The researchers
of a Germany Applied Research Institute will combine wireless networks and
optical, then LED lights can use as a network device in ordinary living room to
help user's smart phone or computer to receive or send data. Allegedly, This
technology research can make use of flashing LED lights transmit data from the
air. The transmission speeds can reach up to 1,000 megabytes per second. And in
three different colors of LED lighting to express different transmission data
rate.
The
Institute's researchers said that they personally thought that the first test
of the technology will be put to use in meeting room, exhibition, industrial
production environment as well as hospitals and other places which is more
professional.
But
they also said that such technology will lead to a series of prombles. For
example, if the LED lights are use battery powered, which means that within a
short range of the received signal will be better. Another problem is that the
strong sunlight will affect the LED light signal receiver, which is used in
outdoor LED apparatus will having some damage. As the distance changes, its
performance will change, out of the range of 20 meters can only at speed of 20
megabyte per second s.
In
addition, the visible light communication also requires line of sight
communication conditions, after all, the light can’t penetrate walls with
functional. But to coordinate all LED
lights inside the house, you can still received signals from any corner of the
room.
The limitations
of this research is that not every user wants must have a head glowing LED
lights when they are using phone or computer to receive the signals, But the
research team said that will research and developed invisible infrared LED
light in the future.
