Seminar Li-Fi Technology 23 The project Running from October 2012 to September 2016, UP-VLC is an ambitious EPSRC-funded £4.6 million Programme Grant which will explore the transformative technology of communications in an imaginative and foresighted way. The vision is built on the unique capabilities of gallium nitride (GaN) optoelectronics to combine optical communications with lighting functions and especially on the capability to implement new forms of spatial multiplexing, where individual elements in high-density arrays of GaN based LEDs provide independent communications channels, but can combine as displays. The engineers who work on this project say: “We envisage ultra -high data density - potentially Tb/s/mm2 - arrays of LEDs driven via CMOS control electronics in novel addressing and encoding schemes and in compact and versatile forms". Recently, by integrating CMOS electronics with GaN based micro-LEDs, they have developed CMOS- controlled color-tunable smart displays. The color-tunable LED pixels in these displays have a modulation bandwidth of 100 MHz, thus providing simultaneously a wavelength-agile source for high-speed visible light communications. The programmable dynamic images generated from such a micro-display system are shown below (red „Tetris‟ and green Firework). [ 18 ] Fujitsu Laboratories Working Fujitsu Laboratories has developed a technology that modulates the colour of light emitted by LED lights in such a way as to be undetectable to the human eye, but that can still embed ID data in the light that is cast on an object. We will talk about two basic concepts: the first one is Key features of this technology and the second is Reflectance compensation . The key feature of this technology is that information could be embedded using colour modulations. For more clarification, we know that colour LEDs combine the three lights of red, green, and blue (RGB) to produce a range of colours. By modulating the intensity of the light emitted by each of the three component colours along the time axis, ID data can be embedded in the light cast onto an object, even with very small variations. Data for one ID is attached to each individual LED light. Figure 13 shows transmit and receive data with colour modulation.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
