This session will discuss how Open architecture technologies, such as OpenRAN, will be a key enabler of this digital transformation of European economies and societies allowing network operators to source RAN equipment from a more diverse range of general purpose processor hardware, software and radio antennae vendors, each specialising and competing in different parts of the RAN supply chain. OpenRAN also enables networks to be operated in entirely new ways, for example, network automation will drive operational innovation and efficiencies. The fact that the software and hardware layers are disaggregated, brings additional flexibility to network operations, allowing new features and capabilities to be introduced simply via software upgrades, enabling the delivery of flexible high quality services tailored to customers’ specific needs.
Exploiting the frequency ranges above 6 GHz has become a hallmark of modern wireless systems. The use of 20-100 GHz spectrum was a key characteristic of 5G systems, and the 100-500 GHz frequency range will be an important component in 6G. This talk will first discuss the characteristics of wireless propagation channels in those frequency bands, reviewing the fundamentals, and then discussing our recent measurement results in outdoor environments, including ones in the larger than 100 GHz frequency range that show feasibility of high-rate data links at distances up to 100 m in both line-of-sight and many non-line-of-sight situations; yet at the same time these measurements also indicate that many common assumptions about such high-frequency channels, e.g., with respect to sparsity, might not hold under all circumstances. Based on the discussions of the channels, the talk will then investigate single- and multi-user capacity, signaling methods and transceiver structures that are especially suitable for ultra-high data rates at these high frequency bands.
5G rollouts have stimulated new demand that cannot be met by 5G itself. That's where 5G-Advanced comes into play, delivering enhanced capabilities. Without a doubt, 5G-Advanced will further stimulate more new demands that only 6G can address. Looking into these new demands will be crucial to defining 6G. ITU-R is leading the consortium effort to study future technology trend (FTT) and 6G vision, aiming to issue the FTT report and vision recommendation by the end of 2022 and in the middle of 2023, respectively. 6G will go far beyond communications. 6G will serve as a distributed neural network that provides communication links to fuse the physical, cyber, and biological worlds, truly ushering in an era in which everything will be sensed, connected, and intelligent. In addition to connected people and things, we predict that 6G will be the platform for connected intelligence, where the mobile network connects vast amounts of intelligent devices and connects them intelligently. This talk will first start with 5G-advanced as an introduction, then present an overall vision for 6G with drivers, use cases, KPIs, roadmap and key capabilities. Six key capabilities: (1) Extreme connectivity, (2) Native AI, (3) Networked sensing, (4) Integrated Non-terrestrial network, (5) Native trustworthiness and (6) Sustainability, will be further discussed, including potential technologies/research directions and associated challenges.
The new generation of Internet of Things involves Internet of Mobile Things (IoMT) which lets increasingly moving objects make better operational decisions through pooling data and resources from other connected vehicles and devices. Due to the enormous research and commercial potential, a lot of companies and researchers are attracted to this area. This workshop aims to bring researchers working on Future IoMTs under one roof to discuss the implementation, applications, and possible standardization efforts. We expect that the authors can together bring about significant impacts within this domain and share their knowledge and experiences with members of the research community, commercial sector and wider audiences.
As hordes of data-hungry devices challenge its current capabilities, Wi-Fi strikes again with 802.11be, alias Wi-Fi 7. This brand-new amendment promises a (r)evolution of unlicensed wireless connectivity as we know it, unlocking access to gigabit, reliable and low-latency communications, and reinventing manufacturing and social interaction through digital augmentation. More than that, time-sensitive networking protocols are being put forth with the overarching goal of making wireless the new wired. With its standardization process being consolidated, we will provide an updated digest of 802.11be essential features, place the spotlight on some of the must-haves for critical and delay-sensitive applications, and illustrate their benefits through standard-compliant simulations.
At present the O-RAN architecture provides a promising solution of an open-RAN ecosystem, where based on the defined functional splits (CU, DU, RU) a multi-vendor solution can theoretically be achieved. This so called “wave 1.0” 5G that is capable of utilizing only basic (rough) virtualization as well as introducing essential interfaces to enable open-ecosystem, like: E2 for the control of CU/DU/RU as well as A1, O1, O2 for policy based management, network configuration and monitoring. The existing state-of-the art based on IS-Wireless analysis and experiences (also as O-RAN member) should be upgraded to what we call open-RAN Wave 2.0 in order to allow greater flexibility of functional split as well as improve the capability of addressing the challenges of ultra-dense networks. Flexibility of functional splits is essential to adjust open-RAN based networks to the existing infrastructure capabilities including not only fronthaul but also midhaul interfaces. Fronthaul is understood mainly as splits beyond 6 and especially the 7.2 O-RAN split that requires a certain level of capacity, which may be even quadrupled with the split 7.1. In the midhaul e.g. where the CU-CP with RIC (RAN intelligent controller), CORE, MEC and application servers are located, the infrastructure can also vary in capacity. With highly granularized network functions packaged as VNF/CNF (virtual machines of containers) and also providing multitude of split options it is easier to tailor deployment of open-RAN network to fit into available fronthaul and to optimize cost of hardware and network. Moreover, it is then more convenient to orchestrate such “workloads” (i.e. 5G radio stack functions) across edge-cloud continuum, also including edge micro data centers. In this way, multiple split association types can also be achieved naturally e.g. split per slice, per UE, per bearer. The underlying compute resources can also be utilized more efficiently as particular workloads can be fitted to a variety of acceleration cards (GPU, FPGA, SmartNIC) or computer architectures (x86, ARM). Eventually such fine grained, highly composable (orchestrated) disaggregated open-RAN can be called open-RAN Wave 2.0, as it enables achieving higher capacities for network operators who are aiming to address the challenges of ultra-dense networks. Efficient data-driven resource management (both radio and compute) with the novel paradigms like cell-free (or distributed cell-free massive MIMO) are becoming more straightforward to be implemented with such improved open-RAN architectures.
5G and Mobile Private Networks are enabling the digital transformation of manufacturing and the factories of the future. It is essential that network operators build the 5G right so we deliver all key enablers for Private networks in Industry 4.0. This talk reviews the key characteristics of Mobile Private Networks and present real use cases of how companies are now adopting 5G technology to reduce manual processes and enable highly efficient, connected, and flexible factories of the future.
Spain’s 5G players - government, operators, industry — are investing heavily in pilot projects covering virtually every use case. This session will give an overview and highlights of Spain’s first years of 5G consumer deployment and business use cases. We will provide an inside look at pilot case experimentation, exposing lessons learned and comparing deployment in Spain and in other countries in an effort to identify the key ingredients for 5G’s economical and societal success.
In the last few years a variety of players have entered the quantum race, ranging from tech giants - such as IBM and Google – to several small start-up companies, as well as states and governments, with massive public funds to be distributed over the next years. Standardization efforts are already ongoing, such as the one within the Internet Engineering Task Force (IETF). The IEEE has become involved in this effort. Within the context of a real quantum revolution, the vision is to build a quantum network infrastructure, also known as the Quantum Internet, to interconnect remote quantum devices so that quantum communications among them are enabled. We will give an overview about the main challenges and open problems arising in the design of a distributed quantum computing architecture. Quantum computing is on the verge of sparking a paradigm shift. Software reliant on this nascent technology, one rooted in the physical laws of nature, could soon revolutionize computing forever. We will focus on the current quantum computer technology from the hardware and software point of view, providing a detailed roadmap for next years. In this context, specific integration of classical and quantum computing that represents a huge step in accelerating the execution of quantum circuits, or sequences of quantum operations, on real Quantum systems will be described.
6G becomes the hotspot for the wireless research community, whilst the journey to 6G is still many years ahead. The road to 6G entails a process for the fundamental research for 6G technologies, the development of the 6G enabling technologies and standardization of 6G technologies. In this Executive Forum, we will focus on the discussion and debate of the 6G times-line, and route to global standardization on 6G.
Edge computing as an evolution of cloud computing brings application hosting from centralized data centers down to the network edge, closer to consumers and the data generated by applications. It is acknowledged as one of the key pillars for meeting the demanding 5G Key Performance Indicators, especially as far as low latency and bandwidth efficiency are concerned. Moreover edge computing also plays an essential role in the transformation of the telecommunications business, where telecommunications networks are turning into versatile service platforms for industry and other specific customer segments. ETSI ISG MEC is the home of technical standards for edge computing. The group has already published a set of specifications and reports to offer fully standardized solutions to support IoT applications in distributed cloud. The emphasis of this talk is the MEC features in support of IoT use cases and requirements, as well as the MEC integration with 5G system and the MEC expansion to edge federation.
Post-quantum cryptography (PQC) is the cornerstone to build quantum-safe 6G network. This presentation will introduce NIST PQC standardization effort and discuss PQC applications in 6G network security.
We have often spoken of the "flaws" in public policies and regulatory frameworks of states or cities as so many opportunities for imaginative entrepreneurs to create disruptive businesses (think of Airbnb or Uber for example). But the flip side is that much often, these same public policies do not keep pace with the increasingly rapid pace of changing technological innovations or business models in such a way that they constitute a constraint or even a brake on their development. Imagine, just a little, the spaghetti of regulations of all kinds, from local, regional or national authorities, faced by those who want to test, in the public space, a prototype of an autonomous vehicle, for example, in an urban environment. Hell! Our three panelists have had to deal or are currently dealing with this type of context and will share their observations, the lessons they have learned from them as well as some possible solutions, both for those who want to innovate and for public decision-makers.
This workshop provides a venue to bring together standards developers, leading researchers and engineers from government, industry, and academia to present and discuss recent results on shared spectrum technology, and to promote its expedited development.
