OPTICAL WIRELESS COMMUNICATION (OWC)

Optical Wireless Technology for the Future Intelligent and Fully Connected World

 

Abstract: To go beyond the realization of the Internet of Everything, which will be addressed by the full deployment of 5G networks, and to add to the future telecommunication networks the notion of intelligence, the future 6G networks require extremely low latency and high reliability, scalability, as well as enhanced quality-of-service and quality-of-experience in sophisticated scenarios. This can be seen as a prerequisite to going towards a fully automated and intelligent world where billions of devices are connected via the local- and public-based cloud networking. Furthermore, the need to precise localization, as well as improved energy efficiency and reduced carbon footprints become of premier importance. These requirements mainly arise from emerging multimedia applications and the exponential increase in the number of smart sensors and devices. 

To address these requirements and the associated challenges, optical wireless communications (OWC) are seen as a promising approach in a variety of application areas, given the limited available radio frequency spectrum. Indeed, thanks to the numerous operational and technical advantages offered by OWC, we have been witnessing increased research and development activities in the past two decades or so, which have led to the development of new solutions capable of delivering ubiquitous, high date rates, and low-cost wireless network access in a variety of scenarios. Nevertheless, there exist still several technical challenges that need addressing before a wide-spread deployment of OWC. In particular, the recently launched COST Action CA19111 on European network on future generation optical wireless communication technologies (NEWFOCUS) aims to serve as a global networking platform through capacity building of all relevant stakeholders including universities, research institutions, major industry players, small medium enterprises, governmental bodies, and non-governmental organizations.

The aim of these sessions is to provide a forum for researchers from academia and industry to present the latest research and development findings as well as sharing their views on different aspects of OWC systems from fundamental to applied. The session will cover ultraviolet, visible, and infrared bands from design to standardization.

3- Optical Wireless Communication inherits the merits and the problems of both radio and fibre systems

Abstract: Radio-based wireless communication has a track record of many decades of improving performance. We see not only increasing bit rates offered to all users, but also dramatically increasing numbers of users that can be served simultaneously. The increasing density of Gigabits per second per square meter calls for MIMO approaches to separate user signals, and Medium Access Protocols that resolve contentions among various users. However, we increasingly see the benefits of communicating via light: It is naturally confined to smaller areas, say to a single room or to a targeted light beam. Directed light beams may require less effort to separate signals (resulting in lower power consumption) and can make it easier avoid conflicts in wireless traffic (making it easier to guarantee a Quality of Service and low latency). While commercially available office LiFi systems cover areas of several square meters, future indoor systems embrace the concept of sectorized beams, using arrays of LEDs or VCSELs and angular selective receivers. Eventually, the steering of thin laser beams promises fibre-like connectivity speeds per user. The research in this area benefits from experience in fibre communication but faces many of the challenges of wireless communication such as user mobility, such as the need to track users and the need to be robust against channel variations. These two fields traditionally have a different focus of research. In fibre, the channel conditions are as predictable and stable and not subject to major variations. Hence, a speeds race on Gbit/sec demonstrated on an optical table can be seen as an indicator of the innovation progress. In contrast to this, the radio community focussed heavily on statistical channel modeling and variability. To make the step from a system that worked once in a lab towards a reproducible that reliably works everywhere, anytime, under any circumstance with any use case one cannot rely on a finite number of experimental tests only.  Similarly, for optical wireless communication, we see challenges in creating reusable models for channels, line of sight blockage, cell lay-outs, user and device mobility, etc. Moreover, wireless access points need to cover an area that is orders of magnitude larger than the detector surface. As the receiving device needs to be capable of detecting signals from a wide range of angles, the etendue limitations of the receiver optics and an unavoidable low-pass nature of the electronic link chain form bottlenecks in the achievable bit rate.
