Control! Let "black radio sound" pin
Playback:
Recently, some airline flights in the Tianjin airport over and operation center contact, constantly under unknown noise interference, the captain and commander on the ground can be heard. The noise reduction processing, the captain of the noise in Headset found unexpectedly is advertising.
Investigation, this "mysterious waves in the air" interference source is not approved by the radio management department of the "black radio".
Question: what is the "black radio"? The harm? How regulation?
Answer:
"Black radio is pseudo base station arbitrarily sending illegal signal for radio transmitter." Recently, the information economy and the competitiveness of Beijing University of Posts and Telecommunications Research Center Director Ceng Jianqiu expresses when accepting a reporter to interview, the emission power, signal than conventional base station, and a single set of equipment for a wide range of.
According to general understanding, a 1000 Watt radio transmitter diameter black covered more than 20 kilometers, 1 kilowatts can cover about 60 km in diameter. At the same time, if the antenna is high enough, the small power can cover a large area. Tianjin city has seized a 1000 watts of power black radio, erected in the downtown high-rise, signal covers the entire Tianjin city except Jixian County.
"This launcher is actually very simple, just use the FM transmitter, MP3, transformer, antenna feeder and antenna simple parts can be completed." University Academy of Sciences Professor Tu Chinese defense tells a reporter, this kind of wireless equipment signal frequency is stronger, and even can interfere with satellite.
Along with the rapid development of information technology in China, black radio these illegal setting not only pose a threat to the national aviation flight safety, but also disturbance to the radio, communication business, its harm is immeasurable.
"The provisions of the state broadcast with a fixed frequency, black radio was not bound by." Dumbo network CEO, Chinese communication industry well-known observers Xiang Ligang said, black radio when playing the ad easy hopping to civil aviation command band, such as being completely interference, in the United States aircraft could. If the aircraft taking off and landing in the effects of black broadcast radius, the situation is more dangerous.
"Must emphasize, use and supervision of the wireless device has a strict legal system and regulations, no matter black broadcast will not lead to aircraft missing, its existence is not allowed." The Defense said coating.
This, Ceng Jianqiu also hold the same view. He believes that the aviation interference incidents occur frequently illustrated black radio has posed a threat to aviation safety. From the national information management perspective, this behavior destroys public information facilities, is a serious violation of the law clear.
Reportedly, since 2013 since October, black radio equipment only Tianjin city had seized 19 sets of many, but still is banned repeatedly more than.
The reporter survey found that the majority of black radio equipment is purchased through a network. In addition to the purchase of simple, radio enthusiasts can also self assemble, which is one of the reasons for difficult to deal with the black radio.
Equipment ordinary broadcast 2000 Watts is only slightly larger than the computer chassis, weighing about 35 kg, the transfer is very convenient, even the antenna, transmitter, player a total of less than 50000 yuan. Will only play content input, can be 24 hours unattended loop. At the same time, has the very strong convenience and covert network purchase, easy to avoid regulatory control.
Ceng Jianqiu said: "the black radio equipment price is not high, easy to buy, the user to the equipment was confiscated and do not care, which caused by the repeated and spread."
"Black radio is a product driven by interests." Xiang Ligang said, the forced into radio frequency within a formal play spam is because profitable, with market, driven by the interests of illegal.
The social dangers and security risks black radio big, how to eliminate the endless black radio? Tu Defense said, should raise public awareness of the popularization of the use of radio, radio safety knowledge, explore new management mode, further preventing harm produced black radio.
"At present, China's relevant laws and regulations on the manufacture and sale of industrial chain has black radio regulatory gaps, the urgent need to improve." Ceng Jianqiu said that the relevant regulatory authorities through active monitoring work daily, strengthen pair of black radio upstream (production equipment), middle (Internet or other sales channels) and downstream (a person or company to use equipment) system of investigation, take the initiative to attack the integrity of the "black" industrial chain.
Ceng Jianqiu suggested that regulatory departments should jointly with relevant law enforcement departments and enterprises to actively mobilize the masses to force, once found black radio station, timely hit, even combined with private enterprises, with a high pressure situation against such violations. In addition, we should actively to the local government leader reporting the relevant situation, take the initiative to strive for the support of the relevant government departments.
"To let black radio disappear completely, we must pay attention to, from the source to crack down, establishes the corresponding mechanism and strict management system, once found rapidly strike." Xiang Ligang said.
