Does Blocking Call Eat Up Storage On Cell Phones Interfere With Mobile Networks
The interference power of the mobile phone jammer is fixed, and the shielding radius of the unobstructed space is determined by the path attenuation and the signal level of the receiving base station. In order to realize the interference of the mobile phone signal jammer to the mobile network, it must be ensured that the signal field strength sent by Does Blocking Call Eat Up Storage On Cell Phones is stronger than the field strength of the mobile signal in the interference area. The closer the interference location is to the base station, the stronger the field strength and the smaller the effective interference area. On the contrary, The farther the interference site is from the base station, the weaker the field strength and the larger the effective interference area. It can be seen that within a certain transmission power, the interference range depends on the field strength in the interference area. No matter how powerful the mobile phone jammer is, as long as the transmission power is a fixed value, as the distance increases, the interference signal strength will gradually attenuate, thus Lose the ability to interfere. The table below provides a comparison table of distance and path attenuation. Then, the theoretical coverage radius with reference value can be determined by the output channel power of the masker, the signal level of the base station, and the gain of the coverage line.
Some candidates brought their mobile phones into the examination room to take test papers and seek answers. In addition, there are screenshots of relevant online transmissions that also show that someone disclosed the answers to the nine types of single-stroke exams in advance. The staff of the Hebei Provincial Education Examination Institute said that the investigation was underway. Some students who participated in the single-admission test left a message: Even if we are not studying hard in the cold window, we are preparing for the test seriously. If someone cheats and easily gets the question, is it worth everyone's hard work? In fact, this situation is likely to be due to the insufficient work done in the examination room to prevent technological cheating. You must know that during the college entrance examination every year, the major examination rooms are in full preparation. Whether it is to detect various communication tools through metal detectors when entering the examination room, or to open the Does Blocking Call Eat Up Storage On Cell Phones in the examination room throughout the whole process, they are all necessary equipment for the examination center. The purpose is to prevent candidates from using mobile phones. and other communication tools to cheat. However, some higher vocational colleges may not pay enough attention to preventing cheating by means of technology, or there are omissions in preventing cheating through technology, so that the mobile phones in the examination room can communicate with the Internet normally, and the cheating candidates take advantage of them. Therefore, whether it is a college entrance examination room or a single-admission examination room of a higher vocational college, in the face of technological cheating, we must not be careless, especially when using cell phone jammer , we must not have omissions.
