"Hard food science and technology"! The LED lamp power into the "real" science fiction scene ""

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 the area over the years of age, and coincides with the science and technology week, the provincial science and technology department for science and technology "hard vegetables" to the public in May 20th, the 21 day promotion conference held an exhibition of 200 a number of high-tech!

The use of visible light communication, 0.2 seconds to download a high-definition movie. 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 lamp 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. This is not because the increase in the number of network connection and slow, do not have to worry about theft, hacking, this will be comparable to the situation in the science fiction story.
