ESIB, Saint Joseph University of Beirut, Lebanon, Melhem El Helou


Low-Power Wide Area Networks (LPWAN) have recently gained considerable attention in the Internet of Things (IoT). The key objective of these wireless technologies is to connect low-power devices over very large areas, with low data rates. LPWANs are promising for various emerging IoT applications, complementing the traditional cellular and short-range technologies.

In this tutorial, we present the recent advances in LPWAN technologies with focus on LoRaWAN and NB-IoT. We analyse the link level and system level design aspects. We further focus on link budget analysis and radio network dimensioning for both LoRaWAN and NB-IoT. Precisely, we present best practices in the network design and deployment of these technologies. Acquiring such best practices is of paramount importance for the engineering and optimization of LPWANs. We also provide a comparative scientific analysis of the performance of LoRaWAN and NB-IoT in terms of coverage and capacity.

Finally, we cover the research directions and scientific challenges in these technologies. Particularly, we present research directions for radio resource management in both LoRaWAN and NB-IoT.


Objectives and Motivation:

Our tutorial sheds light on the recent advances in LPWAN technologies for IoT. We answer the following crucial questions related to the design, performance evaluation, and challenges of LPWAN: How do LPWAN complement traditional cellular and short-range wireless technologies? What are the fundamental mechanisms that enable to meet the LPWAN requirements? What are the major design choices made in the LoRaWAN and NB-IoT specifications? How do we evaluate the performance of a LoRaWAN and NB-IoT deployment in terms of coverage and capacity? What are the recent research directions for radio resource management in LoRaWAN and NB-IoT?

Our approach fills the gap in the state-of-the-art by introducing a set of generic building blocks that enable to meet the LPWAN requirements. We provide an overview on the two major technologies in LPWAN, namely LoRaWAN and NB-IoT, covering the radio interface, and the physical and protocol architectures. Participants will acquire deep understanding of the major design principles of both technologies and how they integrate the generic building blocks of LPWAN. Our approach is supported by novel results on path loss models and original use cases with numerical computations comparing the performance of LoRaWAN and NB-IoT in terms of coverage and capacity. We also provide a comprehensive scientific overview on the state-of-the-art and the promising research perspectives for radio resource management in LPWANs. This overview is of paramount importance for researchers to get a classification of the approaches, tools, and latest research results related to LoRaWAN and NB-IoT.

Tutorial Length:



Software Defined Networking (SDN) has now become the preferred option for managing today’s large heterogeneous networks, because of the flexibility that it offers over traditional networks. SDN applications can replace and/ or extend the functionalities implemented in the underlying hardware devices of a conventional network.

SDN includes a gamut of network technologies, which increases the network’s flexibility and agility. It is beneficial to the virtualized server as well as storage infrastructure. The network policy and forwarding planes of SDN makes the network directly programmable. It is a centralized approach to network management, where the underlying network infrastructure is abstracted from applications. SDN applications are in mainly in cloud computing or mobile networks.

This tutorial is intended for the developers who are new to SDN application development. It will help in upskilling the audience with SDN concepts and will provide a step-by-step guide on writing SDN applications using POX controller along with demonstration and hands-on sessions. It will also provide an opportunity to share knowledge and exchange information with the experts working in this domain and thus foster collaborations.

Importance and Timelines of the Tutorial:

State-of-the-art in networking domain clearly indicates the demand of network softwarization to manage complex networks of the future. SDN applications are an important component in this evolution. So, there has been an increasing focus on developing SDN applications.

Network behaviour can be influenced by the Management/Application plane and that is where the Application development comes into the picture. There is an enormous potential of innovation in playing-around with management-plane-applications, provided the underlying hardware supports it. Changing networks dynamically is possible using applications which are running on top of the SDN controller. Many network functions have been softwarized such as firewall, learning switches etc. More such applications can be developed and existing applications can be enhanced. In order to do this, one must be familiar with SDN application development.

SDN application development is a key topic of interest in 2018. The tutorial will provide valuable insight into the domain of SDN Application Development and will appeal to the combined audience of researchers, students, participants who are novice in SDN and industry participants at WPMC 2019

Toutorial 3 – Radio Spectrum Challenges and Opportunities for International Mobile Telecommunications (IMT) including Future Wireless Technologies (FWT)

Ashok Chandra


According to a recent assessment made by the International Telecommunications Union (ITU), more than 850 million young population globally uses internet. At present, uses of internet by young people in Least Developed Countries (LDCs) is upto 35%, as against 23% globally. The mobile broadband users are likely to reach more than 5 billion globally by the end of this year. Making mobile broadband (commonly known as International Mobile Telecommunications-IMT), more affordable with huge widespread wireless-based networks, is a massive and challenging task.  

Simultaneously, the next Industrial revolution, the Industry 4.0 will be based on smart technologies using huge bank of sensors, short range devices (SRDs)/ultra-wideband devices (UWB). It may be mentioned that for IMT including Mobile Broadband (MBB), Industry 4.0 applications and other wireless based devices for example Intelligent Transport System (ITS), all need radio spectrum for their operations. ITU, a specialized agency of the United Nations (UN) is responsible for management of radio spectrum. The radio spectrum is allocated after detailed studies by different Study Groups and thereafter discussions at the World Radio Conferences (WRCs) held every 3-4 years. So far radio spectrum allocated, for IMT applications, are in 800 MHz, 700 MHz, 900 MHz, 1800 MHz, 2 GHz and 3 GHz bands. It may be mentioned that in the aforesaid band (s), more than one ‘radio service’ can operate, and therefore, each application/technologies in a service area of operation (AoO) shall have to limit the number of frequencies to the minimum essential in order to provide a satisfactory existence of other service(s) by applying the latest technical advances and spectrum efficient techniques. The radio spectrum is fuel to more than forty radiocommunication services, to name few are: Mobile, Fixed, Fixed Satellite, Mobile Satellite, Broadcasting, Aeronautical, Maritime, and radio-navigation etc. The applications of RFS can be broadly categorized for: societal (public at large), commercial, security, and safety.

The World Radio Conference (WRC-15) considering the extensive demand of radio frequencies for existing and future wireless technologies, set out among others, relevant Agenda Items for WRC-2019 for future studies required for identification of new and additional harmonized spectrum for IMT, ITS, IoT and Railways for safety/security purposes. 

In this Tutorial, the abovementioned aspects would be discussed in detail. It may be mentioned that WRC-2019 is scheduled to be held during 28 October to 22 November in Egypt. This WRC shall finalize its decisions/recommendations among other issues including on the above stated Agenda Items, which are relevant to this Talk. The outcome of this WRC would be studied/analysed, in two days’ time before start of scheduled 22nd International Symposium on WPMC from 24 to 27 November, and shall be appropriately and accordingly presented in the half-day Tutorial. The Tutorial will discuss and cover about Radio spectrum & its requirements for wide-range of ‘radio services’; ITU & its three sectors; ITU’s Radio Sector, Study Groups, WRC etc, ; radio spectrum management; Role of previous WRCs in allocation of radio spectrum for IMT applications; radio spectrum issues for Industry 4.0, ITS, IoT, UWBs etc; WRC-15 and its relevant resolutions in defining agenda items for WRC-19; Agenda items for WRC-19 and its final outcome on the relevant items.

Toutorial 4 – [Cancelled] Dashboard Design: Applying the Principles of Data Visualization for Business Intelligence and Analytics

ISCTE-IUL, Portugal Elsa Cardoso


In this tutorial the theory and principles of data visualization will be presented applied to the context of Business Intelligence and decision-making. In particular, the tutorial will focus on the design of dashboards for different analytical purposes, including operational and strategic decision support.

Stephen Few (2006) defines a dashboard as a “visual display of the most important information needed to achieve one or more objectives that has been consolidated on a single computer screen so it can be monitored and understood at a glance”. This definition highlights some key aspects of dashboard design. First, dashboards are linked to decision support, providing the appropriate visual displays with the right information (at the right time and with the right context) that enables the decision maker to act upon relevant information. Second, dashboards focus on the most important information, meaning that some options need to be taken at design time, to avoid clutter. Third, dashboards are a type of visualization that needs to be rapidly understood and analyzed by users. Current research and practice on dashboard design promote the use of visual perception principles, which are important to deliver these key aspects. The main challenges of dashboard design are therefore to learn how to stand out the most important information and how to arrange consistently and coherently the layout of a dashboard to efficiently support decisionmaking.

Prior experience in Workshops / tutorials organization:

Elsa Cardoso has organized several workshops and master classes in business intelligence and data visualization.

As leader of the Business Intelligence Task Force of EUNIS – the European University Information Systems organization – she organized several workshops on Learning Analytics for the EUNIS members. In particular, the following contributions were specifically dedicated to data visualization:

– The EUNIS learning analytics workshop: using data to enhance learning and teaching, held at Aalto University Foundation, Helsinki, Finland, 11-12 October 2018. In this workshop she was also responsible for a one-day tutorial on Designing student dashboards. This tutorial was divided into two parts. Part one covered the theory and principles of data visualization and part two was dedicated to hand-on design. Both sessions had around 25 participants.


– A master class (3h) on Data visualization fundamentals for Business Intelligence for the EUNIS Business Intelligence Task Force pre-congress event, that took place at Aristotle University, Thessaloniki, Greece, June 7, 2016.
