Why does the desk top jammer in the examination room choose the built-in antenna?
With the continuous development of communication technology, the mobile network has also been upgraded several times, from the initial 2G mobile phone network to the current 3G, 4G to 5g mobile phone signal network. At the same time, the desktop jammer has also undergone continuous upgrading.
Desktop jammers are mainly used in school examinations, college entrance examinations and some venues where mobile phones and other communication equipment are prohibited. With the increase of communication network frequency band, the jammers have changed from the original 4-channel antenna to 8-channel antenna or even 12 multi-channel antenna, until now the built-in antenna desk jammer.
First, the built-in antenna jammer has a beautiful appearance, which meets the modern aesthetic conditions, and eliminates the need to screw on the antenna one by one during use.
Second, the built-in desktop jammer is more green and safe. After the external metal shell jammer has been turned on for a long time, the machine will produce a high temperature of 50-60 degrees, which also has certain security risks. The built-in antenna jammer has a built-in Xunhua heat dissipation system, which solves this problem well.
Third, it is easier to carry and has better practicability and lower repair rate, because the old external antenna desktop jammer often has the loss or damage of the antenna, while the built-in antenna has both the transmitting antenna and the power supply built into the plastic shell, so it is very simple and convenient to use and carry, and it only needs to turn on the power when necessary, After use, there is no need to disassemble the antenna, just turn off the power, so it greatly improves the efficiency and reduces the later maintenance cost.
