Wireless Fidelity

Over the years, the overdependence on Wireless Fidelity (Wi-Fi) for data transmission necessitated the need for an alternate and more reliable means of communication, hence, Light Fidelity (Li-Fi). It involves the use of Light Emitting Diode to transmit data by blinking (i.e. switching them on and off) at a speed not noticeable to the eye. This paper proposed the development of the Li-Fi system using off the shelf electronic components. This would make the system an indispensable means of communication in the nearest future. This data transmission system is different from those in existence because expensive components were not in the design, invariably reducing the overall cost of the implementation.

Transmission Speed

This paper puts forward the design of communication system based on FPGA. USB controller CY7C68013 is widely used for its faster data transmission rate and diverse interface way which provide a simple and seamless connecting interface for the ATA, FPGA and DSP . This paper introduces the basic working principles of the controllers, and uses its affiliate FIFO method in order to produce corresponding control signal in FPGA with VHDL. It realizes fast data transmission between PC and FPGA through USB. Test results shows that the scheme transmission speed fast, data accurate, and can be extended to other need through the USB fast data transmission system.
