5G için hybrid TV yayını ve görünür ışıkla haberleşme ile kablosuz ınternet sağlama

Visible light communications (VLC) is a future promising communication technology to be utilized in future 5G networks satisfying energy efficient outdoor and indoor communications with existing hardware components such as LED bulbs, TV screens and camera receivers. Existing outdoor VLC architectures have signi cant challenges in terms of data rate, robustness to outdoor channel and requirements of high power transmitter resources. In this thesis, a cellular outdoor VLC architecture is introduced by utilizing arrays of LED bulbs as transmitters and telescopic cameras as receivers. The proposed system promises high performance cellular uplink communication channel reaching hundreds of Kbps for the ranges of tens of kilometers. It exploits array transmitters consuming less than hundred Watts power consumption at each house and telescopes improving the communication range. Besides that, the proposed system architecture is combined with existing TV downlink radio frequency (RF) network architecture to realize internet service providing (ISP) system with low cost and low complexity system design. Networking architecture utilizes commercially available display screens at home for downlink data. Performance analysis and comparison of various next generation display technologies such as quantum dot (QD) and organic light emitting diode (OLED) based displays are performed in terms of response time, color gamut, spectral color output, contrast ratio and power consumption. VLC-RF hybrid architecture promises widespread utilization of ISP services in suburban areas with high reliability, low cost and energy e cient system design utilizing already available hardware platforms.
