Topic: Sensors in Aerospace Extreme Environment
Abstract: Extreme environments can threaten aircraft operations whether for military or civilian use or manned/unmanned operations. The range of extreme environments can be wide, and the major challenge of operation is not only able to survive such extreme environments but also to use these as a tactical advantage over adversaries and to own the extreme environments as well.
This keynote will address a challenge list associated with these specific aerospace extreme operational environments include: 1). Degraded visual environment (DVE) of recirculating dust, sand, snow and volcanic ash; 2) In-flight icing encounters presenting a major hazard to safe and efficient operations of both manned and unmanned aircraft; 3). Atmospheric turbulence, gusts and excessive loads (UAV ops); 4) Weather limitations when operating in terrestrial and maritime low altitude environments; 5). Wind limitations for the launch and recovery of small unmanned aircraft, both terrestrial and maritime environments; 6) Precipitation and icing for mid to high altitude operations in tropical convergence areas.
Introductions will be made to the impact of these extreme environments on air vehicle operations, including but not limited to aircraft engines, dynamic system components, and then the role of the sensors in these extreme environments. The mission is to identify candidate technologies that enable aircraft to operate in, and exploit a much wider range of extreme operating environments encountered in current and future missions. There is also a requirement to understand and identify capability gaps and challenges to ensure that candidate technologies are appropriately focused.

Topic: Public Safety Communications above 6 GHz: Challenges and Opportunities
Abstract: Advanced public safety communication (PSC) services call for fast, reliable and low-latency communication technologies, capable of supporting diverse communication modes (aerial, unmanned, vehicular, and peer-to-peer), fast channel dynamics, and ad hoc or mesh structures. For this reason, PSC has been identified as one of the key potential uses cases for the next generation of communication systems, the so-called 5G. In this scenario, the millimeter wave (mmWave) bands and other frequencies above 6 GHz are particularly interesting, since they are largely untapped and offer vastly more spectrum than current cellular allocations in the highly congested bands below 6 GHz, thus enabling orders of magnitude greater data rates and reduced latency. For example, new PSC networks in the mmWave bands could support high-definition video, virtual reality, and other broadband data to large numbers of first responders. Surveillance drones or ambulances could also be provided high-speed connectivity along with machine-type communication for remotely controlled robotic devices entering dangerous areas. However, the way towards this ambitious goal is hindered by a number of open research challenges. In this talk, after a brief introduction to PSC services and requirements, we illustrate the potential of the frequencies above 6 GHz for PSC and discuss the open problems that need to be solved in order to pave this way. Finally, we describe the main components of a test platform for mmWave systems that is functional to the study of such complex scenarios and that we plan to develop as an invaluable tool for realizing mmWave PSC networks.
Biography: Marco Mezzavilla is a Research Scientist at NYU Tandon School of Engineering, where he leads various mmWave-related research projects, mainly focusing on 5G PHY/MAC design. He received the B.Sc. (2007) and the M.Sc. (2010) in Telecommunications Engineering from the University of Padova (Italy), and the Ph.D. (2013) in Information Engineering from the same university. He held visiting research positions at the NEC Network Laboratories in Heidelberg (Germany, 2009), at the Telematics Department at Polytechnic University of Catalonia (UPC) in Barcelona (Spain, 2010) and at Qualcomm Research in San Diego (USA, 2012). He has authored and co-authored multiple papers in conferences, journals and some patent applications. He is serving as reviewer for many IEEE and ACM conferences, journals and magazines. His research interests include design and validation of communication protocols and applications to Fourth-generation (4G) broadband wireless technologies, millimeter wave communications for 5G networks, multimedia traffic optimization, radio resource management, spectrum sharing, convex optimization, cognitive networks and experimental analysis.

Topic: 5G Powerful Engine for the Connected Society
Abstract: Some aspects of 5G are currently being deployed. Soon, there will be wide deployment worldwide. 5G advances wireless communications along three important directions: (1) much faster transmission rate, (2) support for ultra-reliable communications and (3) introducing network slicing. This presentation considers 5G advances from the applications viewpoint. If one wants to summarize 5G in one word, it would be “flexibility”. 5G promises to cover a wide range of data rates from the very low data rate associated with slow data collection over wide areas (e.g. some form of IoT) to the extremely high data rate associated with venues crowded with dense users equipped with advanced devices capable of streaming HD videos and other data intensive applications. It also promises to support high precision and low latency applications (e.g. connected vehicles) and Machine Type communications. The array of known potential applications is very long. The availability of extreme high speed, flexible context-aware networking and ultra-low latency communications would sure trigger the imagination of many entrepreneurs to come up with new and innovative applications. For sure, the next few years, 5G will provide significant boost of the economy, create many new jobs and opportunities. It’s powerful platform for total connectivity and data-driven economy. In this talk, 5G is discussed as new and powerful enabling technology or more precisely a set of new technologies. One of the aim of the talk is to describe the inherent flexibility in 5G and how this flexibility and powerful techniques will enable a new and innovative applications with profound impact on our lives. For example, the core network is being changed considerably through virtualization, virtual machine implementation and network slicing. This will allow different applications to share hardware and infrastructure in a flexible and efficient way. Networks could be built up and teared down at the virtualization level and individual networks could be designed and mapped on the existing infrastructure to fit the specific requirement of the application they serve without compromising quality by catering to average user’s requirements. Different levels of data centers and clouds with different proximities to network cores address latency requirements. Another aspect is the various form of spectrum aggregation toolboxes and algorithms as well as integrating WiFi and cellular capabilities to provide a very dynamic use of the spectrum and allow the use of a very large pieces of spectrum stitched together to support extremely high data rate where and when needed. 5G is still evolving. It will meet our current communications need, making it better and more powerful but more importantly, it is about to enable many new applications that will support an emerging digital economy.
