In recent years, wireless communication has significantly evolved due to the advanced technology of smartphones, portable devices and the rapid growth of Internet of Things, e-Health, e-Commerce, intelligent transportation systems and social networking. Forecasted by Cisco, the wireless mobile traffic will be dominant over the data network as part of the new connected world in 2020s and the upcoming 6G and beyond wireless technologies. More recently, we have seen growing research activities in Optical Wireless Communications (OWC) as a complementary wireless technology to the more established radio frequency (RF)-based systems such as cellular, Wi-Fi and Bluetooth, to overcome the spectrum crunch and provide high data rates in urban environments and crowded locations. The OWC technology offering advantages such as free license, wide bandwidth, inherent security and no RF-based electromagnetic interference, which makes it very attractive for the emerging 5G wireless communications.
Nevertheless, the widespread deployment of OWC systems in the three major bands of infra-red, ultra-violet and visible light, will face several challenges including the weather effects (mostly for free-space optical communication in outdoors), channel impairments, eye and skin safety regulations, compatibility with existing networks, mobility (mostly in outdoor environments), cost per device and volume, and device/system performance. These challenges have led to a substantial volume of research activities both at academia and industry at a global level to make OWC systems a more reliable and viable wireless option as part of the future integrated networks.
The special Section on OWC aims to bring together researchers and software and hardware developers from academia and industry to present, share and discuss their latest research results on OWC. We solicit high-quality technical paper submissions based on original research and will select some suitable papers to be presented at this special issue.
