ANTENNE TV SANS FIL DRIVER
This 5G technology will allow the emergence of new services: remote driving of trains without a driver on board, deployment of automated trains, coupling / decoupling of line trains, etc. ) which provides for the parallel use of several radio access techniques including 5G. Thus, thanks to the possibilities of this technology and due to the obsolescence of the current ground-train communication system used in Europe, GSM-R (Global System for Mobile Communication - Railway) will be replaced by FRMCS (Future Railway Communication System). Fifth generation (5G) cellular networks promise significant improvements in throughput, capacity, latency and reliability. The digitization of services and autonomous and connected mobility require the development of V2X (vehicles for all) communication systems offering increasingly high transmission speeds, capacity and a level of security. This trend isgeneral in all areas of society and particularly in the field of transport. With the development of digital technology and the Internet of Things, there is a growing need for transmission rates per user, capacity, security and flexibility of communications systems. This thesis, led in the framework of a CIFRE grant between THOMSON multimedia and the IETR (Rennes Institute for Electronics and Telecommunications), provides some clue to this problem. The HIPERLAN2 specification, achieving data rates up to 54 Mbps in the 5 GHz spectrum, is among them and the question naturally arises as to determine the potential of a MIMO-based physical interface. Yield unprecedented spectral efficiencies.įew existing WLAN standards can cope with high data rate multimedia services. This concept generalizes all previously known transmission systems and allows a far more sophisticated processing of space to A major breakthrough came recently with the multiple-Input Multiple-Output (MIMO) communication architecture that uses multiple-antenna arrays at both transmitter and receiver ends. Obviously more exibleĪnd less expensive than their wired counterparts, the future of WLAN is hindered by the capacity of keeing the pace with the exponential growth in data rate sustained by multimedia communications. Until recently restricted to office applications, wireless local area networks (WLAN), propelled by advances in electronics and signal processing, is ermerging as the most promising technology to bring connectivity in home environment.
