Cell Phone Blocker Commercial Prisons

The space environment of the prison area is relatively complex, unlike conference rooms, courts, examination rooms, etc., which are just a single room. Therefore, when installing Cell Phone Blocker Commercial Prisons , a prison area or several prison areas or even the entire prison should be comprehensively considered, and the interference signals should be evenly distributed. It is necessary to keep the places that need communication, and the places that do not need communication can not be communicated all year round, so try to choose The antenna is a high-power mobile phone signal jammer that works in a directional way, instead of a small-power jammer with a large number of simple machines, which is not only low-efficiency, large-scale engineering, high radiation and power consumption, but also very troublesome to maintain. to the destruction of criminals. The prison is a place where the cell phone signal jammer is turned on continuously for many years. If you choose an ordinary analog cell phone jammer, it will inevitably affect the uplink communication of the base station, resulting in strong interference in large areas of neighboring cells, factories and units. Then complained to the local radio management department, and finally the equipment was banned from running or even investigated, so the prison would not be worth the loss. Therefore, it is necessary to choose a digital mobile phone signal jammer that adopts time division synchronization technology. This kind of jammer can effectively select the downlink pilot time slot of the signal for shielding, and will not interfere with the uplink communication of the base station. Moreover, this type of mobile phone signal jammer can accurately shield frequency points and bandwidth, and control spurious, which provides convenience for opening the police communication function in the future.

Is there a communication base station around the school? When we are doing engineering construction, we often see customers tell everyone that Cell Phone Blocker Commercial Prisons will have practical effects. 2G3G can be shielded, in other words, the data signal of voice calls can be shielded, but the data signal of 4G cannot be shielded. In fact, the electric power of each cell phone jammer is different. Generally, the output power of 4G1 and 4G2 is around 2W, in other words, 33db. If there is a communication base station within 200 meters, such a device, that is, 4G data signal shielding. It will also happen, and customer feedback will have actual results. The data signal (234G) of the voice call is alternatively shielded. If you only shield 23G or only 34G, this can be changed before shipment. In addition, there are 2.4GWIFI, 5.8GWIFI, VHF, UHF and other frequency bands. How to understand it? That is, if you only want to block voice calls or Wi-Fi, the manufacturer can mainly push 2G3G on the server, and the cost will come out.
