This paper will outline proof-of-concept demonstrations of multi-Gigabit/s optical wireless transmission and will discuss challenges faced by the optical wireless in meeting Tutu re requirements such as supporting multiple users, low profile transceivers and resilience against noise and obstructions.
High-speed optical wireless communications have been widely studied, and the infrared wavelength is a good option for short-range high-speed applications. In this paper, infrared short-range optical wireless systems and the silicon integration of beam steering function are discussed.
Optical technologies have long been investigated to provide efficient backhaul transport for mobile networks and have the potential to also provide direct wireless transmission to support ultra-high-speed connectivity. In this paper, we review our recent progress in optical wireless communication systems utilizing infrared free space link for in-building personal area networks.
The indoor localization is a highly demanded function in high-speed wireless communication systems due to their limited directivity and mobility features. In this paper, we propose an indoor localization system based on the use of optical wireless technology in conjunction with a single-channel imaging receiver. The localization function can be realized by using either the received optical signal...
In this paper the recent research progress on highspeed personal area infrared optical wireless communications is reviewed. A 10 Gb/s downlink and up to 2 Gb/s uplink are experimentally demonstrated. The indoor localization function is also summarized.
In this paper we propose a silicon integrated optical phased array based on edge couplers for efficient beam steering in optical wireless communication systems. A 1×4 phased array is proposed and simulated, and results show that it can steer the beam over a wide range (>20°) and operate over a wide bandwidth (>55 nm). In addition, the proposed beam steering device is compact, easy to fabricate,...
In this paper we experimentally demonstrate an indoor optical wireless based localization system with single channel imaging receiver for personal area network applications. The results show that an accuracy of ∼3.81cm can be achieved.
