In some basic parameters, in principle, the UAV countermeasure equipment can increase the transmission power to interfere with long-distance targets. Doing so may cause some unnecessary troubles, especially the interference to the GPS signal, which may affect the surrounding mobile phone base stations, nearby airports, etc., seriously interfere with the rights and interests of GPS users, and cause electromagnetic pollution and other problems.

At present, the Market Supervision Bureau has not specified the output power and quality standards of UAV countermeasure equipment. Some manufacturers arbitrarily increase the transmission power in order to improve the shielding effect of the UAV jammer equipment, which is not a rational behavior. Because the power output of the UAV countermeasure equipment is reduced as much as possible, the effect of antenna transmission is increased, the signal is more accurately focused on the target, and the countermeasure effect is improved. It is very necessary to establish technical standards for UAV countermeasures to prevent arbitrary increase in power and reduce the possibility of omnidirectional antenna radiation.

The method of adjusting measures to local conditions should be adopted to monitor the actual distance of the UAV's "black flight". Just blindly increasing the transmission power of the countermeasure equipment can only cause environmental pollution. For example, in the protection area of ​​500m*500m, it is sufficient to use UAV countermeasures with an interference distance greater than 1000m, and it is not necessary to install countermeasures with higher distances. Increasing the power of the UAV countermeasure equipment, although the interference distance is increased, the cost is relatively increased, and the pollution to the nearby environment is also increased.

Control the time when children play games: Use the full-band cell phone signal jammer device to reasonably control the WIFI network signal of mobile phones, so that students' mobile phones cannot play games online within a specific time. Reduce the conflict in the communication process between children and parents.

The school's classrooms and dormitories are equipped with full-band signal shielding devices, and the timer switch function is used to set the setting time to synchronize with the school's work and rest, so that the full-band signal shielding device can be turned on during class and rest time, the mobile phone signal is cut off, and the full-band signal shielding device is turned off during breaks. Frequency band signal shielding device, restore mobile phone signal, this type of full-band signal shielding device is very suitable for use in schools, the software automatically runs to control the switching time of the full-band signal shielding device, reduces the negligence of personnel control, and can reduce the number of personnel investment.
