The ComSoc Portuguese Chapter is involved in several ways in conferences, talks, lectures or other events that join the portuguese scientific community working in the vast area of Communications.
(27/9/2017) Prof. Sumit Roy Distinguished Lecture
This talk presented an overview of current research that thematically centers around Spectrum Sharing – a topic whose importance has been ratcheted by the Jun 2010 U.S. Presidential Memorandum (https://www.whitehouse.gov/the-press-office/presidential-memorandum-unleashing-wireless-broadband-revolution) to “make available a total of 500 MHz of Federal and nonfederal spectrum over the next 10 years, suitable for both mobile and fixed wireless broadband use”. The first down payment on the above is the current AWS-3 transition (https://www.ntia.doc.gov/category/aws-3-transition) of 50 MHz of spectrum that will require spectral coordination between numerous Federal incumbents (radar, navigation etc.) and cellular operator networks (notably, 4G LTE and WiFi).
Spectrum Mapping using Wide Area RF Software Defined Radio/Sensors
The need for more efficient spectrum use has led to notion of Dynamic Spectrum Access (DSA) whereby secondary (unlicensed) users are permitted to use some bands on a `non-interfering’ basis with the primary (licensed) users (e.g. TV White Spaces). This in turn has resulted in database centric architectural solutions (to ensure the desired protection to the licensed incumbent) with the recognition that wide-area distributed spectrum sensing using fixed (and in future mobile crowdsourced) spectrum sensors could be an integral component of such systems. The talk will describe recent work on developing low-cost distributed spectrum monitoring infrastructure.
Link Layer Enablers for Spectral Co-existence: Radar/Wi-Fi & LTE
Effective spectrum sharing will rely on new ideas and effective tools for modeling and analysis of spectral co-existence between dis-similar systems. UW team has developed a suite of analytical and simulation approaches to explore co-existence between co-located Federal (e.g various types of radars) and civilian communication systems, at both the link and network levels. These include, necessarily balancing two conflicting goals: ensuring that the cumulative impact of civilian communication technologies (such as cellular LTE and WiFi networks) fall within incumbent protection guidelines as required, while simultaneously quantifying the impact of radar interference on such network throughput. This part of the talk will describe some recent results on link layer co-existence mechanisms between a search radar and Wi-Fi networks.
Sumit Roy received the B. Tech. degree from the Indian Institute of Technology (Kanpur) in 1983, and the M. S. and Ph. D. degrees from the University of California (Santa Barbara), all in Electrical Engineering in 1985 and 1988 respectively, as well as an M. A. in Statistics and Applied Probability in 1988. Presently he is Integrated Systems Professor of Electrical Engineering, Univ. of Washington where his research interests include fundamental analysis/design of wireless communication and sensor network systems spanning a diversity of technologies and system application areas: next-gen wireless LANs and beyond 4G cellular networks, heterogeneous network coexistence, spectrum sharing, white space networking and software defined radio platforms, vehicular and underwater networks, smart grids and RFID sensor networking.

5th January, 2016, 16h30 -Instituto de Telecomunicações, Universidade de Aveiro
We are pleased to announce the presence of the distinguished lecturer, Prof. Dr.-Ing. Stefan Wesner, who visited us at the Instituto de Telecomunicações, in the Universidade de Aveiro Campus. The title of the presentation was:
“BelWü – A High Speed Network Supporting a State Wide Secure Cloud Infrastructure”
The region of Baden-Württemberg operates its own dark fibre based research network currently connecting 9 universities, more than 40 universities of applied sciences and other non-profit organisations such as cultural institutions or schools between each other and to the Internet. BelWü has just completed a major upgrade of its optical infrastructure from a static optical network towards a dynamic and flexible ROADM based solution and will upgrade its IP layer accordingly connecting the universities with redundant 100Gbps.
The network evolution is driven by a regional service provision concept across the universities supporting cross-organisational services such as compute clouds, long term archiving, high performance computing services but also common IT services such as the library management system.
Technology choices and challenges with a 100Gbps connectivity have been investigated within the bwNET100G+ and bwCloud Projects bringing together the network operation centre of BelWü, the computing centres of the nine universities and researchers in the region specialised in relevant fields such as high speed transport protocols, security solutions at high speeds, software defined networking and Cloud computing.
This talk will outline the technological evolution of BelWü in 2017 and how the regional service provision (using bwCloud as an example) and technology evaluation projects such as bwNET100G+ supported technological choices.
Prof. Dr.-Ing. Stefan Wesner is the director of the Communication and Information Centre (KIZ) and the institute for Organisation and Management of Information systems (OMI) of the University of Ulm. Furthermore, he is the scientific chairman of the research network ISP connecting the 9 state universities and 40 applied research schools in the region. He has been actively participating in research projects on national and international level since 1997, focusing in particular on distributed systems and improving programmability and usability of large scale systems.
His research interests are currently focused on intelligent and adaptive execution environments for next generation of Cloud infrastructure systems. This covers in particular Multi-Cloud solutions and integration of Cloud and Software Defined Networking in wide area networks. Furthermore his group is working on efficient programming of heterogeneous computing systems.

Distinguished Speech by Dr. Tarik Taleb (06-06-2016)
This past 6th of July, the Instituto de Telecomunicações, at the Universidade de Aveiro in Portugal, had the pleasure of hosting a Distinguished Speech by Dr. Tarik Taleb from Aalto University, Finland, with the title “Towards 5G: On Network Softwarisation”. The talk was very interesting and addressed key concepts of the upcoming 5G network architecture.
More on the talk: “Towards 5G: On Network Softwarisation”
The telecom industry keeps reinventing itself. Soon, the world will be experiencing the 5th generation mobile networks (5G), also referred to as beyond 2020 mobile communication systems. Major obstacles to overcome in 5G systems are principally the highly centralized architecture of mobile networks along with the static provisioning and configuration of network nodes built on dedicated hardware components. This has resulted in lack of elasticity and flexibility in deployment of mobile networks; rendering their run-time management costly, cumbersome and time-consuming. Software Defined Networking, Network Function Virtualization, and Cloud Computing, along with the principles of the latter in terms of service elasticity, on-demand features, and pay-per-use, could be important enablers for various mobile network enhancements, to specifically virtualize and decentralize mobile networks using general-purpose COTS (commercial of the shelf) hardware. For this purpose, different requirements have to be met and numerous associated challenges have to be subsequently tackled. This talk will touch upon the recent trends the mobile telecommunications market is experiencing and discuss the challenges these trends are representing to mobile network operators. To cope with these trends, the talk will then showcase the feasibility of on-demand creation of cloud-based elastic mobile networks, along with their lifecycle management. The talk will introduce a set of technologies and key architectural elements to realize such vision, turning end-to-end mobile networking into software engineering.
