Range Of A Cell Phone Jammer
With the popularization of mobile phones, the demand for Range Of A Cell Phone Jammer in various conferences and exams has greatly increased, so mobile phone signal shielding naturally has a broad market. However, most users lack sufficient knowledge about mobile phone jammers. In order to achieve better results, one-sided selection ofmobile phone jammers will bring many hidden dangers. cell phone jammer The principle is to use broadband to send interference signals to interfere with the mobile phone's uplink signal to achieve the effect of shielding the mobile phone from working. Therefore, this itself is the birthplace of the signal. As a signal source, there will naturally be radiation.
According to the requirements of use, the transmit power of the existing Range Of A Cell Phone Jammer ranges from 1W to 480W. How big is this transmission power? In comparison, the larger transmission power of GSM mobile phones is 2W, and the GSM macro base station is generally 20W to 40W. The shielded emission power for general examinations and conferences is between 10W and 60W. Generally speaking, for general tests and small meetings, choosing a mobile phone jammer with a transmission power of 2W-10W can achieve good results. However, from our survey of large schools and important meeting places, many places often unilaterally pursueshielding. For example, in a school with more than 20 classrooms, each classroom is equipped with a mobile phone jammer device, and a transmission power of 30W is selected. In addition, after the exam, due to lack of attention to use, there are often a small number of screens that are not turned off in time and are sent out for several weeks. Especially in an elementary school, after the exam, the monitor has not been turned off for two consecutive weeks.
