The earliest human history, as now is the mobile phone means "wireless", such as the use of the beacon to transmit information to the fire, we usually think this is the first way of passing messages. Indeed not, in our country and the African ancient drum transfer is believed to be the earliest and most convenient way to African drums with special logs may sound transmission to three four thousand meters, and through the "drum relay" and special " Drumming language "in a very short time the news accurately to another tribe 50 km away. In fact, the original phone cable Obo find electronics recycling, whether long-distance transmission drums, flames, semaphore flag colors dancing by [], or today's mobile phones, to realize the message, you need to transfer a large number of layers of a relay station phone row line recovery, the message to reach the destination. However, since that time humans have not found power, so in order to achieve long-range flow quickly deliver messages only wait. Revolutionary change in the history of mankind phone, took place from the electricity as an information carrier. February 17, 1753 phone cable recycling company in the "Scotsman" magazine published an anonymous letter. In this letter, the authors proposed to use the phone's current bold vision. Although not very mature at the time, and the lack of application of the promotion of the economic environment, kept people see the rays of dawn telecommunications era. In 1793, Charles Perry brothers in France between Paris and Lille erected a 230 kilometer-long relay bracket-style way of conveying line information. It is said that the two brothers are the first to use "telegraph" the word of man. With the maturity of this great idea, Morse successfully with the current "on" "off" and "long break" instead of the human character is transmitted, which is famous Morse code. In 1843, Morse received $ 30,000 in funding, he used this money to build from Washington to Baltimore became a telegraph line, length of 64.4 kilometers. May 24, 1844, at a packed Capitol, the Morse with his hands trembling with excitement, manipulating him more than ten years of effort devoted to the successful development of the telegraph, 64 kilometers outside of the Baltimore issued The first telegraph in human history God created what miracle! "Invention of the telegraph, a prelude phone cable recycling telecommunications era, creating a human use electricity to transmit information from this history, the speed of information transfer greatly accelerated.." Tick one despair, "the sound of <1 second: !, telegraph carrying information that people will be able to be transferred to one mile around -1.609344 kilometers. ball took seven and a half laps, this rate was ever a phone tools can not. Here, there is a story must be mentioned that in 1912, "Titanic" after hitting an iceberg, issued a telegram: "305, speed, we hit an iceberg. California "No passenger" a few miles away, "this should be able rescued hundreds of lives, but the radio operator on a ship not find the original phone cable recycling electronic Obo | Kunming phone cable recycling | Obo Obo electrons from Shenzhen Electronic Technology Limited.
