dc.description.abstractThis project aims to implement a communication system based on Li-Fi using OOK modulation. As this modulation is quite simple, its bitrate will not be very high. However, for our project it will be enough. Besides, this system ought to work from 1 to 100 MHz. This technology is quite new and it is destined to become the replacement of the Wi-Fi in the coming years. Its strong point over other technologies is the solution of coverage problems which currently exist. To do that, Li-Fi will provide coverage wherever there is a light source (with Li-Fi implemented) plugged into the electric power network. We have divided the project into two big blocs: 1. Hardware is the first block and it is set up by: the USRP, the TX (array of LEDs), the RX (photodiode), the current driver, a bias-tee and amplifiers. To accomplish this task, we have chosen the most appropriate components for the design. On the other hand, we have been very careful how to implement the system. Avoiding radiation and trying to get the highest range of coverage in order to reach further targets. 2. The second block is the software development, which is implemented by ALOE 1.6 development tool. We have developed the different modules needed to have our modulation operative. Finally, it should emphasise our interest in building a complete LI-FI system, which is possible to make an implementation feasible to be commercialized. So, throughout the project we have taken into account the components used and we have been testing items, which are already marketed (e.g. LED lighting).
