Data Transfer Through Light

In the future, large amounts of data can be sent via light. A reading light enough for someone to be able to surf the internet. Fast and no significant obstruction.
If many users use mobile phones or surfing the internet at the same time, then transfer the data to be sluggish. This may happen in a football stadium filled. In New York, which is a hotspot for users of the iPad, iPhone and smart phones, slow Internet access has become a daily. Toward sunset, a wireless data transfer hardly work anymore. Moreover, waves that are used to send data to each other so that the reception of data menadirkan often disrupted and disjointed.
Professor Harald Haas to develop new technologies for wireless data transfer: light-voiced. Wireless optical data communication, that's the key word. Haas wants to use electromagnetic waves of light that looks eye. The basic principle is very simple: The LED deliberately supplied with electricity is not stable. Flashing light at high speed so that the eye can not catch it. This flicker of light that contains information. Laptops and the iPhone is equipped detector can capture and read information from the LED lamp. In this way, very large amounts of data transferred at high speeds using light morse technology. In the future, street lights and even traffic lights could be used to transmit data.
This technology could revolutionize data transfer and the lives of everyday people. Wireless broadband - anytime and anywhere, faster than average speed Internet at home or in the office today. This technology enables many applications, such as data transfer patients in the hospital. Currently, it can not be done because the data transmission interrupted by computer tomography. Another possibility is the transfer of video data in the living room to watch movies. Data transfer can not be tapped because the light does not leave the room. Light also produces no electro smog that is often criticized for environmental activists. In addition, the transfer of data via light is very energy efficient.
Throughout the world there is fierce competition for researching this technology. Utilization of light, says Haas, will revolutionize wireless communications.
