With the popularity of mobile phones, the demand for cell phone jammer in various meetings and examinations has greatly increased, so mobile phones in mobile phone jammers naturally have a broad market. However, extremely
Most customers do not have enough understanding of the mobile phone jammers of mobile phones, and often choose high-power shielding unilaterally in order to achieve good results, which causes many hidden dangers. Then when installing
What issues should be paid attention to?
Misunderstanding 1: The more power the better
1. Inaccurate frequency output of the host computer, waste of power, frequency drift, too wide bandwidth, interference to the base station
2. The shielding efficiency of the simple scanning power suppression method is not high, and the radiation is large
3. Exaggerated publicity, power is wrongly marked, and nominal power loses its reference value
4. Hard power is better than finding good methods and skills. Power is the foundation, technology is the key
Misunderstanding 2: Using directional antennas can avoid interference
1. There is a certain transmitted signal strength outside the direction angle of the directional antenna, it is not completely directional, but much lower than the main lobe
2. The reflection of the building will still cause external interference
3. The frequency drift of the host seriously affects the base station and causes external interference
4. There must be full-time shielding interference
Misunderstanding 3: High-power devices have more radiation, and low-power devices have less radiation
1. Outdoor antennas are used for high power and have the characteristics of long working distance, large shielding range, uniform shielding signal, and minimal radiation.
2. If the low-power equipment does not use multiple antennas for long-distance shielding, but is arranged in a centralized manner or five antennas work together, the radiation power will be greater than 10 microwatts/square centimeter, and it will be short-range radiation.
