Abstract: Free space optics (FSO) is a license-free wireless communication technique that has recently received a great attention for a variety of applications. FSO is an attractive solution for last mile connectivity problem
in communication networks particularly when fiber optics installation is costly or unavailable. FSO can also be used to establish inter-buildings/cities secure communications and it can be deployed as a backup to optical fiber networks. Wireless optical communication can guarantee a high-bit-rate line of sight (LoS) transmission over long distances of up to several kilometers. Furthermore, free space communication is considered as a potential technique for scaling down bandwidth challenges in future 5G networks. Multiple wavelength FSO can guarantee better transmission capacities as demonstrated in. Data can be mapped on advanced modulation formats such as quadrature phase-shift keying (QPSK) and quadrature amplitude modulation (QAM) to achieve high bit rates as well as high spectral efficiency levels. Multiple-input and multiple-output (MIMO) FSO communication has also been proposed, whereby multiple lasers are placed to transmit Gaussian beams to multiple receiving apertures.
A possible idea to further increase the capacity of free space wireless optical communication links is to use space division multiplexing (SDM). SDM has been firstly suggested as a potential solution to cope with future bandwidth issues for optical fiber networks and has been also introduced to FSO. The idea is to exploit the spatial structure of the light as an additional degree of freedom for optical communications. In SDM, each spatial mode, from an orthogonal mode basis, can be viewed as an independent data carrier scaling the transmission capacity by several orders of magnitude. A particular mode of choice is the orbital angular momentum (OAM) derived from the Laguerre Gaussian mode basis that have been used to
demonstrate beyond 1 Tbit/s transmission capacity. The goal of this tutorial is to introduce the concept of using OAM carrying light to establish outdoor wireless communication links. The attendees of the tutorial will become familiar with the basics of FSO using structured light beams, challenges and the potential of this technique to provide high-speed outdoor connectivity.

Tutorial 2: Softwarization Concepts and Practice in 5G Communication Systems: SDN, NFV, ICN (3 JUNE, 2019, 13:40h-17:20h)
Speakers: Prof. Fabrizio Granelli (University of Trento, Italy) and Prof. Frank Fitzek (TU Dresden, Germany)
Abstract: A big step lies ahead, when moving from today’s 4G cellular networks to tomorrows 5G network. Today, the network is used for content delivery, e.g. voice, video, data. Tomorrow, the 5G network will be fully softwarized and programmable, with new degrees of freedom.
The aim of the tutorial is to illustrate how the emerging paradigms of Software Defined Networking, Network Function Virtualization, and Information Centric Networking will impact on the development of 5G systems and networks, both from the theoretical/formal as well as from the practical perspective.
The tutorial is split into two major sections: (i) the first one, where the attendees will learn the basics of SDN, NFV and ICN and their application in the framework of 5G (network slicing, mobile edge computing); (ii) the second one, where the attendees will deploy simple yet complete solutions for network slicing and mobile edge computing using their own laptops.
Through the above theory and practice sessions, the attendees will gain useful insights on such emerging aspects in SDN/NFV. Note: Most hands-on sessions will be performed by using virtual machines. For this reason, it is highly recommended to all attendees to install VirtualBox (preferred) or similar VM software before the event.
Additional useful software to download / install before the event:
- Mininet VM + install Flowvisor + Download hands-on Scripts.
- Link to software to use for docker hands-on session.
- Docker software (varies depending on the operating system).
