LEDs May Offer Future Internet Connectivity
The energy usage of homes and workplaces has been lowered with the use of LEDs or Light Emitting Diodes, commonly found in clocks, televisions, remote controls, and appliances. Now a team at the Chinese Academy of Sciences has discovered a way to use LEDs to connect to the internet.
The new technology was recently demonstrated at the Shanghai World Expo. Although the current maximum speed is 2 megabits per second, continuing research will increase speed. The LEDs have also been used to control appliances and remote controls.
The light from LEDs is both more economical and also more powerful than traditional lighting, and it also generates signal modulation as the LED is turned on and off. With the increasing adoption of smart home technology, LEDs may play a significant role in the future.
The electromagnetic waves emitted by wireless technologies have been a subject of concern due to their possible harmful effects upon the human body. They can also interfere with electronic equipment that is in close proximity. Since there are no radio waves in LED transmission, it could provide an alternative and less harmful source for the future.
In the US, the National Science Foundation is also funding research into smart lighting technologies using LEDs. Researchers at Boston University are seeking to develop a next-generation wireless network based on the technology.
