Narrowband Communication What can narrowband communication do?

Matthias Herlich von Salzburg Research leitet das Tutorial »Introduction to Narrowband-Communication« beim Wireles Congress 2018.
Matthias Herlich, Salzburg Research, gives the Tutorial »Introduction to Narrowband-Communication« at the Wireles Congress 2018.

Five questions for Matthias Herlich from Salzburg Research on his tutorial »Introduction to Narrowband Communication« at the 15th Wireless Congress 2018 on 15 November in Munich.

At the 15th Wireless Congress Matthias Herlich and Ferdinand von Tüllenburg, both working at Salzburg Research Forschungsgesellschaft m.b.H., will take a closer look at the different radio technologies of narrowband communication. With their tutorial »Introduction to Narrowband Communication« on November 15, 2018, they provide assistance in selecting the radio technology best suited for an application.


?   Herr Herlich, what is Narrowband-Communication?

!   Matthias Herlich: Narrowband-Communication is a set of communication technologies that use a very small frequency spectrum. Thus, they cannot provide high data rates, but are optimized for long range and low energy consumption. Additionally, they promise improved obstacle penetration (such as building walls).


?   What challenges does Narrowband-Communication impose for developers?

!   Herlich: Today developers are used to ubiquitous broadband Internet. However, using Narrowband-Communication requires to send as few bits and as rarely as possible.


?   Which wireless technologies do you focus on and for which applications have they been developed?

!   Herlich: In our tutorial we – the tutorial will run in cooperation with my colleague Ferdinand von Tüllenburg – will focus on the most widely considered narrowband technologies, namely: LoRa, Sigfox and NB-IoT. However, we will also compare them to other technologies, such as WiFi, LTE and NFC. We will give a broad overview of possible applications for narrowband technologies, but based on the capabilities of narrowband technologies, we focus on low data rate use cases.


?   How can I choose the right wireless technology for Narrowband-Communication?

!   Herlich: The right narrowband technology depends heavily on the requirements of the application. A very important question for this selection is: Where is the technology going to be used? Depending on whether the answer is worldwide, in a single city or on a mountain pasture, other technologies will be better suited.


?   What will you show in your tutorial at Wireless Congress 2018 and who are you addressing?

!   Herlich: In this tutorial, we will:

1. give an overview of innovative applications based on narrowband technologies,

2. provide a classification of the most important wireless (narrowband) communication technologies,

3. describe the implementation of a simple application and the differences in the implementations using LoRa, Sigfox and NB-IoT,

4. demonstrate object localization, and

5. show an interactive online tool that helps to select a wireless (narrowband) communication technology.

We target decision makers and developers, which have to select a wireless communication technology, but are overwhelmed by the available information about the technologies.

Matthias Herlich

is a researcher in the advanced networking center at Salzburg Research. In the past he worked on radio access networks, software-defined networking, wireless sensor networks, and communication networks for smart grids.

Matthias has experience with analytic and simulation-based approaches as well as evaluation of measurements. He studied computer science at the Universität Paderborn – in the computer networks group – and worked at Palo Alto Research Center and the National Institute of Informatics in Tokyo before coming to Salzburg Research. Currently, Matthias focuses on reliability of wireless networks.


Dipl.-Inf.(FH) Ferdinand von Tüllenburg, M. Sc.

received his first academic degree Dipl.-Inf.(FH) from the Department of Computer Science and Mathematics at the University of Applied Sciences of Regensburg and his MSc degree from the Department of Computer Science and Mathematics at the University of Passau.

He worked as technical consultant and software engineer for several companies and institutions. Since 2013 he is a member of the Advanced Networking Center at Salzburg Research. He coauthored multiple publications and contributed to several international research projects.

His research interests are distributed and multi-agent systems, especially in the context of Smart Grids, and future data communication systems using software-defined networking and network function virtualization. In recent projects, he could gain extensive experience in (co-)simulation in the context of network communication in power systems. An area of interest recently added is the application of machine learning concepts in the fields stated above. Since 2015 he is a member of the ETSI Industry Specification Group for Network Function Virtualisation (ETSI NFV-ISG). Ferdinand is an IPMA certified project manager.
