Abstract

Radio-based communications systems are fundamentally limited by the low bandwidth of radio-frequency channels compared to light and the power required to transmit data. Our project is a short-range, light-based communication system between two devices inspired by the Zigbee protocol. Using photodiodes and visible light LEDs operating at different wavelengths, as well as a low-power microcontroller, our project aims to network electronic and computing devices with full-duplex communication, low power requirements, and data rates comparable to Zigbee (~100 kbps). Once we are able to link two devices together and transmit data, we will extend our system by connecting multiple transmitters together to improve reliability, as well as potentially improve communication speeds to 1 Mbps and beyond while maintaining low energy usage. The intended use case of this system is networking internet of things (IOT) devices, which are increasingly becoming more prevalent in homes and are using radio bandwidth that could otherwise be allocated to more network- and computation-intensive devices, such as laptop computers.
