Communication, a long time ago, was just a line, connected to both ends, knocking long and short signals, building a crypto world, and later, more and more signals were transmitted, and the data transmitted by the cable became larger and larger. Iron wires became copper wires, and now optical cables made of quartz, the driving on the road changed from horse power to oil and then to electricity, and the materials under the road changed from mud to cement to asphalt. The world has been turned upside down for a century. Changes, live broadcast, VR/AR, video, medical treatment, navigation, remote control furniture, even these things are all in the past. The holographic projection, telemedicine, autonomous driving, and smart home brought by 5G will be the next generation. The refurbished horn sound.
