In an increasingly interconnected world, satellite communication is presented as a key solution for the expansion of mobile networks to areas where terrestrial installations are unfeasible or complicated. This presentation will address non-terrestrial network technologies and the challenges inherent in satellite communication.
Simulation and testing solutions developed by Rohde & Schwarz will be explored, including specific equipment for network simulation and device evaluation, as well as solutions for satellite channel simulation. Through these innovations, insights will be offered on how to optimize performance and reliability in non-terrestrial communication environments.
This session is designed to provide attendees with a comprehensive understanding of the solutions available to address current challenges in this field.

AI is becoming ubiquitous and Network Services are not exception. In this talk I decribe briefly our efforst to defend AI-based network services from cyber-attacks particulalrly adversarial attacks.
Adversarial attacks are a special type of cyber-attacks that are designed to fool AI-based systems. These attacks are particularly dangerous because they can be used to bypass security mechanisms and cause serious damage. In this talk, I discuss the different types of adversarial attacks that can be used against AI-based network services and the techniques that can be used to defend against them. Particularly, I describe our most recent proposal based on Generative Adversarial Networks (GAN) to filter adversarial attacks in real-time. I also discuss the challenges that need to be addressed in order to effectively defend AI-based network services from adversarial attacks.
Prior to this subject I briefly introduce some of the other work carry on at the cyber-security lab at INOV. Namely, the work on using auto-encoders to detect anomalies in many different systems, the work on the new cryptographic algorithms, and the work on zkSNARKs.

Many applications areas, such as electronics, medicine, as well as aerospace and defense, depend largely on advanced materials with unique properties to design and develop high performance systems. The characterization of these materials is crucial to guarantee their reliability, safety, and effectiveness. 
Network analyzers have become an essential tool for measuring electromagnetic properties of materials, allowing the characterization of their permittivity permeability and conductivity. Its use with dielectric probes allows precise measurements of liquids solids and semi-solid in the frequency range from 10MHz to 1.1THz. We will analyzer the parameters and measurement methods available, comparing advantages and disadvantages of each of them.

We will have equipment available for demonstrations and testing during the event, allowing attendees to see these innovations in action firsthand.

The first two decades of the 21st century have witnessed a boom in the Unmanned Aerial Vehicles (UAVs) market, is all sectors of society, including military, security, industrial and commercial. Irrespective of the specific UAV application area and autonomous capabilities, the communication system constitutes a central piece of the Unmanned Aerial System (UAS).   
During the past few years, INESC INOV has been carrying out both theoretical and applied R\&D in the topic of UAV communications. This talk will present an overview of the main recent and current work.
The use of UAVs as Flying Base Stations (FBS)  to provide communication coverage to ground nodes has been one of the main application areas researched at IST / INESC INOV-Lab. These FBS networks can complement and enhance the land based network infrastructure, or to provide localized coverage in isolated areas. In order to confer elasticity to the FBS network, this usually takes the form of Flying Ad Hoc Network (FANET), in which the FBSs form a mesh network topology, operating as communication relays. One of the main challenges is the mobility of ground devices. This requires the network of FBSs to constantly adapt its topology to provide continuous coverage and the required quality of service. This must be done in a way that is completely transparent to ground devices, thus allowing freedom of movement. Theoretical research has focused adaptation and optimization of the FBS network topology. Applied research has been carried out in the context of European projects, such as H2020 project FASTER, as well as small scale implementations and tests in the context of M.Sc. and Ph.D. theses.
These and other related R\&D research efforts at IST / INESC INOV-Lab will be the focus of this talk.
