Chinos logran transmisoón de red Internet a través de la luz

Publicado el 10/19/13.– Investigadores chinos han logrado transmitir a distancia información de la red Internet a través de la luz, en lugar del tradicional uso de ondas de radio (Wi-Fi).

Utilizando un diodo emisor de luz (led) de un vatio, un equipo del Instituto de Física Técnica de Shanghái, consiguió que cuatro ordenadores se conectaran a Internet, informa la agencia EFE.Integrada con microprocesadores, esta pequeña bombilla puede lograr flujos de datos de hasta 150 Mb por segundo, señaló el profesor de tecnología de la información Chi Nan, quien lideró la investigación.

Varios ordenadores con esta nueva tecnología se mostrarán en la próxima Feria Internacional de la Industria de Shanghái, a partir del 5 de noviembre.

Según Chi, este nuevo sistema supera en eficacia al tan extendido Wi-Fi y abaratará costes en la transmisión de Internet sin cables.

“Con los móviles se han establecido por todo el mundo millones de estaciones para mejorar la señal, pero la mayoría de la energía (un 95% del total) se consume en sistemas de refrigeración”, explicó Chi para explicar la ineficacia de los actuales sistemas Wi-Fi.

Frente a ello, “allí donde haya una bombilla habrá señal de Internet”, defiende el profesor, quien subrayó que todavía queda mucho para popularizar esta nueva tecnología, ya que exigiría un rediseño de muchos de los equipos emisores y receptores de telecomunicaciones.
