| Resumo: | Nowadays, telecommunications systems have become a very powerful technology. The ability to be connected to the Internet anywhere on the planet, by simply unlocking a mobile phone, has revolutionized the in which we all live. 5G is arriving with a whole new set of applications (e.g., IoT, connected car, smart cities, augmented reality, etc.). In the near future, it will be necessary to implement a more comprehensive wireless system to satisfy the requirements of our society. Visible Light Communications (VLC) is a candidate technology for the next generation of wireless systems, particularly in those situations where a low-cost solution and the license-free spectrum require enabling ultra-dense deployments of small cells indoors. The major shortcoming of VLC is the large drop in power when an element blocks the line-of-sight between transmitter and receiver. To address this, different Automatic Repeat Request (ARQ) protocols have been implemented in a software-defined testbed to ensure a proper reception of the information. Also, the ARQ signalling was used to enable a VLC-based monitoring system, without the need to deploy additional monitor sensors. |
