Design And Implement Of A Visible Light Communication Circuit For Radio Frequency Spectrum Mitigate In Mobile Data Communication

Abstract

The societal dependence upon wireless systems continues to rise due to mobile data interchange. According to the Federal Communication Commission the current allocation of 38GHz 5G Cellular is to a great extent pointing to the crowding of the radio frequency spectrum especially in Mobile data communication. Therefore this study will grant an opportunity to explore visible light communication as one of the emerging technologies to serve as an alternative to provide solution to these challenges and further prototyped a complete circuit for Mobile Data Transmission using light emitting diodes and or visible light communication. The visible light communication (VLC) refers to the communication technology which utilizes the visible light source as a signal transmitter, the air as a transmission medium, and the appropriate photodiode as a signal receiving component. This study appraises the existing literature on Solid State Lighting (SSL), with emphasis on Light Emitting Diodes (LEDs) to ensure that visible light can be used to mitigate frequency spectrum for mobile data transmission. The study focused on the Prototyping of Visible Light Communication complete Circuit for Wireless and particularly for mobile Data Transmission; an analogue circuit that can be integrated with a computer or mobile phone, which can send some form of data using visible light LEDs from a transmitter, and decoding it with an appropriate photodiode as a receiver. The complete circuit comprising all the three phases of the transmitter, the free space and the receiver was tested with PROTUES 8 Professional software which was designed specifically for simulation of electrical signals and audio data of 3kH to 20kH was sent consistently and precisely over a short distance at a fair speed and the initial goals for the functionality of the new system which is to send audio, at a data rate of at least 10 Mbps was achieved. The study shows that Visible light communication has the prospective to provide high speed mobile data communication with improved energy efficiency and communication security/privacy due to its unique characteristics and advantages. It is therefore to so extent certain that the Visible Light Communication can complement the Radio Frequency (RF) based mobile communication systems in designing high-capacity mobile data networks and can be incorporated as an innovation in the oncoming 5G network Technology. It will be of greater advantage when error control mechanism and Dimming Support is integrated in the subsequent research work.
