Classroom Cell Phone Signal Jammer
However, is this Classroom Cell Phone Signal Jammer really that effective? The entire frequency band of electromagnetic waves ranges from the smallest a few Hz to the largest hundreds of GHz, and each segment may be used as a communication signal, but except for a small number of very professional equipment, ordinary signal jammers Both "voices are not loud enough" and "five tones are not complete". A signal jammer can only shield a small part of the frequency bands, and communication tools can use unshielded frequency bands for communication. Of course, all the 2G, 3G, and 4G mobile phone services of several domestic communication companies are concentrated in a few small frequency bands. The signal jammer in the examination room can still concentrate on these frequency bands. signal jammer When working, it will send out chaotic electromagnetic waves from low frequency to high frequency in various frequency bands, which will interfere with the connection between the mobile phone and the base station. Therefore, I heard that a very witty child has successfully completed the arduous task of delivering answers using the wifi name.
Nowadays, some specialized signal jammers can be shielded specifically for one or a type of signal, such as Classroom Cell Phone Signal Jammer , which is a device specially used for shielding mobile phone signals, which has no effect on other equipment signals at that time. of. The second is that the signal jammer only has a shielding effect in a certain range. This range is formulated according to the specific specifications of the signal jammer. Therefore, the use of the signal jammer in a specific place will not affect the surrounding signal base stations. normal work. In addition, when the signal shielding instrument is used, it will not produce harmful radiation to the human body, so it can be used boldly and safely. When using a signal jammer, first find a place to put it. When installing a signal jammer, you must have a basic understanding of its shielding range, so that the shielding range meets the needs of use, and try to avoid letting the signal jammer affect other equipment. Normal use. After the signal jammer is installed, the power is turned on and the signal jammer starts to work normally. Generally speaking, the signal jammer is still very convenient to use, coupled with its portable characteristics, so it now has a very wide range of application markets.
