Code Block Caller Id Cell Phone
However, the road is one foot high and the devil is one foot high. There is a kind of radio monitor that can help you get the Code Block Caller Id Cell Phone electromagnetic wave signals in those frequency bands that you can’t take care of. Before the start of the test, the signal strength generated by various legal radio wave devices such as mobile phones, radios, and TVs around the test room are recorded in the test room. After the test starts, in the car, suitcase, and office radio monitors. Start all together, you can receive all the signals of the entire radio wave frequency band. When the cheating tool starts to send answers to the examination room, there will be "an extra piece" of radio wave signals from an unknown source on the monitor. The signal from the cheating tool is difficult to escape. Through the ears of a sophisticated detector. cell phone jammer
When the examinee cheats, when the sending and receiving parties inside and outside the examination room communicate, the “valuable information” such as ABCD answers must first be converted into binary numbers, encoded, and encrypted if necessary, and then the electromagnetic waves of the used band will be processed. Modulation, the information is loaded on the electromagnetic wave signal, sent by the antenna of the transmitter, and the other party in the examination room decodes and demodulates, and restores the ABCD information. However, with this wireless detector, the signal transmission method used by both parties of the cheating technique can be clearly understood within a few seconds. Not only the signal is detected, but the information inside can even be extracted directly and heard in the conversation. Say what. No matter how sophisticated the equipment used by the cheaters is, the nature of electromagnetic waves "near big and far small" must exist. By relying on multiple Code Block Caller Id Cell Phone s placed in different positions, the signal emission can be calculated based on the distance and the strength of the signal. The location of the device, the answer launcher was captured on the spot.
