: on 12th July 2011. He used a table lamp with an LED bulb to transmit a video of blooming flowers that was then projected onto a screen behind him. During the event he periodically blocked the light from lamp to prove that the lamp was indeed the source of incoming data.

At TEDGlobal, Haas demonstrated a data rate of transmission of around 10Mbps -- comparable to a fairly good UK broadband connection. Two months later he achieved 123Mbps. Back in 2011 German scientists succeeded in creating an800Mbps (Megabits per second) capable wireless network by using nothing more than normal red, blue, green and yellw 0. Slide 14: Basic concepts- LED ie Light emitting diode can be switched on and off faster since operating speed of LED is less than 1 μs, than the human eye can detect, causing the light source to be appear continuously. This invisible on-off activity enables a kind of data transmission using binary codes. Switching on and LED is a logical ‘ 1 ’, switching it off is a logical ‘ 0 ’.It is possible to encode data in the light by varying the rate at which LED ’ s flicker on and off to give different strings of 1s and 0s. Modulation is so fast that human eye doesn ’ t notice.

How LI-FI Works?: How LI-FI Works? Operational procedure is very simple, if the led is on, you transmit a digital 1, if its off you transmit a 0. The LEDs can be switched on and off very quickly, which gives nice opportunities for transmitting data. Hence all that us required is some LEDS and a controller that code data into those LEDs. We have to just vary the rate at which the LED’s flicker depending upon the data we want to encode Thus every light source will works as a hub for data transmission. Slide 22: GigaShower and Giga-MIMO are the other models for in-house communication.

Brother Lc-970bk Program here. There a transmitter or receiver is mounted into the ceiling connected to, for example, a media server GigaShower provides unidirectional data services via several channels to multiple users with gigabit-class com- munication speed over several metres. This is like watching TV channels or listening to different radio stations where no uplink channel is needed. In case GigaShower is used to sell books, music or movies, the connected media server can be accessed via Wi-Fi to process payment via a mobile device. Shibram Chakraborty Short Stories there.
