Chinese scientists achieve Internet access through lightbulbs. Lifi is faster than Wifi, uses less energy and is safer.

Even harder to escape from the net with this. The net is tightening and closing in.
Soon we will be turning on the light switch to activate Big Brother beamed directly onto the screen inside our head. It will be like FaceTime or Skype, but with a compulsory connection to your controller.

We will have to have the lights on to see because it is always so dark nowadays from the chemtrailing weather control.

And our eyesight is getting worse as we are exposed to more and more, brighter and brighter artificial lighting, day and night.


SHANGHAI, Oct. 17 (Xinhua) — Successful experiments by Chinese scientists have indicated the possibility of the country’s netizens getting online through signals sent by lightbulbs (LiFi), instead of WiFi.

Four computers under a one-watt LED lightbulb may connect to the Internet under the principle that light can be used as a carrier instead of traditional radio frequencies, as in WiFi, said Chi Nan, an information technology professor with Shanghai’s Fudan University, on Thursday.

A lightbulb with embedded microchips can produce data rates as fast as 150 megabits per second, which is speedier than the average broadband connection in China, said Chi, who leads a LiFi research team including scientists from the Shanghai Institute of Technical Physics of the Chinese Academy of Sciences.

With LiFi cost-effective as well as efficient, netizens should be excited to view 10 sample LiFi kits that will be on display at the China International Industry Fair that will kick off on Nov. 5 in Shanghai.

The current wireless signal transmission equipment is expensive and low in efficiency, said Chi.

“As for cell phones, millions of base stations have been established around the world to strengthen the signal but most of the energy is consumed on their cooling systems,” she explained. “The energy utilization rate is only 5 percent.”

Compared with base stations, the number of lightbulbs that can be used is practically limitless. Meanwhile, Chinese people are replacing the old-fashioned incandescent bulbs with LED lightbulbs at a fast pace.

“Wherever there is an LED lightbulb, there is an Internet signal,” said Chi. “Turn off the light and there is no signal.”

However, there is still a long way to go to make LiFi a commercial success.
“If the light is blocked, then the signal will be cut off,” said Chi.
More importantly, according to the scientist, the development of a series of key related pieces of technology, including light communication controls as well as microchip design and manufacturing, is still in an experimental period.

The term LiFi was coined by Harald Haas from the University of Edinburgh in the UK and refers to a type of visible light communication technology that delivers a networked, mobile, high-speed communication solution in a similar manner as WiFi.
