High-Speed Optical Wireless Communication System for Indoor Applications

Abstract

A novel high-speed optical wireless communication system for indoor personal area networking applications is proposed and studied. A proof-of-concept experiment at 12.5-Gb/s wireless transmission has been successfully demonstrated with limited mobility. When integrated with a WiFi-based localization system, high-speed optical wireless communication with a mobility feature can be achieved over the entire room. The performance trade-offs between the maximum beam footprint and overall bit rate have also been studied and quantified experimentally and the results show that error-free (BER<;10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-9</sup> ) reception can always be achieved for a wide range of bit rates from 1 to 12.5 Gb/s.
