Afraid of incomplete shielding? The signal environment is complex, afraid of insufficient budget? Afraid of being destroyed, the machine life is short? Just want to block one kind of signal, afraid of affecting other frequency bands? Afraid of installing a shielding device and being discovered by others? Afraid that the shield is too ugly to affect the indoor environment?
The wifi signal jammer is divided into the following situations according to the shielding range and the port data used:
The first one: How many meters can the shielder shield?
It is not only related to its own transmission power, but also to the distance of the base station in the use environment (the base station is not limited to the large transmission tower built on the ground, but also the signal amplification antenna on the roof and the signal amplification done in some buildings. Distribution), and another important factor is the obstacle, if it is a metal material, it will be blocked directly; if it is a solid wall of reinforced concrete, it will attenuate at least 10 times after penetration.
The second: the strength of the magnetic field signal.
When the magnetic field is weak, install one in 2.5 classrooms. If there are 10 classrooms in a row, install 3 in the aisle. When the magnetic field is strong, there is a base station within 500 meters, a base station within 300 meters, a base station within 200 meters, and a base station within 100 meters. Base station, there is a base station on the roof, it can only depend on the situation, the stronger the magnetic field, the more points that need to install the wifi signal jammer.
