New Optical Wireless Frontier: Design Challenges of Multi Gigabit Wireless

Grant number: DP170100268 | Funding period: 2017 - 2021

Completed

Abstract

This project aims to improve the coverage, mobile access, miniaturisation, bandwidth and networking of optical wireless. As connected machines become the primary consumers of the Internet, technologies for wirelessly connecting devices, processors, storage and display devices at very high speeds become necessary for mission critical services and applications. Gigabit wireless access needs to overcome shortages in the radio-frequency spectrum and provide scalable bandwidth and wider coverage. Optical wireless transmission is a real alternative to current wireless systems because its connection speed of tens of gigabits/second means it can work efficiently with wired optical networking technol..
