Speech Title: 5G IoT Networks: from Massive Access to uRLLC
Abstract: Connected smart objects, platforms and environments have been identified as the next big technology development, enabling significant society changes and economic growth. The entire physical world will be connected to the Internet, referred to as Internet of Things (IoT). The intelligent IoT network for automatic interaction and processing between objects and environments will become an inherent part of areas such as electricity, transportation, industrial control, utilities management, healthcare, water resources management and mining. Wireless networks are one of the key enabling technologies of the IoT. They are likely to be universally used for last mile connectivity due to their flexibility, scalability and cost effectiveness. The attributes and traffic models of IoT networks are essentially different from those of conventional communication systems, which are designed to transmit voice, data and multimedia. IoT access networks face many unique challenges that cannot be addressed by existing network protocols; these include support for a truly massive number of devices, the transmission of huge volumes of data burst in large-scale networks over limited bandwidth, and the ability to accommodate diverse traffic patterns and quality of service (QoS) requirements. Some IoT applications have much stringent latency and reliability requirements which cannot be accommodated by existing wireless networks. Addressing these challenges requires the development of new wireless access technologies, underlying network protocols, signal processing techniques and security protocols. In this talk, I will present the IoT network development, architecture, key challenges, requirements, potential solutions and recent research progress in this area, particularly in 5G.

Speech Title: Towards Smart and Reconfigurable Radio Environment: Intelligent Reflecting Surface Aided Wireless Networks
Abstract: Intelligent Reflecting Surface (IRS) has recently emerged as the new wireless communication research frontier with the goal of achieving smart and reconfigurable radio propagation environment for the future wireless networks via passive and tunable signal reflections. Featured by orders-of-magnitude lower hardware and energy cost than traditional active arrays and yet superior beamforming performance as well as other new functionalities, IRS is expected to be a key driving technology for B5G/6G wireless networks, especially for enabling them to migrate to higher frequency bands (mmWave/THz). More importantly, IRS will fundamentally reshape today’s wireless network with active nodes solely to a new IRS-aided hybrid network comprising both active and passive components co-working in an intelligent way, so as to achieve a sustainable capacity growth with low and affordable cost in the future. In this talk, we will provide an overview of IRS, including its motivations, promising applications in wireless network, communication basics, new design challenges, and their state-of-the-art solutions. Important directions worthy of further investigation such as multi-IRS aided networks will also be discussed.

Speech Title: Designing Networks for Resilience and Cost Effectiveness
Abstract: Two primary objectives in telecommunications network design are resilience and cost effectiveness. With our dependence on the Internet, its resilience is increasingly crucial to humanity as its failure has grave socio-economic consequences. Cost effectiveness is not only important because of the need to be profitable and competitive, but also because of the societal need to conserve energy and combat global warming. Two important characteristics of the Internet are long haul cables that provide efficient communication between different continents and protocols that are structured in layers. This presentation will discuss methodologies for optimizing network design to achieve resilience as well as cost effectiveness considering optimal cable path planning and multilayered networks. The importance of cable path planning optimization lies in the fact that there are now over a million kilometers of internet cables and with plans for additional million kilometers of cables to be laid in the next decade, at a cost of tens of billions of dollars, to meet the overgrowing traffic demand generated by new technologies and services. As the complexity of the internet protocols increases with the introduction of new technologies, the multi-layering characteristics of such protocols are here to stay. Therefore, network design optimization and the understanding the tradeoffs between cost and resilience is key for cost savings and viability of the internet. Special consideration must be given to realistic conditions and scale applicable of both internet cabling and protocol design. Solutions that address these problems and issues will be presented and discussed in this presentation. This work was funded by HK RGC grants CityU123012, CityU11200417 and CityU8/CRF/13G.
