Unit 1. Introduction
During the introduction, the framework of the visible light communications and their role in the radioelectric spectrum is presented. Within this framework the need for exploiting alternative bandwidth is shown. After that, the communication needs of the smart industry and how the visible light communications are explained. Finally, a brief overview of the standards that regulate the visible light communications is carried out.
Unit 2. Propagation of the visible light
Design of a transmission scheme for visible light communications and presentation of its elements, i.e., LED lights, photodiodes, amplifiers¿ Description of the point-to-point channel and the effects of the diffuse components within industrial environments. Highlight the difference between the free-space optical channel and the radiofrequency channel.
Unit 3. Modulation and detection of information through visible light communications
Analysis and implementation of modulation, signal detection and decoding schemes for visible light communications. Single carrier and multi-carrier (OFDM) schemes. Management of the constraints given by the features of the optical channel. Multi-transmitters (MIMO) optical schemes.
Unit 4. Geolocation based on visible light communication
Implementation of geolocation services based on the deployment of LED light in industrial environment. Modeling and accuracy of the geolocation services.
Unit 5. Internet of Things based on visible light communications
Management of sensors networks in industrial environment through visible light communications. Compatibility with traditional standards based on radiofrequency and grouping of the set of communications through and optical gateway.
Unit 6. Practice, practical case
Study of practical case employing the knowledge obtained through the subject. Use of Matlab for simulations.
