The higher the power, the better the effect of a frequency interference instrument. Factors such as electronic components, working mode, indoor and outdoor environment need to be considered. The interference effect is affected by signal strength, quality, direction, distance, and transmission characteristics. Accurate construction requires early research and testing, and later tracking and supplementation to ensure strict interference effects. The frequency interference meter is actually not like this. It's not that the higher the emission power of the jammer, the better. The power of frequency interference meters also has a certain level of safety power. Some customers have expressed why most merchants have poor interference effects on their machines when the signal source is very close, while some merchants have good interference effects. When the signal source is very close, the interference effect is good and the power is relatively high, because the electronic components used in the interference instrument are different and the debugging is different.

The interference effect of using a frequency jammer has some impact on the output power of the jammer and the performance of antenna interference. Nowadays, mobile phones are all digital signals, and the anti-interference ability of digital signals is very strong. The selection of electronic components and technical workmanship of frequency jammers determine the effectiveness of mobile phone interference. The synthesis, attenuation, and reflection analysis of indoor mobile phone signals and interference signals are very complex. Before interference, the strength and quality of mobile phone signals in the local space have a significant impact on the interference, and different mobile phones have different effects. Generally, mobile phones with strong weak signal reception capabilities may not have good anti-interference effects. The direction and distance of the signal source and the direction of the mobile phone interference area also affect the interference effect.
