Nowadays, many primary and middle school students have a mobile phone, some are addicted to games, some are addicted to novels, etc., which is more dangerous for school exams. Baidu has all the answers. It's a violation of the exam if everyone on the exam copied their phone. purpose and meaning! In the face of Ciggeratte Outlit Cell Phone Blocker we need to look at it rationally and scientifically. The working principle of the mobile phone signal jammer is to send out a specific signal to wake up or interfere with the signal between the mobile phone and the base station, so that the mobile phone has no signal or cannot find network services, and the information sent and received by the text phone will also become garbled. Therefore, the original message cannot be recognized. In fact, cell phone jammer generally does not affect the signal of the base station, so don't worry, no one will want to interfere with other people's signals.
Simply put, the frequency of the Ciggeratte Outlit Cell Phone Blocker declaration interferes with the frequency of the cell phone reception tower. Cell phone jammers and cell towers are destined to be a race to the connections. If the jammer's transmit power is less than the tower in the environment at the time, the tower will transmit to the phone. channel power, cell phone jammers cannot be shielded. Only the power of the signal blocker is greater than the power transmitted by the signal tower to the mobile phone to effectively block. Therefore, any mobile phone jammer will show different shielding intervals when used in different signal environments, and China Mobile, China Unicom and China Telecom will also be different. Because the density of the signal towers built by the three operators, the direction of the signal towers, and the power of the signal towers are all different. It can't be the same.
