Answer this question

The mobile phone signal includes a 5G,4G,3G and 2G signal. How to choose this depends on the device you are targeting. If the area you are in has 5G network coverage and 5G devices are also the target, please choose a 5G jammer.

The WIFI signal is relatively simple, but some devices support a 5.8G signal. 5.8G devices are also relatively expensive. When the router does not use the 5.8G frequency band, you can choose a 2.4G WIFI jammer that covers the 2.4G signal.

According to the above analysis.

If you are a beginner, you only need to block the 4G and 2.4G WIFI signal.

Choose the device below.
