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 controls, wireless routers used at home, etc. These devices use wireless signals to transmit, and then achieve our desired purpose and improve people's quality of life. 

Of course, the popularity of wireless signals will also be used by some criminals to achieve their illegal activities. At this time, the wireless jammer will come on the stage. As we all know, the interference range of the wireless jammer is limited. What are the factors that affect the interference effect of the wireless jammer? Next, we will introduce in detail:

1. The interference effect of the so-called wireless jammer is whether there is a blind area in the interference area. There may be a base station or wireless signal amplification system near some examination halls. These two devices have the greatest impact on the interference range of the wireless jammer. In order to achieve a good interference effect, more powerful equipment may be required to deal with it, and the cost will increase accordingly.

2. The service time of the wireless jammer without failure. If the expected stable operation time of the equipment in design is one year, but in actual use, it can reach two years or more, then the cost performance ratio is very high.

3. The suppression of external interference of radio jammer. If the suppression of external interference can be excellent, not only the wireless signal in the area to be interfered is completely interfered, but also the external interference can be ignored. This will reduce a lot of external disputes. The jammer is easy to use, and also reduce the time users should spend on interference disputes.
