Abstract:

Ka-band broadband satellite communications services called high-throughput satellite (HTS) are now emerging all over the world. The National Institute of Information and Communications Technology (NICT) in Japan has established a user consortium to identify the future needs of communication-satellite users, has studied satellite-communication system concepts covering those needs, and has settled on technical issues for increasing communication speeds. The NICT has also come up with a conceptual design of a next-generation large-capacity satellite communication system. A feasibility study has been conducted into a prototype system, and development has begun. Our goal is to realize 100-Mbps-per-user, high-speed, large-capacity mobile communication using the Ka-band, and to implement flexible (variable-frequency bands and steerable beam) relay technology that can handle traffic fluctuations. According to projected increases in traffic and users, the feeder-link capacity in terms of frequency bands between satellites and terrestrial gateway stations will become exhausted soon. In addition, the radio regulations tend to make it difficult for RF bands to be allocated. To solve these issues, the feeder links could be achieved optically instead. The NICT has initiated the high-speed communication with advanced laser instrument (HICALI) project, for which NICT will develop an onboard ultra-high-speed laser communication system. The objective is to realize 10-Gbps-class optical feeder-link technology for a geostationary Earth orbit. The next step is to verify this technology on orbit, which would contribute to the next-generation hybrid (RF and optical frequencies) HTS. Here, the hybrid HTS communication system is introduced.

Abstract:

Despite the rapid adoption of communication technology across the world, there are still almost 4 billion people living without mobile coverage in emerging markets. This creates a huge demand for connectivity services in remote locations. The rapid adoption of advanced communication services and mobile devices in the developed world and the stark lack of connectivity infrastructure in developing counties is creating a deep digital divide, which is putting millions of people at disadvantage and hampering the opportunities for economic growth of many countries. The ability to provide mobile coverage in remote locations is vital for building a healthy information infrastructure in developing countries where poor connectivity is a barrier to education, business growth and economic prosperity. As our world is becoming increasingly interconnected, providing affordable connectivity to everyone, everywhere is more important than ever. The author will discuss how nano-satellites are transforming the satellite industry and will explore the potential of this technology for providing affordable connectivity and digital inclusion to everyone, everywhere. Topics he will be able to cover include: what are the key trends driving adoption of nano-satellite technology in different markets; what are the potential applications of this technology and the market opportunities? The role of affordable connectivity and small sat technology for driving digital inclusion and; a collaborative approach to innovation: how satellite companies, telco providers, start-ups and established enterprises can work together to make affordable connectivity a reality.

 

 

Louis Petingi

Title: Measuring the performance of wireless networks represented as probabilistic graphs by application of network reliability models

Biography:

Louis Petingi obtained his PhD in Computer Science from Stevens Institute of Technology (New Jersey, USA) in the fields of Extremal Graph Theory and Network Reliability. He is currently a full Professor of Computer Science at the College of Staten Island (City University of New York).  His research comprises: application of network reliability models to measure if performance objectives of communication networks are met and; to introduce new techniques to characterize graphs with maximum number of spanning trees among competing topologies with equal number of vertices and edges. The latter problem has been tackled by many graph theorists since the 1960’s because of its applicability to the design of reliable networks.

 

Abstract:

In this talk we address the problem of measuring the performance of wireless networks by modeling these networks as probabilistic directed graphs. The communication between network's nodes a and b is modeled as stochastic directed link from a to b, whose probability of failure is the outrage probability, that is, the probability that the capacity of the communication channel is less than its transmission rate. In current literature wireless networks are usually represented as binary networks, i.e., an undirected edge exist connecting two communication nodes if both are within each other reach. Probabilistic networks allow differentiation of two nodes as they may have different transmitting/receiving characteristics, by introducing two antiparallel directed links connecting the nodes with possibly different probabilities of failure. Then to measure specific performance objectives of a network can be accomplished by application of new or classical network reliability mathematical models, the latter introduced in the 1960s. Moreover traditional optimization problems as for example finding dominating sets in undirected graphs to establish possible sets of backbone nodes in sensor networks can be equivalently accomplished in probabilistic networks by application of network reliability models. The pros and cons of modeling communication networks as probabilistic graphs versus traditional representations are discussed.

Abstract:

The development of machine-to-machine communications systems has been increasing recently, especially considering that they have a wide range of applications in smart cities and the Internet of things (IoT). However, with the massive number of connected devices in such applications, the problem of message collision becomes a vital factor that significantly affects the reliability and performance of the M2M systems. The emergence of smart phones, cloud computing, and networking on the Internet has created a type of consumer increasingly accustomed to doing everything using smartphones to check bank balances, purchases, watching movies on mobile devices, etc. From here these consumers wonder why health systems cannot provide appropriate applications for similar service using the blockchain technology. Which led to the emergence of information technology companies working in the different fields that attract investment capital with the flexibility to design applications that meet the needs directly to groups of users at the same time emerged obstacles for IT companies, notably lack of access to data with no agreement on how to distribute the resulting economic benefits for smartphone applications and at the same time IT officials in search of the potential of blockchain technology in IoT for example to answer the following basic questions: Who should pay for applications and electronic services? What is the evidence of the effectiveness of the services provided by the application and which are the reason for paying the wages; what conditions should be available to be the starting point for developing applications with a business model? We believe that the blockchain solution is to strengthen cooperation between health providers and technical companies by enabling the exchange of health data to enable more efficient and adaptive health care delivery. The national health system must take into account that the framework in the area of health care data must be updated from the demand for standardized standards of patient health record to providing data access through application interfaces using blockchain. The framework of the health electronic services system will be operated by accredited third parties and can be directed by the health system as well.

Abstract:

Over the past decade, the Internet has transformed into the backbone connecting a variety of smart devices. The advent of the Internet of things (IoT) has been a major driver for the evolution of wireless communication technologies. The IoT scenario presents a variety of applications, whose demands can be contrasting to that of conventional human-to-human (H2H) communication. The fifth generation (5G) wireless communication technologies are focussing on extending the support for IoT through two categories – massive machine type communication (mMTC) and ultra-reliable low latency communication (URLLC). While the mMTC categories aims to serve a large number of devices hosting delay-tolerant applications, the URLLC category mainly deals with the communication aspects of delay-sensitive, critical IoT applications. Also, new technologies like massive multi-input multi-output (MIMO) and non-orthogonal multiple access (NOMA) are being considered to further improve the 5G IoT performance. In massive MIMO, the base station employs a large number of antennas to serve the devices. The increased number of antennas provides an additional dimension domain, which can be utilized for beamforming  (to improve coverage and transmit directed messages to the devices), improved channel estimation and enhanced detection of user signals. In traditional 4G technologies, each user is allocated a separate set of orthogonal resources, which limits the number of simultaneously served users. In order to support the IoT scenarios with a large number of users, new access methods like NOMA are being evaluated, where two or more users share the same set of orthogonal resources, but are either separated in the power domain or the code domain. These technologies have rekindled the interests of academics and industry researchers towards developing novel mechanisms for efficiently supporting the IoT evolution through the 5G network. 

 

 

Session Introduction

Giuseppe Destino

King’s College London, Strand Campus, UK

Title: 5G NR positioning: a new opportunity to achieve sub-meter accuracy with mobile networks

Biography:

Giuseppe Destino received his Doctor of Science degree at the University of Oulu in 2012, MSc (EE) degrees simultaneously from the Politecnico di Torino, Italy and University of Nice, France in 2005. Currently, he is working as Academy of Finland Postdoctoral Research Fellow as well as Project Manager of national and international projects at the Centre for Wireless Communications of the University of Oulu, Finland. In 2017, he worked at the Nokia Bell Labs, Oulu, under the Nokia Bell Labs and University of Oulu Joint Centre for Future Connectivity. Since 2018, he is associated with King's College London, Centre for Telecommunication Research (CTR), where he carries on activities on positioning and millimetre-wave technologies. His research interests include wireless communications, millimetre wave radio access technologies, especially, on algorithms for channel estimation, hybrid beam forming and positioning. He served as a member of the technical program committee of IEEE conferences.

 

Abstract:

Millimeter-wave communication is considered one of the key enablers for 5G systems as it contributes to achieving high data rate with very wideband transmission, high beam forming gain and massive MIMO techniques. However, the wireless link in the extremely high frequency band (mm W band) is characterized by quasi-optical behaviour, i.e., line-of sight dominant and a few reflected (single bounce) paths. Leveraging this property along with the capability of beam forming and large signal bandwidth to radio-based positioning, accurate and reliable location-awareness can be achieved all time via mobile network. More specifically, a new approach for localization can be developed to (i) determine user's position from a single access point, and (ii) determine the orientation of the user, with respect to the access point.  In this talk, we will illustrate all the benefits of this new localization solution, a brief introduction to the underpinning mathematical model and the trade-off with communications. Focus is on the analysis of the system model, achievable localization performance and dependency with system design parameters such as number of antennas, OFDM signal formation and interoperability with GNSS. The talk is centered around the application of autonomous driving use-case tackled in the EU H2020 5GCAR project.

Abstract:

In a transition to automated digital management of broadband networks, communication service providers must look for new metrics to monitor these networks. Complete metrics frameworks are already emerging whereas majority of the new metrics are being proposed in technical papers. Considering common metrics for broadband networks and related technologies, this paper offers insights into what metrics are available, and also suggests active areas of research. The broadband networks being a key component of the digital ecosystems are also an enabler to many other digital technologies and services. Reviewing first the metrics for computing systems, websites and digital platforms, the chapter focus then shifts to the most important technical and business metrics which are used for broadband networks. The demand-side and supply-side metrics including the key metrics of broadband speed and broadband availability are touched on. After outlining the broadband metrics which have been standardized and the metrics for Nmeasuring Internet traffic, the most commonly used metrics for broadband networks are surveyed in five categories: energy and power metrics, quality-of-service, quality-ofexperience, security metrics, and robustness and resilience metrics. The chapter concludes with a discussion on machine learning, big data and the associated metrics
