Under what environment can the mobile phone signal jammer be installed and the effect is better, why sometimes the mobile phone signal jammer installed does not have the effect, or the effect is very poor? In fact, this is due to the environment around you using the mobile phone signal jammer of. In terms of installation technology for mobile phone signal shielding, the following elements must be considered:
1. Comprehensive factors when indoor shielding:
1. Consider the horizontal product of the application field in the area to be shielded;
2. Consider the floor height of the shielded area or the vertical vertical height from the air;
3. It is necessary to think about the house decoration materials and the shielding effect of the building materials themselves;
4. It is necessary to think about whether source signal enhancement measures or secondary amplification have been adopted indoors;
5. Need to think about the proportion of indoor metal and non-metal;
6. It is necessary to consider whether the transmitting frequency of the existing wireless equipment in the room can cause mutual interference of the same frequency;
7. It is necessary to think about the ability of anti-interference interference of the existing fine instrument equipment in the room and the safety interval;
8. It is necessary to consider the isolation and orientation of windows, doors and windows of houses.
2. Comprehensive factors for outdoor shielding:
1. You need to think about the installation of open and non-empty venues:
2. The ability of the repeater to affect the shield when transmitting strong electromagnetic signals horizontally and vertically;
3. The influence of the shielding device on the signal of the repeater in the interval and antenna selection direction can be matched with the antenna selection;
4. The ability of the isolation wall and debris to block the signal transmitted by the repeater;
5. The ability of stray objects and non-moving solid barriers to block the radio waves of the shield;
6. Analysis of the resistance and feasibility of avoiding large-scale strong radio magnetic fields such as interval TV transmission towers, military radio transmission towers, and aircraft navigation systems;
Various environmental factors will cause the effect of mobile phone signal jammers to become weaker. Moreover, today's mobile phone signal jammers all use technology that does not affect the uplink (base station), which will not affect the use of mobile phones by peripheral personnel, but it also improves the environmental requirements of mobile phone signal jammers.
