Block The Number On Cell Phone

Signal jamming was common during World War II and the Cold War. In addition to preventing news from reaching the intended country, broadcast jamming also spread at the time. During the Cold War, Soviet and Western transmitters even participated in a "power race", with the cell phone jammer trying to increase its broadcast power. After the end of the Cold War, things began to change. When the Soviet Union came out of power, Western militaries generally had more traction and control over innovative technologies. However, because "signal warfare" is not required, Block The Number On Cell Phone is classified as illegal in many countries, with the exception of government, military and defense applications. Interfering signals can be caused by mechanical or electrical interference. The main differences between them are explained below. This technique is an ancient disease. This technique uses devices such as decoys, mirrors, rice husks, etc. to reflect the signal back, which is then reflected back to the source, resulting in a false return. These devices are very eye-catching.

For example, corner reflectors are often attached to decoys (or moving objects designed to confuse radar operators) to make them look like real aircraft. Rice husks, on the other hand, are made of aluminum glass fibers of varying lengths. All of these are valid, but not very accurate. This could defeat the purpose of strengthening the invisible signal barrier. Except for the four types of examinations stipulated by the state, the use of Block The Number On Cell Phone in other examinations is strictly prohibited. Yesterday, in response to the recent indiscriminate use of mobile phone jammers to affect public communications, the Provincial Radio Regulatory Commission and the Provincial State Security Bureau convened four companies including China Telecom, China Mobile, China Unicom, and China Netcom. Communication operators, provincial admissions office, self-examination office and other units jointly discussed and standardized the use and management of mobile phone jammers. Going forward, any illegal use of cell phone jammers will be punished. According to relevant national regulations, only four types of national examinations, namely the general college entrance examination, the adult college entrance examination, the postgraduate examination and the self-study examination, are allowed to use mobile phone blockers.
