How To Detect Cell Phone Jammer In Nyc
The key to mobile phone signal jammers is for various examination venues, colleges, gas stations, main churches, courts, public libraries, international conference centers (rooms), cinemas, hospital outpatient clinics, government departments, financial industries, prison cells, public security agencies, Places where the use of mobile phones is strictly prohibited in areas such as national defense centers. According to statistics, the How To Detect Cell Phone Jammer In Nyc on the sales market today can limit the data signal that is 500M meters away from the transmission tower and 20 meters in half. The shielded semi-warp adjustable type, it only shields the data signal, and does not cause harm to other electronic products. cell phone jammer Save electromagnetic energy, the output power is 20W-480w.
When the mobile phone works, it is in the relative frequency range. The mobile phone and the communication base station are connected according to electromagnetic waves, and the data information and sound transmission are carried out with the relative serial port baud rate and deployment method. For the basic principle of this kind of communication, How To Detect Cell Phone Jammer In Nyc In the whole process of work, go to the high-end scanner at the low and middle frequency of the wireless channel at a relative rate. The scanner rate can generate error code interference in the message format data signal received by the mobile phone, and the mobile phone cannot check all normal data information transmitted from the communication base station, so that the mobile phone cannot establish a connection with the communication base station. The main manifestations on the mobile phone are the search network, poor signal, no service system, etc. At present, the common mobile phone signal jammers on the market have effective frequencies: 869~894MHz; 825~960MHz; 1805~1880MHz and 1900~1990MHz, etc. The effective frequency bands are CDMA800, GSM900, DCS1800, and PCS1900. It can manipulate a range of 40 meters in diameter, use DC-DCSPWM to enter the working voltage, and 5V output voltage.
