Presentation:  The new technologies in the global scenario and its impact in today’s knowledge society: an ITU perspective. 
Abstract: ITU, the United Nations specialized agency for ICTs and telecommunications, is committed to playing a leading role in the development of the digital economy through extending the benefits of advances in technologies and embracing the opportunities it unleashes. The three ITU sectors – Radiocommunication, Standardization and Development – are working together to meet these challenges and the collective success will be a key factor in ensuring the provision of equitable opportunities access to the technology throughout the world. This session is dedicated to providing an overview of ITU, its role and mandate as a Specialized Agency of United Nations and its core activities undertaken in the fields of Radiocommunication, Standardization and Development of ICTs. The reviewing of ITU activities will consider among others the 150 Anniversary of ITU, Regional Initiatives for the Americas and World Radiocommunication Conference. Emphasizing how new technologies are part of the global scenario and its impact in today’s knowledge society, such as the Internet of things and 5G networks.

Presentation: Compressive Wideband Spectrum Sensing for Wireless Cognitive Radios 
Abstract: Compressive sensing is one of the recent eminent advances in signal processing and statistical learning, with impact to various applications including data sciences, communications, sensor networks, bioinformatics, and medical imaging. It requires information-bearing signals to be sparse over known domains, either naturally or by design. In this talk, I will introduce the fresh notion of compressive covariance sensing, and advocate its exciting implications for (cyclo) stationary processes characterized by second-order statistical descriptors. Such descriptors include (periodic) covariances or frequency, cyclic, angular and Doppler spectra, which already effect signal compression even in the absence of sparsity. Using this key observation, we will demonstrate how the attribute of sparsity can be leveraged more effectively, or, even bypassed when recovering the second-order statistical information of interest. As a leitmotif, we will use the task of wideband spectrum sensing for wireless cognitive radio, which is instrumental for realizing the goal of enhancing access to the radio spectrum. We will present a cyclic feature based compressive spectrum sensing approach for wideband cognitive radios. Using the new framework of compressive covariance sensing, wideband weak signals can be sensed reliably from sub-Nyquist-rate samples in the presence of noise uncertainty, even for (non-sparse) crowded spectrum.

Presentation: Tripping the Light Fantastic: Optical Wireless Communications. 
Abstract: For the past fifteen years, wireless local area networks have operated successfully in the 2.4 GHz band and the 5 GHz bands. Signals from these bands do not confine themselves to a given room or even household, so security and frequency re-use are issues for concern. Alternative frequencies such as 60 GHz or optical wireless links are currently being investigated as alternatives to these leaky lower bands. Optical wireless transmission will use available room light to send information. This future technology will allow existing light to do double-duty as information-bearing signals. This talk will focus on the benefits and challenges of optical wireless communications.

Presentation: Management of SDN- and NFV-based Computer Networks. 
Abstract: The paradigms of Software-Defined Networking (SDN) and Network Functions Virtualization (NFV) have revolutionized the computer network industry. The widely recognized benefits achieved by employing SDN and NFV include the easy introduction of new functions in the network (i.e. Firewalls and NAT), independency of device vendors, and lower cost of deployment and maintenance. However, as in every new technology, novel management functionalities, previously absent, are now required. In the case of SDN and NFV, the some management challenges include: mapping of virtual machines into physical hardware, determining the network path which the flows of interest have been through, the load balance and number of instances in critical servers. Often, the management aspects are neglected in the design of new networking technologies. NFV and SDN are not exceptions. In this presentation, SDN and NFV will be reviewed, while the main managements requirements will be identified. Also, the main contributions from academia and industry that address these requirements will be discussed. In this process, the open issues and challenges will be mapped, opening new opportunities for research and development in industry and academia alike.
