In what kind of environment can cell phone signal jammers be installed to achieve better results? Why do sometimes installed signal jammers not work, or have poor results? In fact, this boils down to the surrounding environment where you use the signal jammer. In terms of installation technology, the following factors must be considered when using signal jammers:

The comprehensive factors for indoor shielding include:

1. Consider the lateral application field space in the area that needs to be shielded;

2. The floor height of the shielding area calculated from the air or the vertical height perpendicular to the ground;

3. What needs to be considered is the blocking effect of house decoration materials and building materials themselves;

4. What needs to be considered is whether source signal enhancement measures or secondary amplification have been adopted indoors;

5. What needs to be considered is the proportion of indoor metals and non-metals;

6. It is necessary to know whether the transmitting frequency of wireless devices already existing in the room will cause same-frequency mutual interference;

7. It is necessary to consider the ability of existing indoor precision instruments and equipment to resist inter-frequency interference and the safe distance;

8. What needs to be considered is the partition status and orientation of the windows, doors and windows of the house;

Comprehensive factors for outdoor shielding:

1. Before installing equipment in open spaces and non-open spaces, you should consider:

1. When the repeater emits strong electromagnetic wave signals horizontally and vertically, it will affect the shielding device;

2. The influence of the signal jammer for sale on the repeater signal during the interval time and the antenna selection can be affected by the antenna selection;

4. Separating walls and debris block the repeater from transmitting signals;

5. The blocking effect of stray objects and non-moving solid barriers on the radio wave of the shielder;
