Whenever the exam is approaching or before the end of the semester, we will often receive a consultation from a student's parent, wanting to purchase a mobile phone signal jammer suitable for home use from me. The main purpose is to help students study at home. In this section, students are prevented from being addicted to using handheld game consoles such as mobile phones or PADs to delay their learning progress and lead to a serious decline in their academic performance. We know the good intentions of the parents and hope that the children can concentrate on their studies. However, in the face of such inquiries and demands, we usually answer them briefly and refuse to provide products. Why do we not recommend families to buy mobile phone signal jammers to limit What about children using mobile phones?

First of all, analyze from the perspective of children: students have already experienced a day's learning process at school during the day, and the self-study process after returning home mainly relies on self-consciousness and initiative, and proper learning and relaxation should be recognized. A combination of work and rest will produce a better learning effect. If students are forced to keep learning all the time, they will not be able to relax physically and mentally, coupled with the use of mobile phone signal jammers to restrict children, it will often backfire and make children rebellious, which will not only prevent children from concentrating on their studies, but even It will also make children try to find other ways to break through the limitations, or use other methods to resist learning.

Let's analyze it from the perspective of parents: the demand put forward by parents for mobile phone signal jammers seems simple, although at the beginning it was only a request to shield the signal of the child's mobile phone or the room where the child lives. However, these parents will immediately put forward more additional requirements: in addition to requiring cheap products, there are more restrictions and requirements on the use environment and functions. These requirements are summed up, including but not limited to These are listed here:

1. The mobile phone signal jammer purchased is best to only shield the signal in the child's room, but at the same time keep the signal in the parent's room, so that the child cannot use the mobile phone to surf the Internet, but the parent can use the mobile phone normally in other rooms;

2. It is best to turn on the mobile phone signal jammer without the child noticing it, or install the shielding device next to the child's room. The shielding signal can penetrate the wall to achieve signal shielding;

3. The mobile phone signal jammer is preferably small and exquisite, with a very small appearance, can be powered by a battery for several hours or can automatically set the power-on and power-off time. The size of the shielding device is best grasped with one hand, or hidden in a bag or clothes;

4. The mobile phone signal jammer should be able to block the mobile phone number. For example, if the child's mobile phone number is set, then only the child's mobile phone signal will be blocked, and other mobile phone numbers in the same family can be used normally;

5. Since the houses of many families are multi-storey residential buildings, it is also necessary to consider that when using mobile phone signal jammers at home, it cannot affect other neighbors on the upper and lower floors, so as to avoid complaints from neighbors because of this;

Judging from the above requirements, some functional requirements have actually exceeded the capabilities of our mobile phone signal jammer manufacturers, and some functional or restrictive requirements are self-contradictory. That's why we don't recommend buying a cell phone jammer for families.
