The cell phone signal jammer belongs to the same frequency amplifying device, which refers to a wireless transmission and transmission device that plays a signal enhancement role in wireless communication transmission. The basic function of the mobile phone signal amplifier is the radio frequency signal power booster. In the downlink, the mobile phone signal amplifier picks up the signal from the existing coverage area of ​​the donor antenna. The signal outside the band pass is completely isolated by the band pass filter, and the filtered The signal is amplified by the power amplifier, and then transmitted to the area to be covered again. In the uplink path, the signal of the mobile phone in the coverage area is processed by the uplink amplification link in the same working mode, and then transmitted to the corresponding base station to achieve Signal transmission between base station and mobile phone.

The Bathinda police proposed to equip their traffic police with car cameras that support WiFi. The police have even begun to build a control room and soon issued an order for 100 such cameras, which will cost them 3.2 million rupees.

Since the device has WiFi enabled, the recorded clips will be streamed to the main control room in real time, while the unedited records will be used as evidence of the dispute. These cameras are used to collect evidence and record conversations with the public when challenges are issued.

SSP also said it will buy high-quality cameras. "In addition, we are planning to connect the wifi signal jammer to the device so that the driver cannot get rid of the phone without paying a fee.

The use of mobile phone signal jammer is one of the necessary means to achieve the goal of "small capacity and large coverage", mainly because the use of mobile phone signal amplifiers is to ensure network coverage without increasing the number of base stations, and its cost is much lower than that of a microcellular system with the same effect. Cell phone signal amplifiers are the preferred solution for expanding the coverage of communication networks. Compared with the base station, it has the advantages of simple structure, less investment and convenient installation. It can be widely used in shopping malls, hotels, airports, docks, stations, stadiums, entertainment halls, subways, tunnels, highways, islands and other blind areas and weak areas that are difficult to cover, improve communication quality, and solve problems such as dropped calls.
