LAN Lamps: transmission through light waves instead of radio waves

Another safe way forward for wireless.

Eileen O'Connor


LAN Lamps – transmission through light waves instead of radio waves

In Japan, the Ministry of Communication, in conjunction with scientists, telecommunications operators and electronics manufacturers, is in the process of forming a consortium to develop the use of visible light for the wireless transfer of large quantities of data. The new technology shall be ready to be introduced into the market within the next five years. The consortium aims for a data transfer speed of 100 Mbps. This means the technology will also be capable of transmitting moving images in high resolution over short distances.

The new technology would provide an alternative to today’s wireless Lan networks in closed environments. The technology is based on LEDs which transmit data as waves within the visible light spectrum, which can then be received by a computer interface placed within the cone of light. The vision: Wherever you are, in a restaurant, the library or at home – just connect the lamp to an electrical cable which also carries data, switch on, and immediately start streaming videos on your screen under comfortable lighting.
