Jammers, including wifi jammer, have been used by the military and law enforcement for years. They are an important tool for cutting off enemy communications or acquiring resources. They can also be used to destroy and defuse bombs, a life-saving feature many times over. However, many countries have banned the production, sale, and use of jammers because they are considered a threat to civilians.
Here's how to hack a wifi blocker
Method 1: Number segment cracking method
The school uses an older wifi signal jammer that can only block the old number segments of PHS, China Mobile, and China Unicom, such as the new Telecom Tianyi 186, China Unicom's Wo number segment, and China Mobile's TD-SCDMA equal number segment, which cannot be blocked. of! Simply put, the Unicom and Mobile number segments starting with 13 15 and all PHS number segments can be blocked! And those starting with 18 will not be blocked!
Method 2: Band cracking method
Because the working principle of the school's wifi jammer device is to block the mobile phone by interfering with the mobile phone signal of the specified band, as long as the receiving and transmitting frequency of the mobile phone is modified, it can be prevented from being blocked. The blocker can only block the mobile phone signal of 900---1800MHZ, while the mobile phone receiving and transmitting frequency of the mobile phone is 850-1900MHZ, which is much larger than the shielding range of the jammer, so as long as the receiving and transmitting frequency of the mobile phone is adjusted to the maximum in the mobile phone settings, the mobile phone signal can be received normally.
Method 3: wifi cracking method:
This method has relatively high requirements on the mobile phone and the environment, but the effect is also the best and the most hidden, provided that the mobile phone must have the function of wifi wireless Internet access, and there must be an available wireless network around it (almost impossible in our high school). After you have found and successfully connected to an available wireless network with your mobile phone, you can still surf the Internet even if the mobile phone has no signal and no traffic. At this time, if you want to find the answer you can't find, you can use Baidu. If you want to send the answer, you can use QQ. Row. A method of hypermetamorphosis.
Method 4 Bluetooth cracking method:
It is suitable for students with a distance of no more than 50 meters to share their answers, and I can also test two adjacent classrooms by myself. Install Bluetooth software like Bluetooth hacker on the mobile phone, and then both sides turn on the Bluetooth visibility full open, there is an option to force the message to be sent via Bluetooth in the software options, enter the answer into the forced send, all open Bluetooth mobile phones will accept To the answer, one person sends the whole class to share. The above method is the method I came up with after several days of contemplation. It is dedicated to all the students in a high school who are distressed by the signal being blocked. I hope that using the above method can free the students from the perverted school and get relaxed and happy!
