The conference room signal jammer used in the conference room with a small area is a conference room signal jammer that can choose an external antenna. This external antenna signal jammer is composed of a power adapter, a jammer host and an antenna. Because there is no shell cost, the price will be relatively lower. Let's put aside the quality and craftsmanship for the time being. Some shield antennas are even of different lengths, which will definitely affect the overall aesthetics of the conference room environment, and it will appear very awkward. In addition, the heat dissipation of some shielding devices is not designed through the air duct. With the rotation of the cooling fan, some noise will be generated, which will affect the order of the meeting room in the conference room. If the meeting time is within an hour, the cooling fan can be disconnected. The conference room mobile phone jammer will not generate noise when it is turned on. If the meeting time exceeds one hour, it is recommended to use a low-noise jammer.

When choosing a conference room mobile phone signal jammer with built-in antenna, the antenna is completely invisible from the appearance of the shielding device. The jammer itself forms a whole, and the built-in antenna is also a kind of protection for the antenna, which can avoid transferring In the process, if you accidentally bump into the antenna, it is easy to break the connector between the antenna and the host. At this time, the shield can no longer be used and needs to be returned to the factory for repair. If you continue to use it, it will cause the radio frequency module inside the conference room signal jammer to burn out. If the signal shielding device with built-in antenna needs to be transferred, it is very convenient. You can directly grasp the groove handle on the back of the machine. It is simple and convenient. normal use of the device.

The police frequency jammer purchased by the customer earlier did not have the operator's 5G frequency jamming module. With the gradual popularization of 5G signals, the original police jammers without 5G frequencies cannot shield and interfere with 5G signals, so it is necessary to upgrade the frequency of 5G signals to the jammers in order to form shielding interference for 5G frequency signals. .

Jammer Frequency

According to the operator's 5G signal frequency division promulgated by the Ministry of Industry and Information Technology, and the original operator's 4G signal frequency, the 700M shared by radio and television and China Mobile, the 3.4G-3.6G frequency of China Telecom and China Unicom, and the 2555-2655 frequency of the original 4G mobile phone are spread spectrum To 2515-2675M, that is to say, to upgrade the 5G shielding module of the police frequency signal jammer, 2-3 modules need to be added, and the mobile 2.6G module needs to be spread spectrum. The shielding interference of 5G signals can be realized. Some friends will ask, why hasn't the frequency of 4800-4900M increased for mobile 5G? This is because the current frequency of 4.8G-4.9G has not been fully spread out. It is necessary to judge whether the police jammer needs to increase the jamming module of this frequency band according to different use sites.

Recently, many customers have been inquiring about how to choose a mobile phone jammer in different application scenarios, in which scenarios can high-power devices be selected, and in which scenarios should low-power devices be selected, this problem has been plaguing customers, and I will introduce to you next. In different application scenarios, you should choose a high-power machine or a low-power machine.
