 Did the sinking of Titanic bring mobile phones decades ahead of schedule?

What is the connection between the tragedy of Titanic and the birth of mobile phones? After all, on April 10, 1912, when the Titanic made its only voyage, it excluded travelers. People at that time should not have heard the word mobile phone anywhere in the world. Can the phone be moved? For the people of that time, it was unimaginable.

The origin of mobile phones known to the public

Before reading this article, I believe you have read a lot of articles about the origin of mobile phones, consult the interactive encyclopedia, and you will easily find comments on the origin of mobile phones. At that time, the research and development of wireless telephone technology was mainly for military purposes. In 1938, the U.S. Neil Laboratory made the worlds first mobile phone for the U.S. military.

In 1946, Alexander Bell Laboratories built the first commercial mobile phone. At that time, AT&T rented a large mobile radio phone, which customers could install on trucks.

The real product, which can be called a civil mobile phone, dates back to April 1973, when a man stood on the streets of New York and pulled out a radio phone about two bricks in size, causing passers-by to stop and stare. This man was Martin Cooper, the inventor of the mobile phone. At that time, Cooper was an engineer and engineer of Motorola, a famous American company. The radio telephone he used was the first mobile phone in the world.

So the question is, what does the mobile phone that only appeared in 1973 have to do with the sinking of Titanic in 1912?

Radio is the Enlightenment Teacher of Mobile Phone

This should also start with radio, which is a discipline separated from the development of physics. It rose from the end of the 19th century. Through the hard work of countless scientists, it accumulated a large number of experimental and theoretical research results and gradually developed.

In 1864, Maxwell, a British scientist, summarized the work of his predecessors and put forward the electromagnetic theory for the first time. In 1895, Popov performed a newly built radio receiver and sent a telegram 250 metres away the following year. A few months later, Marconi was able to communicate about 1,500 meters. Since then, communication distance has been increasing. In 1900, Popov radioed instructions to break the ice 45 kilometers away, saving 27 fishermen who broke into the sea. On December 12, 1901, Marconi successfully carried out a radio communication experiment across the Atlantic Ocean, about 3,200 kilometers away. Since then, the world has entered a new era of radio communication.

With the development of radio, a new term emerged - ham, so-called ham, short for amateur radio enthusiasts. The term ham was originally used to ridicule professional cable operators in the 19th century who had poor technology. In 1900, amateur radio developed with the development of amateur radio. Numerous amateur radio enthusiasts used radio to communicate, even to replace the official. Non-commercial reporting, which looks like todays self-media, has its own small circle, sharing information with each other and sharing technological insights.

Titanic sunk concession phone seed germination

In September 2015, Discovery Channel reported that on April 15, 1912, the so-called Never Sunk Titanic sank on its maiden voyage to New York. After extensive coverage by amateur radio players and unscrupulous mutual quotation of incorrect information, it caused adverse social reactions, and the U.S. government therefore tightened its control.

As a result, many amateur radio players try to get rid of the official control, so they seek a way of walking wireless communication. The concept of wireless intercom system came into being, which is the Enlightenment of mobile phones. Although amateur radio will eventually be regulated because of its shape, the sinking of Titanic has undoubtedly become a fuse. The problem of amateur radio regulation caused by the world-shaking events may lead to the Enlightenment of this idea several years or even decades ahead of schedule.

This idea also affected some technology companies at that time. In 1940, Motorola introduced SCR-300 during World War II, which was the first equipment widely called walkie-talkie. It was an infantry radio station with a back. This radio works in FM mode at 40-48MHz, providing communication support for infantry.

Later Motorola also launched SCR-536, which is a single-armed radio station operating in AM mode between 3.5 and 6.0 MHz, which is a real handheld radio.

Although nearly a hundred years have passed from the germination of ideas to the birth of conceptual products, peoples enthusiasm for the development of mobile phones has not diminished slightly during this period. There is no gap between them. The wheel of history is rolling forward, and the progress of science and technology is changing with each passing day. Nowadays, our mobile phones have comprehensive functions. They can not only call at any time, but also integrate multimedia entertainment. Experience, while enjoying all this, do you inadvertently think about its history in your spare time?
