With the rapid development of wireless technology, the devices that use wireless signal transmission are also closer to life, including our most commonly used mobile phones, walkie-talkies, car remote control, wireless routers for home use, etc. These devices use wireless signals for transmission, and then achieve the purpose we want to improve people's quality of life. Of course, the popularity of wireless signals will also be used by some criminals to realize their illegal activities. At this time, the wireless signal jammer will be on the stage. As we all know, the wireless signal jammer has limited interference range. What are the factors that affect the jamming effect of the wireless signal jammer? Next, we will introduce in detail:

1. The interference effect of the so-called wireless signal jammer is whether there is a blind area in the interference area. There may be base stations or cell phone signal amplification systems near some examination rooms. These two devices have the greatest impact on the interference range of the wireless signal jammer. In order to make the jammer achieve a good jamming effect, it may need equipment with higher power to cope with it. At this time, the cost will also increase a lot.

2. The trouble-free service time of the wireless signal jammer. If the expected stable operation time of the equipment is one year at the time of design, but it can reach two years or more in actual use, then the cost performance ratio is extremely high.

3. External interference suppression of wireless signal jammer. If the suppression of external interference can be done very well, not only the digital signal in the area to be interfered is completely interfered, but also the external interference can be ignored, which will reduce a lot of external disputes. The use of the jammer is convenient, and also reduce the time users should spend on interference disputes.
