Emerging XR applications, including Holography, Augmented, Virtual and Mixed Reality, are characterized by unprecedented requirements for Quality of experience (QoE), largely exceeding those currently attainable. To cope with these requirements, noticeable efforts and a number of initiatives are ongoing to enhance the current communications technologies, especially in the direction of supporting ultra-low latency and increased bandwidth. This work proposes an architecture that puts together the key enablers to support future XR applications, highlighting the shortcomings of existing technologies and leveraging the ongoing innovations. It demonstrates the feasibility of the proposed architecture by describing the processes driving the platform with relevant use case scenarios, and mapping the envisioned functionality to existing tools.
This paper presents initial findings from a study to identify road operator and power distribution system operator operational requirements for dynamic wireless power transfer systems for electric vehicles. A number of solutions are currently being developed around the world but in order for them to be effective and desirable in the transport domain, they must be able to meet the key operational requirements. The results presented in this paper aim to identify key requirements, assess to what degree they should be met and discuss possible implications of these requirements on the design of dynamic wireless power transfer systems for EVs. Requirements such as misalignment tolerances between primary and secondary coils due to driver behaviour, power transfer section segmentation and separation, possible impacts on road network performance, power and energy supply capability, and implications of peak power demand profiles under varying traffic conditions are considered and addressed.
Wireless electric vehicle charging will pose an additional strain on existing grid infrastructure. Additionally, dynamic or "on the move" charging schemes may result in increased demand variability due to fragmented charging duration caused by charging lane layouts and traffic. A simulation environment has been set up in order to; assess the impact of dynamic wireless charging on the grid, evaluate energy storage requirements for demand smoothing and finally to explore the possibility of integrating solar energy into the dynamic wireless charging infrastructure.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
