With the advent of 5G, our life seems to have changed a lot. Our school is now facing such a problem: we bought a batch of jammers to prevent students from cheating. However, I do n’t know if the 4G jammers I purchased work properly after 5G is popularized.

Your concerns are justified. When the 5G network arrives, the 4G signal jammer will not be able to shield the 5G frequency band. Because according to the signal principle, it is only downward compatible and not upward compatible. Therefore, once the 5G signal appears, the previously purchased interference equipment will no longer work, and we can achieve anti-cheating by purchasing a high-end 5G jammer.
