Keynote Topic: Network Cloudification: SDN-NFV and 5G-MEC with Edge and Fog Computing
The second wave of cloud computing, named network cloudification, in the forms of SDN (Software Defined Networking), NFV (Network Function Virtualization), and 5G-MEC (Mobile Edge Computing), is to centralize and virtualize networking into data centers. It enables operators to offer NaaS (Networking as a Service) with much lower CAPEX and OPEX with larger flexibility because devices become simpler, the number of administrators is less, and service orchestration is easier. It turns parts of communications currently done in hardware into computing done in software. However, the host of these data centers would not be Google-like super data centers as they are too far away from subscribers. The latency requirement of 10ms and 1ms decentralizes cloud computing down to edge and fog computing with CORD (central offices re-architected as data centers) and cellular base stations for SDN-NFV and 5G-MEC, respectively. In this talk, we first argue why, where and when SDN, NFV, 5G-MEC would prevail, and then illustrate how to make it happen with OpenFlow, SC (Service Chaining), NSH (Network Service header), etc. Then we examine how latency requirement dominates this virtualization game by listing key questions to answer in resource allocation in the architectures of SDN, NFV, and 5G-MEC. Their answers are mostly unknown now but would benefit the architects and developers of OpenFlow switches, SDN controllers, SDN-NFV apps, NFV data centers, MEC-enabled base stations, and operator’s infrastructure in general.

Professor Rudolf Mathar
Keynote Topic: Elementary Channels for Quantization, Neural Networks and Molecular Information Exchange
Basic concepts of information theory, namely entropy, mutual information and capacity of channels, are universal tools which can also be applied to analyze information processing of biological systems. The main intention of this talk is to demonstrate the usefulness of information theoretic approaches to neural networks. We will briefly discuss biological neural networks and the functionality principles of neurons. Corresponding idealizing models will include linear, binary threshold, rectifying, censoring and sigmoid neurons. These can be interpreted as information channels, which opens the door to the field of information theory. The capacity and corresponding bounds will be derived providing interesting insight into the control and behavior of neurons. We will also investigate the underlying molecular information exchange by a Poissonian diffusion model.

Recently he has initiated projects in the area of compressed sensing and data science.
Professor Jean Armstrong
Keynote Topic: Visible light communications: a solution to the spectrum crunch?
Standard white lighting LEDs unlike conventional forms of lighting can be modulated at megahertz frequencies. As a result every LED light has the potential to transmit high speed data. This is the basis of important new forms of visible light communications (VLC) and visible light positioning (VLP). This talk will outline the key findings of our research on VLC and VLP and that of other leading groups around the world. The huge potential of this emerging field to deliver very high speed data and accurate indoor positioning will be explained. The many research challenges that still have to be overcome to turn this potential into reality will be outlined. VLC, particularly one form called LiFi, has attracted a lot of media attention. This talk will separate the facts from the hype.

Dr Luca Chiaraviglio
Keynote Topic: Viability of 5G for Rural Communications
Nowadays, at least two billion people are experiencing a complete lack of wireless cellular coverage. Such users live in rural areas and low-income regions, where the network operators are not keen to invest, mainly due to high Capital Expenditure (CapEx) and Operational Expenditure (OpEx) costs, as well as the scarcity of electricity from the grid. We tackle this challenge by proposing a 5G network explicitly designed to serve rural and low-income areas. Our solution exploits Remote Radio Heads (RRHs) mounted on top of Unmanned Aerial Vehicles (UAVs), as well as Large Cells (LCs) to increase the coverage range. In addition, 5G-nodes are powered by solar panels and batteries. Preliminary results, obtained over three representative case studies (located in Italy, Cook Islands, and Zimbabwe) show that providing connectivity in rural and low-income areas by means of the proposed 5G architecture is feasible. At the same time, we also show that the monthly subscription fee paid by the users can be kept sufficiently low, e.g., less than 1 [EUR/month] in low-income areas, and less than 10 [EUR/month] in rural regions.

Dr Murray Milner
Keynote Topic: “Superfast Broadband”, An international case study on how New Zealand is building its superfast broadband Network
New Zealand has been on a journey to deliver Ultrafast Broadband (UFB) to as many premises as possible following a commitment by the Prime Minister leading into the 2008 elections. This resulted in the formation of Crown Fibre Holdings in 2009 and the launch of the UFB initiative in 2011. The initial rollout was focussed on delivering Fibre to the Premise to 75% of urban premises and businesses by the end of 2019. This stage is now well advanced and will be completed ahead of schedule and below budget. In early 2017, the coverage was extended to 87% of New Zealand premises by 2022, including coverage of more than 340 additional towns. This was followed later in 2017 by the extension of broadband to 99% of New Zealand premises using wireless technologies delivering better than 50Mbps downstream by 2025. The latter initiative also includes mobile coverage of more than 1000km of roads throughout New Zealand. The goal of the UFB initiative is to provide consistent 100Mbps downstream and 50Mbps upstream to 87% of premises as a base affordable product and to enable expansion over time to deliver Gigabit and higher speed services with minor incremental investment. Gigabit per second services are already consumed by 5% of New Zealand households today, so Superfast Broadband is expected to rapidly emerge across New Zealand over the next decade.
Dr Milner has spent over 40 years in the ICT industry. He is widely recognised within his profession for his leadership in ICT development in New Zealand. He has been awarded Fellowships to work and study in both the UK and USA during his career. He is a Distinguished Fellow of IPENZ, an active member of IET and a Senior Member of IEEE and is on the editorial panel for the Australian Journal of Telecommunications and the Digital Economy. After spending much of his career with Telecom New Zealand, Dr Milner now runs a busy consulting practice in New Zealand and works extensively with central government, local government and enterprises on ICT strategy, economics and infrastructure development. He is currently Chair of Harmonic Analytics Limited, a Director of Crown Infrastructure Partners, a member of the Digital Advisory Board and the Capital Investment Committee for health, Chair of the Whole of Government Radio Network Governance Board and Chair of the Data Exchange Technical Advisory Board. As a Director of Crown Infrastructure Partners (formerly Crown Fibre Holdings) he has been involved in the rollout of the Ultrafast Broadband initiative across New Zealand since its conceptual beginnings in 2007.
