Blocking Gps On Cell Phone Or Tablet Can Block A Large Area
The standard classroom of the school is generally about 75 square meters, and each classroom can be equipped with a Blocking Gps On Cell Phone Or Tablet device to achieve better results. It can be placed in the middle of the classroom and can be shielded in a large area. Of course, this should be determined in conjunction with the power wiring. It is also common to place a shield on the podium. If it is a larger classroom or there is a base station nearby, two Cell Phone Jammer can be placed in each classroom, one in the front and one in the front. Due to the enhanced superposition of shielded signals, a better effect of 1+1>2 can be achieved. In addition, in order to ensure the shielding effect, a mobile phone signal jammer device can be installed every 10-20 meters in the corridor of the teaching building. In the future, it should be noted that the installation height of the mobile phone signal jammer is preferably 1.5-2 meters above the ground.
Many customers often call and say: I need a Blocking Gps On Cell Phone Or Tablet with a radius of 50 meters, an interval of 500 meters, and a radius of one kilometer, and I need to block the three networks of China Mobile, China Unicom and China Telecom. Is there a problem with the client's request? No problem, the specific interval requirements are also given, but can it be completed? The answer is: it is more difficult to implement. What will happen? The parameters of the mobile phone signal jammer are not all marked with their own shielding interval, just put a few more units according to this interval? In fact, the customer's request is not wrong, but they may not know that the shielding scheme of the mobile phone signal jammer is not a fixed value. This requires us to understand the working principle of mobile phone jammers: the signal jammer scans the low-end frequency of the channel to the high-end at a certain speed during operation. Such a scanning speed will cause garbled interference in the message signal received by the mobile phone, so that the mobile phone cannot detect the normal microwave signal data advertised by the base station. Under a certain scheme, the mobile phone cannot be connected to the base station, so as to achieve the purpose of shielding the mobile phone signal.
