The basic principle of the mobile phone (wireless communication) is as follows: within a certain frequency range, the mobile phone and the communication base station are connected according to electromagnetic waves, and data information and sound transmission are carried out at a certain serial port baud rate and deployment method. For the above basic communication principles, the Cell Phone Jammer Build Your Own will go to the high-end scanner at a certain rate at a certain rate during the whole working process of the wireless channel. The scanner rate can produce error codes in the message format data signal received by the mobile phone, and the mobile phone cannot check all normal data information transmitted from the communication base station, so that the mobile phone cannot establish a connection with the communication base station. The main manifestations on the mobile phone are the search network, poor signal, no service system, etc. Originally used mobile phone jammers with older models and specifications only shielded the old number segments of PHS, China Mobile, and China Unicom, like the newly listed Telecom Tianyi 186. China Unicom's Wo number segment and its mobile TD-SCDMA number segment cannot be blocked! In short, the beginning of 1315 cell phone jammer China Unicom and mobile number segments and all PHS number segments can all be blocked!
Since the original Cell Phone Jammer Build Your Own principle is to shield the mobile phone according to the signal on the mobile phone that affects the specific stock band, only need to change the reception and transmission frequency on the mobile phone to avoid being shielded, and the mobile phone jammer can only shield the data of 900---1800MHZ. The receiving and sending frequency on the mobile phone is 850—1900MHZ is much higher than the shielding range of the mobile phone jammer. Therefore, you only need to adjust the receiving and sending frequency of the mobile phone to a larger value in the mobile phone settings to receive the data signal normally. NS. This method has higher regulations on mobile phones and the natural environment, but the actual effect is best to be the most invisible. The prerequisite is that the mobile phone must have a Wi-Fi wireless network function. There must be a working WWi-Fi network around the A high is basically impossible). After finding and successfully connecting to a usable wifi network with a mobile phone, even if there is no signal on the mobile phone, it can still be online without changing the total traffic. At this time, if you want to find an answer that is not easy, you can search on Baidu. If you want to send an answer, you can use QQ. You can play whatever you want. A super way. Students with a suitable distance of no more than 50 meters can transmit their answers, and they can test themselves in the two neighboring classrooms. Use Bluetooth software similar to the mobile phone Bluetooth network hacker on the mobile phone, and then both parties turn on the mobile phone’s Bluetooth so that the visibility is fully opened. In the mobile phone software options, there is a mandatory option to push information based on the mobile phone’s Bluetooth, and type the answer. Coming in for mandatory push, all Bluetooth phones that are visible from this will receive the answer, and one person will push it to share in the class. The above method is the method I thought of after a few days of thinking and thinking. It is given to all the students who are annoyed by the shielding of data signals in an ordinary high school. I hope that the application of the above method will enable students to learn from the super abnormal colleges. Liberate, get relaxed and happy!
