v2x technology refers to vehicle wireless communication technology.
The so-called V2X is exactly the same as the popular B2B and B2C, which means vehicle to everything, that is, the exchange of information between the vehicle and the outside world. The Internet of Vehicles has laid a new direction for the development of automotive technology by integrating Global Positioning System (GPS) navigation technology, vehicle-to-vehicle communication technology, wireless communication and remote sensing technology, achieving compatibility between manual driving and automatic driving.
To put it simply, models equipped with this system, in autonomous driving mode, can automatically select the driving route with the best road conditions through the analysis of real-time traffic information, thus greatly alleviating traffic congestion. In addition, through the use of on-board sensors and camera systems, the surrounding environment can also be sensed and rapid adjustments can be made to achieve "zero traffic accidents." For example, if a pedestrian suddenly appears, it can automatically slow down to a safe speed or stop.

Optical Telephone
The first wireless telephone conversation in the world occurred in 1880, using an optical telephone, by Alexander Graham· Invented and patented by Bell and Charles Sumner Trent. Photophones use modulated light beams to transmit voice signals. At that time, there was no equipment that could provide electricity, and lasers were not even mentioned in science fiction novels. Their invention did not seem to have practical value at the time, and the effectiveness of calls would be limited by sunlight and weather. As with optical telephones and free-space optical communication systems, there must be no objects blocking the light beam between the transmitter and the transmitter. Decades later, optical telephones were applied to military communications.
Early Work
David E. Hughes used a transmitter in 1878 to transmit radio waves hundreds of meters away. Maxwell's electromagnetic theory was not widely known at that time, so contemporary scientists regard this invention as the result of induction. In 1885, Thomas Edison used vibrator magnets for induction transmission. In 1888, Edison deployed a signal transmission system for the Hay Valley Railway. In 1891, he obtained a patent for a radio using inductors (U.S. Patent 465,971).
In 1888 Heinrich Hertz demonstrated the existence of electromagnetic waves, which became the basis for most subsequent wireless technologies. Hertz proved that electromagnetic waves travel in straight lines in space and can be received by experimental equipment, but he did not continue to conduct other related experiments. Jagdish Chandra Bose developed an early radio detection device at that time, which also helped to understand the characteristics of electromagnetic waves with wavelengths within a few centimeters.
Radio
"Wireless" initially refers to the radio receiver, or transceiver (a device that can be used for both transmission and reception). It has been used as early as the era of wireless telegraphy. similar equipment. Nowadays, the term "wireless" refers to modern wireless communications, such as cellular networks and wireless wideband communications. The term wireless also refers to any application that does not require wires, such as "wireless remote control" and "wireless energy". conversion” without distinguishing whether the actual applied technology is radio, infrared or ultrasound.
Guglielmo Marconi and Karl Braun won the 1909 Nobel Prize in Physics for their contributions to wireless telegraphy.
