advance which mobile phone users should Whitelisted? Which mobile phone users should be set as blacklist? The coverage of the mobile phone signal management and control system needs to be strictly controlled. How can the coverage be accurately controlled? Once the mobile phone users of ordinary people around the school are absorbed, they will be set as blacklist users by mistake, which will have unnecessary impact on external users.

Therefore, the test room signal jammer is convenient and fast to use, and it will not have as many concerns as the mobile phone signal management system.

考场信号干扰器

2023.03.13-考场信号干扰器要不要具备黑名单识别功能？

如今，在各类考试过程中安装考场信号干扰器早已司空见惯，参加考试的学生，一旦进入了考试，即使该学生偷偷将手机或者其它电子通讯产品带入，也会因为有考场信号干扰器的存在，这些手机或者电子通讯产品的通讯信号都会被屏蔽，从而无法正常使用。这是防止学生通过电子产品进行考试作弊行为的最简单、最有效的解决方式。但是，现在有些客户会向我们咨询，期望在考场中安装功能更加强大的防作弊产品，或者说是希望新的防作弊产品具有黑名单、白名单的功能，能够在考试过程中，识别出现场有哪些手机用户和具体的手机号码。那么问题就出来了：考场信号干扰器要不要具备黑名单的识别功能呢？

首先需要明确知道是：考场信号干扰器本身是肯定不具备黑名单、白名单的识别功能的。具有这些功能的设备，正确的名称应该称之为：手机信号管理控制系统。这类产品与考场信号干扰器的基本工作原理、工作方式存在本质上的不同。另外，手机信号管理系统控制系统更偏向于手机伪基站的功能。

那么考场信号干扰器要不要也做成具备黑名单、白名单的功能呢？学校里的考场在考试过程中是否真正需要必须识别考场范围内的所有手机用户的号码？其实我们只要认真分析一下实际的考试过程，就可以知道这些功能在考试防作弊方面的作用并不大。

考试期间防作弊，使用考场信号干扰器直接阻断手机信号的正常通讯，可以简单、直接的切断手机的通讯链路。而如果换成手机信号管控系统，虽说具备了识别手机号码、设置黑名单的功能，但是这就给考试的准备和保障工作新增了额外多余的工作量，比如需要事先统计好哪些手机用户应该被设定为白名单？哪些手机用户应该被设置为黑名单？手机信号管控系统的覆盖范围需要严格控制，可覆盖范围怎么去精确控制？学校周边老百姓的手机用户一旦被吸收过来，错误的将期设置为黑名单用户，这样就会对外界用户产生了不必要的影响。

所以说，考场信号干扰器使用起来倒时方便、快捷，不会像手机信号管理系统那样存在众多顾虑。
