Title of the talk: Advanced Antennas for 5G and 6G

Abstract: 5G and 6G future wireless communications systems are poised to revolutionise our society and industries. They will provide ultra-high reliability, extremely high data-rates, ultra-low latency and high level of privacy and security for communications among people and moving platforms on the ground, at the sea, and in the sky. They will support the inter-working of robots, drones and other autonomous machines. These will pose unprecedented challenges to antenna and RF technologies. Future antennas must support extremely wide band operation, from microwave to terahertz frequencies. They must be light, compact and conformal to moving platforms. They need to be low-cost and consume minimum power. They will support simultaneous communications by using high gain multi-beams. They will be reconfigurable. These challenges provide abundant opportunities to antenna and RF researchers and engineers. In this talk, we shall discuss these challenges and possible solutions, and explore the potential and limits of some emerging technologies. We shall show a glimpse of some of the pathways we have taken at GBDTC @ UTS to develop cutting-edge antenna and RF systems for the future.

Title of the talk: Towards Terabit Wireless Communications

Abstract: With the ever increasing demand for wireless connectivity, mobile data traffic continues to grow following the “omnify” principle, i.e., the data rate is observed to have an order of magnitude increase every five years, making wireless communication one of the most dramatic game-changing technologies. At this “omnify” pace, data rate for wireless transmission is expected to increase by a hundred time from current 10 Gbps within the next decade, achieving terabits per second. As the 5G mobile system emerges, ground based networks become more and more mature. However, there are still significant technological challenges to extend wireless coverage through the integration of space and terrestrial networks and to replace the last mile wired network with terabit wireless links. In this presentation, the evolution of wireless communication technologies is firstly reviewed, and the importance of millimetre wave radio frequency backbones in the integrated space and terrestrial networks is then addressed. An overview of the applications and technical challenges of the emerging terahertz wireless communications is given afterwards. Finally, some enabling techniques for improving spectral efficiency and power efficiency for millimetre wave and terahertz communications are discussed.

Title of the talk: IoT and Blockchain: Technologies, Challenges, and Applications

Abstract: The Internet of Things (IoT) is poised to transform our lives and unleash enormous economic benefit. In this talk, we discuss a wide range of IoT technologies and their applications, as well as the security and trust implications. Blockchain, a distributed ledger, was initially designed as a secure financial transaction tool. Remarkably, its cryptographic security benefits, such as user anonymity, decentralization, fault tolerance, transaction integrity and authentication, can be used to resolve security and trust issues of IoT. In UTS, we are working with industry to develop next generation IoT and Blockchain technologies to achieve real time tracking and monitoring from production plants through export supply chains to overseas markets. A Blockchain enabled data platform has been developed to secure IoT data records, enable transparent and trusted data sharing. Smart contracts are developed to manage and automate commercial transactions following the commodity flows. In this talk, we will discuss the benefits, limitations, and challenges of IoT and Blockchain. I will present some of our latest project results in IoT and Blockchain applications.

Title of the talk: Empowering the collocation of 3G/4G/5G base station antennas for 5G infrastructure

Abstract: The fifth-generation (5G) mobile communication systems are widely hailed as a key enabler for the next wave of industrial innovation and economic growth. Currently, there is a global race to develop cutting edge technologies for 5G and to create innovative strategies to deploy 5G networks cost-effectively. The stakes are high and the competition is fierce. To ensure 5G coverage, many 5G base stations will need to be installed. Acquiring new sites for base station antennas would lead to substantial increases in costs and environmental pressure. Therefore, the most promising approach envisioned by the mobile industry to address these economic and environmental challenges is to integrate 5G base station antennas into the existing 3G/4G ones, thus reducing the number of new base station antenna sites required. Correspondingly, the spacing between antenna elements servicing either the same bands or different bands will become smaller. This smaller distance typically results in two problems, namely, strong mutual coupling and distortion of the radiation patterns of the elements. This talk will introduce some new scientific methods and engineering techniques that can mitigate the interferences, thus enabling cost-effective 5G infrastructure deployment.

Title of the talk: Vehicle-to-Everything (V2X) Communications

Abstract: Vehicle to Vehicle (V2V) communication is another important field of the next generation wireless communication. It requires ultra-low latency and ultra-high QoS level. There are currently two standards in this area: DSRC based IEEE 802.11p and LTE V2V/V2X, both will operate in the same dedicated automotive band - 5.9 Ghz. Therefore, a coexistence scheme is needed to coordinate two standards and mitigate the interference in the same band. We proposed the coexistence and interference management solutions for DSRC and LTE V2V/V2X, enhance the performance by link aggregation of various DSRC (802.11p) and LTE V2X sources such as other automobiles, infrastructure, and pedestrians. Unmanned Aerial Vehicles (UAVs) as another important application in V2X, possess multiple desirable features such as high-manuverability, ease of deployment and flexibility which make them promising candidates in a wide variety of applications. In the recent years, UAVs have attracted a lot of attention in the area of wireless communications. However, UAVs have their inherent limitations. One major drawback in UAVs is the limited available energy. We proposed energy efficient collision avoidance algorithms for multi-UAV systems, a complete energy model for UAVs based on empirical studies of battery performance and energy efficient path planning for UAV-BSs for improved user coverage and throughput.
