Scientific and technological "hard dishes""! LED lights help sci fi scene walk into reality"

The morning of May 20th, the activities of science and technology of Henan province in 2017 week launch ceremony of Zheng Luoxin national innovation demonstration zone and the integration of science and technology achievement promotion will be held in Zhengzhou. Zheng Luoxin created his own district full year, and coincided with the scientific and technological activities week, the provincial science and Technology Department to prepare the public "science and technology" "hard dishes": May 20th, 21, held at the promotion meeting on display more than 200 high-tech!

Using visible light communications, download a high-definition movie in 0.2 seconds. In the past, it is very difficult for us to imagine things, but in the day before the processing method of optical and electrical cooperated by The PLA Information Engineering University research team, broke through the visible space channel interference suppression technology, key, enter the stage of integration, design and Realization of miniaturization, real-time communication rate increased to 50Gbps (bits per second), the equivalent of 0.2 seconds to complete a high-definition movie download.

In May 20th, the reporter also saw the high-tech. Visible light communication Ta-ble - Fi system consists of a light and a companion device. The staff, based on the application of visible light communication technology from the LED lamp, a LED lamp can become a high-speed network hotspot, has no lights, lights, appears to be very limited, but when the unit is expanded from a light expanded to a small lamp, even more, will constitute a a huge visible light communication network. The network will not slow down because of the increase in the number of connections, and there is no need to worry about being stolen or tapped. This will be comparable to the situation in science fiction.
