Includes index.3-030-61407-7 Introduction -- Optical wireless communication -- Components of a visible light communication system -- VLC for underground positioning and monitoring system -- Underground positioning and monitoring system implementing with VLC embedded -- Conclusion.This book provides a chronological literature review of optical wireless communication, followed by a detailed blueprint of a visible light communication (VLC) setup with the key characteristics of LEDs and photodetectors. Next, the optical channel impulse response and its description for different possible topologies is presented together with a description of the optical and electrical setup for both optical transmitters (oTx) and optical receivers (oRx). Different single carrier and multi-carrier modulations particularly applied in visible light communication setups are also presented. Both the optical and electrical modules of oTx and oRx are simulated and then prototyped and tested as embedded devices in an underground positioning and monitoring system for a continuous real time identification of the personnel on the main underground galleries where the illumination network is already installed. Presents a comprehensive look at visible light communication technology, both in description and application; Shows where and how VLC has been launched on the market as an alternative or partner technology to the existing wireless communication technologies based on radio frequency; Includes special focus on underground positioning and monitoring with embedded VLC.Wireless CommunicationWireless Communication.002Riurean Simona Mirela1223407Leba MonicaIonica Andreea CristinaMiAaPQMiAaPQMiAaPQBOOK9910483254503321Application of visible light wireless communication in underground mine2849578UNINA01041nam0 22002771i 450 UON0048477620231205105304.934978-37-296-0949-520180118f2017 |0itac50 bagerCH|||| 1||||ˆDas ‰kürzere Leben des Klaus HalmRomanLukas HolligerBaselZytgloggec2017300 p.21 cm.Dono “Pro Helvetia”IT-UONSI ELVTIII/0450CHBaselUONL003102833.914Narrativa tedesca, 1945-199021HOLLIGERLukasUONV237753764318ZytgloggeUONV273810650ITSOL20240220RICASIBA - SISTEMA BIBLIOTECARIO DI ATENEOUONSIUON00484776SIBA - SISTEMA BIBLIOTECARIO DI ATENEOSI ELV T III 0450 SI 24728 7 0450 Dono “Pro Helvetia”Kürzere Leben des Klaus Halm1551656UNIOR
