There are not a few people who have the same encounter with Mr. Du. We learned that there are tens of thousands of urban residents living around the campus, and their installation Cell Phone Jammer Project Report was affected by electromagnetic interference yesterday. "I also feel strange that I didn't receive a single call today. I used to have at least seven or eight consultation calls every day. If you don't say I don't know, the female boss of a water company station near Qingdao No. 15 Middle School told us. She said that she used to receive consultation calls for ordering water every day, usually more than 30, and at least 17 or 8 calls. But she didn't receive any of them yesterday. "Does this not delay her doing business? If it keeps doing this, I will have to install a landline myself, otherwise it will affect her business too much." The female boss said helplessly. Regarding this matter, a staff member of the municipal radio management committee unit said that in fact, the principle of smart phone signal jammer is very simple. cell phone jammer It is to use the frequency that it emits to electromagnetically interfere with the frequency of the mobile phone signal. To put it plainly, it is like "loudly overshadowed" when speaking.
If two people are chatting, how can they silence their voices? The answer is very simple, as long as the third party speaks in a louder voice. Smart Cell Phone Jammer Project Report is the third party. The staff member explained. , Smart phone signal jammer is essentially a radio technology FM transmitter. Regarding the working principle of this mobile phone jammer system, online merchants have such a professional description: The working principle of the smart phone system is in a certain frequency range, the smart phone and the base station are connected to each other by radio waves, at a certain baud rate And the modulation method completes the transmission of data information and sound. For this communication principle, the mobile phone jammer scans from the low-end frequency of the channel to the high-end at a certain rate. This scanning rate can cause garbled electromagnetic interference in the message data signal received by the mobile phone, so the smart phone cannot detect the normal data information sent from the base station, and cannot establish a connection with the base station.
