Optical communications technology, Li-Fi is 10 times faster than Wi-Fi, will replace Wi-Fi?

Nakamura Shuji invented efficient blue light LED, which led to a wave of lighting revolution. He was invited to lecture about Academia Sinica today, wireless optical communication technology Li-Fi will replace Wi-Fi, to a densely populated country, it will be a great boon.

Now at the University of California-Santa Barbara, Nakamura Shuji, and Akasaki Yong Amano Hiroshi, in 2014 2 Japanese academics who won the Nobel prize winning official reason is "invention efficient blue light emitting diode, the birth of bright and energy saving white light".

Last year Nakamura Shuji was elected honorary academician of Academia Sinica, President Liao Junzhi issued today by the central badge, and delivered a speech. For a glimpse of the teachers and students with master style venue, the largest international conference center at the almost All seats are occupied. After the meeting, there were many people waiting in line to sign and take pictures with Nakamura Shuji.

Nakamura Shuji mentioned after the reporter, LED development so far, there are a lot of applications is that he had the unexpected, such as Academia Sinica scholars have cancer cells isolated. Now, he devoted himself to laser lighting research, and related applications are still in the initial stage, the current life can be seen only about headlights, but he believes that the future will have great opportunities, and can replace LED.

Another popular technology for Nakamura Shuji is the wireless optical communications technology, Li-Fi, that uses LED or laser light as a medium for data transmission. In the near future, the lights in the office will be base stations, projecting indoors and allowing computers and home appliances to connect to the internet.

Nakamura Shuji said, using LED's Li-Fi, transmission data faster than Wi-Fi 10 times, laser light Li-Fi faster than a hundred times. Another key is that, Wi-Fi has bandwidth limitations, the number of users in a certain area will be too much, uploading and downloading will be very card, and Li-Fi will not be limited.

Nakamura Shuji said, Taiwanese people may think Wi-Fi is very good, but the future of Li-Fi will make transmission faster, download the movie also do not have to wait. Densely populated areas, such as the urban areas of mainland China, will be a great boon to Li-Fi.
