Conducted at Tampere University and Brno University of Technology, Asad Ali's research focuses on advancing wireless strategies using high-frequency millimeter-wave (mmWave) spectrum to enable truly immersive XR experiences. His work addresses key connectivity challenges associated with directional communication, such as signal interference and beam misalignment, which are common in high-frequency networks.
Improving wireless connectivity for XR devices
With XR technology promising to transform industries from entertainment to healthcare, reliable, low-latency connectivity is essential. In his dissertation, Asad Ali examines the primary network limitations affecting XR performance and proposes solutions to increase data rates, reduce latency, and improve reliability for wearable XR devices.
Asad Ali’s research focuses on the specific demands of mmWave-based directional communication networks. His work emphasizes improving beam alignment, minimizing interference among wearable devices, and developing strategies to improve performance in high-density, multi-user, and highly dynamic environments.
To address the infrastructure challenges that immersive XR experiences present, Asad Ali’s dissertation introduces a system-level framework to enhance connectivity, tackling issues like beam misalignment and interference within mmWave networks. While mmWave frequencies enable high data rates, they are susceptible to signal degradation from movement or environmental obstacles.
"With the rise of XR applications, networks need not only to deliver high bandwidth but also to adapt to user movement and prevent signal disruptions," Asad Ali explains. His research incorporates advanced mathematical models, such as queueing theory and stochastic geometry, to evaluate the performance of wearable XR devices in different scenarios, contributing insights that can improve connectivity for future XR devices.
Asad Ali’s research has been published in six scientific papers: two high-impact journal articles, three conference papers, and one magazine article. These works appear in prominent venues, including IEEE Wireless Communications Letters, IEEE Communications Letters, IEEE Communications Magazine, the IEEE International Symposium on Personal, Indoor, and Mobile Radio Communications, and the IEEE International Conference on Communications.
This research was supported by the H2020 A-WEAR ITN/EJD program and the Faculty of Information Technology and Communication Sciences.
