The effective interference range of wireless frequency jammer mainly depends on the following points:

1. Its own power. Because the interference range of the jammer is related to the power, the machine with appropriate power shall be purchased to meet the demand. For example, for a low-power wireless frequency jammer within 30W, the interference range is about 10-60m.

2. Distance from the base station. Some wireless frequency jammers have little interference effect on mobile phones because there are base stations nearby.

3. Whether there is any shelter around. The interference signal emitted by the jammer will attenuate to varying degrees after passing through the shelter, which needs to be avoided.

Based on the above, the interference range of wireless frequency jammer is affected by many factors.
