Regarding the wireless signal jammer, it is a product used for communication supervision. It is used to supervise the seriousness and quietness of examination rooms, prisons, detention centers, etc., and to ensure the fairness and impartiality of examinations. Now the high school entrance examination, college entrance examination or usual mock examination. Most of the wireless wifi signal jammer will be installed to interfere with the signal, so should you choose high-power or low-power wireless signal jammers when purchasing, what is the difference between them?
When buying a wireless signal jammer, you must first know where to use it. If it is used indoors, such as the examination room, conference room, office, etc., you can use a low-power model. If it is an outdoor open area, you need to use a high-power model. Wireless signal jammers can achieve effective shielding distance.
In terms of appearance, wireless wifi signal jammers can be divided into external antennas and built-in antennas. Generally speaking, external antennas are usually used for high-power machines, while built-in antennas are mostly prepared for low-power machines. The wireless signal jammer antenna is external and extends outward, so it occupies a larger space than the built-in antenna, but also because of the outwardly extending antenna, the shielding effect of the external antenna is more stable.
In terms of shielding range, the examination room generally uses more low-power wireless wifi bluetooth jammer, one can be installed in a classroom, and the shielding range is about 200 square meters; while for high-power wireless signal jammers, the shielding distance can reach 300- 400 meters (actually determined according to the local field strength)
In general, the high-power wireless wifi frequency jammer is a drag box design, and the volume is very large. The smaller one is the desktop low-power machine, which is relatively small in size and easy to carry.
