Signal Blocker

A conference room with a relatively small area is a conference room mobile phone signal shielding device that can choose an external antenna. This kind of shielding device with an external antenna is often cheaper and relatively economical. Let's not talk about the quality and craftsmanship for the time being. The antennas of some conference room cell phone signal jammers with external antennas are even of different lengths, which will definitely affect the overall aesthetics of the conference room environment, and the heat dissipation of some conference room cell phone signal jammers The fan is exposed outside. With the rotation of the cooling fan, some noise will also be generated. The noise will seriously 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, so that the conference room phone The signal 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 conference room mobile phone signal jammer.

When choosing a conference room mobile phone signal jammer with built-in antenna, the antenna is completely invisible from the outside of the shielding device, so that the antenna is not exposed, and the antenna is built-in, which is also a kind of protection for the antenna, which can avoid the inconvenience during the transfer process. Be careful to bump into the antenna, it is easy to knock the antenna off, so the machine can no longer be used and needs to be returned to the factory for repair. Continued use will cause the radio frequency module inside the conference room cell phone signal jammer to burn out. If the mobile phone signal shielding device with built-in antenna needs to be transferred, it is very convenient. You can directly grab the groove handle on the back of the machine, which is simple and convenient. Even if there is a slight bump, the internal antenna will not fall off, which can ensure the mobile phone Normal use of signal jammers.

In prisons, detention centers and other supervision places, other communication tools such as mobile phones are prohibited from being brought into the supervision area. It brings great harm to the management, safety and development of the supervision site. Because of this, the installation of cell phone signal blocking systems in prisons and other supervised places has reached a very necessary level. Compared with ordinary mobile phone jammers, the mobile phone shielding system has relatively prominent features, mainly in the following aspects

1. The mobile phone signal shielding system can be centrally controlled and managed through software The entire mobile phone shielding system is controlled and managed by a set of software, and managers can see the shielding status in the monitoring area at a glance through the unit structure diagram (equivalent to the unit electronic map) on the main control software. This brings greater convenience to the management of the mobile phone signal jammers installed in the supervision site, and saves a lot of management time. Handheld Portable GPS Jammer Blocks GSM 3G 4G WiFi Frequency 2. The mobile phone signal shielding system can freely group mobile phone jammers, fully open, fully close, switch in groups (by building, by area), and switch on a point-to-point basis. In this way, the device manager can sit at the computer and open the software to realize the remote switch of all cell phone signal jammer, and can also directly see whether the cell phone jammer is turned on on the software. 3. Managers can manually operate the cell phone shielding system or set up to automatically query the working status of each cell phone jammer. For faulty or damaged cell phone signal jammers, the cell phone shielding system can immediately find out, greatly reducing the daily inspection of managers. time and speed. 4. Managers can adjust the transmission power of each module of each cell phone jammer by operating the cell phone signal shielding system, that is, they can adjust the shielding range of the cell phone jammer, and can shield the cell phone jammer installed around the prison wall. The scope should be controlled within the fence as much as possible, and will not affect the normal communication of the people outside the prison area. So as to avoid unnecessary trouble.

If you want to know whether the cell phone signal jammer will interfere with the ZigBee signal, you must first understand what the ZigBee signal is. Zigbee technology is a wireless communication technology applied in short distance and low speed. Zigbee was also called "HomeRF Lite" and "FireFly" technology in the past, and they are collectively called Zigbee technology. It is mainly used for data transmission between various electronic devices with short distance, low power consumption and low transmission rate, as well as typical applications with periodic data, intermittent data and low response time data transmission.
