Background of mobile phone jammers: We are forbidden in all kinds of examination rooms, schools, gas stations, churches, courts, libraries, conference centers (rooms), theaters, hospitals, governments, finance, prisons, public security, military power and other occasions. Those who use mobile phones are prohibited from using mobile phones in the above occasions. However, in the above occasions, the mobile phone will be turned on and brought in if you are not paying attention. Therefore, a technology is urgently needed to shield the mobile phone without affecting the use of other electronic products. , Literature Review On Cell Phone Jammer Came into being. The principle of the mobile phone jammer is within a certain frequency range, the mobile phone and the base station are connected by radio waves, and the data and sound transmission is completed with a certain baud rate and modulation method. In view of the above-mentioned communication principle, the mobile phone jammer scans from the low-end frequency of the forward channel to the high-end at a certain speed during operation. This scanning speed can cause garbled interference in the message signal received by the mobile phone, and the mobile phone cannot detect the normal data sent from the base station, so that the mobile phone cannot establish a connection with the base station. The mobile phone is manifested as a search network, no signal, no service system and other phenomena. Eventually, the mobile phone has no signal and cannot receive text messages or calls. cell phone jammer
Product performance of mobile phone signal jammer: six-channel cross-shielding to achieve the best shielding effect. The shielding includes GSM, CDMA, DCS, PHS, TD-SCDMA, CDMA2000, WCDMA, 4G and effective segmentation, which only interferes with the downlink and does not cause the base station. Interference: The power indicator on the fuselage is so that the height of the suspension is higher than the line of sight range, and the shielding work can also be understood through the indicator below. Imported chips to ensure quality and stability; built-in power supply to prevent malicious damage by criminals and ensure machine life; dual-channel metal industrial switching power supply, truly realize uninterrupted and sustainable work; low-power machines, green and safe, and do not pose a threat to health. Literature Review On Cell Phone Jammer Application case: Daxing Fifth Middle School Examination Center, completed the supply of mobile phone signal jammers, and escorted the fair and just order of the examination room; Zhejiang Textile Printing and Dyeing Factory Workshop, completed the supply of high-power mobile phone jammers; Yijinhuoluo Detention Center, completed The mobile phone jammer was supplied, and the mobile phone jammer project in the detention center was completed, and the system worked well; Dingbian County Radio and TV University teaching and guidance station purchased our mobile phone jammer, successfully completed the construction of the mobile phone jammer system, and the system worked well; Wenshan Prefecture, Yunnan Province The Admissions Office of Guanxian Education Bureau purchased our mobile phone jammer and successfully completed the construction of the mobile phone jammer system, and the system worked well; the Education Bureau of Hongsibao District, Wuzhong City, Ningxia purchased our mobile phone jammer, and the system worked well.
