But we realized that if students were using their phones there were a lot of negative issues, and that was a big problem! More and more teachers are annoyed by this and want to find a solution to the problem. What if there was a device that could block the noise? What if there is a device that can keep student phones from working? In fact, with a portable cell phone jammer, the problem can be easily solved.

When the WiFi isolator is working, if the transmission power is too large due to the improper setting, in a small-scale conference room, classroom and other confined spaces, the electromagnetic waves are superimposed in the narrow space, and the electromagnetic waves will pass through the walls, ceilings, and floors that are originally separated from the outside for many times.

Some candidates even Headache symptoms occur. There are various indications that if the transmission power of the WiFi jammer is too large, it will seriously affect the normal thinking of candidates in the examination room. When you really need to use a WiFi jammer, try to use a low-power WiFi jammer. If one can solve the problem, don't set up multiple ones. The lower the installation position, the better. Do not hang it on top of people's heads, which is very detrimental to human health.

At present, China Unicom and China Mobile, including China Telecom, have already launched their own 4G frequency bands. Some GPS blocker manufacturers can block a frequency band that you can block called 4G. Very irresponsible to consumers. We know that every high-tech product was invented because people had this need, like a cell phone, because it was easier for those who needed it to communicate than before, including 4g phones that are now commonplace. But the 4g signal that many people are using these days and people who suffer from loud phone calls complain and make sure it's quiet in places like conference rooms, classrooms and late at night where people need to sleep a GPS jammer is a must for people.
