Advance! German researchers turn LED lights into network devices

The German Folaoen Hof Institute of applied researchers and optical wireless network together, the LED lamp has become a common living room network equipment, intelligent mobile phone or computer to help users to receive or send data. Allegedly, this technology can be developed with the help of flashing LED lights to transmit data from the air, so that the transmission rate of 1000 megabits per second, and in different colors of LED lights, the expression of different data rates of transmission.

LED lamp is very popular in daily life, whether it is the room, office, street can find this product. LED lights in addition to lighting for people, there is no more powerful function?

The researchers Anagnostis Paraskevopoulos said that he personally believed that the first use of this technology or will be put to the conference room, exhibition, industrial production environment and the hospital more professional places.

But he also said that this technology will lead to a series of problems. For example, if a LED lamp is powered by a battery, this means that a shorter range of received signals will be better. Another problem is that the strong sunlight will affect the LED light signal receiver, which is applied to outdoor LED equipment has some damage. Its performance varies with distance, and the transmission speed is only 20 megabits per second over a distance of about 20 meters.

In addition, this kind of visible light communication also requests the sight line communication condition, after all, the light can not have the function of penetrating the wall. However, through the coordination of all LED lights in the room, the user can still receive any signal in any corner of the room.

The limitations of this research and development is not that every user wants his phone or computer to receive the signal, the head must have a light-emitting LED lights. However, the research team said that the day after the launch of R & D or invisible infrared light LED lamp.
