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.

5G signals usually use some of the frequency bands of 4G signals. Of course, 5G also has millimeter wave base station equipment, but most countries do not use millimeter wave equipment. Because of the short distance of millimeter waves, the construction of base stations is difficult, the cost is high, and the economy is poor.

How do we choose a 5G mobile phone jammer?

First of all, most 5G jammer on the market do not cover millimeter waves. Because millimeter waves are difficult to interfere, and most countries do not apply such bands. There are also relatively few millimeter-wave base stations.

At this time, we have to look at our local signal coverage.

—————————————–

600 (n71) / 700 (n28) MHz,

2.5 (n41) /3.5 (n78) /4.5 (n79)

—————————————–

5G600: 617-685MHz

4G(LTE): 700-825MHz

4G(WIMAX)/5G: 2500-2690MHz

5G3400: 3400-3600MHz

5G3600: 3600-3900MHz (n78)

Generally speaking, these frequency bands are commonly used in 5G.

So currently jammers.store supports most of the 5G signal shielding, and what is missing is the millimeter wave shielding.
