Augmented reality user experiences are becoming more available to consumers through a diverse set of devices of various form factors like headsup displays, holographic displays, head mounted devices, and handheld devices. Today, nearly 80% of the world's population uses the compute power and connectivity on their smartphone to access the internet and connect to their network of people and things any time of the day, anywhere in the world. AR and spatial compute technology offer the possibility for users to be presented with additional information of the world (places, things, life) around them proactively without an explicit directed human query. In particular, the possible evolution of optical glasses worn by humans to include AR has the potential of eventually becoming a device of choice by majority users to be their source of infotainment, social connection, education, economy, health and other needs. While there are many issues to be solved to make this potential a reality, in this talk, we will go through some considerations and challenges to be met by technologists to make AR glasses a platform for users to enjoy AR experiences ubiquitously. We will explore various system-level optimizations that need to be done to deliver an intuitive, immersive, always-on AR experience everywhere. These system-level optimizations would include power consumption considerations on the AR glasses plus the connections to any companion devices on person and to the cloud where ultimately most of the information needed by the user lies.
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.
In the recent years, the need for high QoS Internet services along with increasing data traffic has increased and led to bandwidth scarcity in the radio-frequency (RF) spectrum. One of the solutions to this problem is the use of Visible Light Communications (VLC). Visible Light Communications is a declination of the broader wireless optical paradigm that embraces also infra-red and ultra-violet. Recently we have seen deployment of Li-Fi (Light-fidelity) which has emerged as an innovative technology for indoor wireless by starting to augment typical RF-based systems. But eventually we expect it will replace conventional Wi-Fi access in many scenarios. Li-Fi, and VLC more generally is capable of providing multiple services like illumination, data transmission and localization at the same time making it a suitable technology for the smart environments driving the evolution towards the 6G Era. VLC has been enabled by the development of suitable light emitting diodes (LEDs) as incoherent solid state lighting sources employable for both illumination and data transmission. At the receiver side, the optical signal is collected by a photodiode (PD) and converted into a current that is further processed in order to detect information. The small size of optoelectronic hardware allows the implementation of dense multi-LED transmitters, in the form of an array or matrix at the access point, while within the portable user equipment there is a need for small device, leading to miniaturization and a reduced number of receiving elements. The engineering and communications challenges underlying these technologies will be described in some detail. Another paradigm, known as camera communication, utilizes smartphone cameras as receivers in order to provide access to general purpose devices and this will be described and discussed. Visible Light Communications is a new technology with some commonality to traditional radio frequency solutions as well as techniques that until now were specifically developed for optical wireless systems. We will outline the field of application of VLC which is very broad with uses in situations where RF may be less suitable or unsuitable such as airplanes systems, hospital environments etc. We will also describe the inherent security advantages of VLC which is able to grant an optical secrecy level in which eavesdroppers must be within a few squared meters of the user to mount a possible attack.
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.
TCP/IP is not secure, a fundamental change is required. One owner environments (VPN and firewalls) do not support shared operations and devices. This presentation will examine the fundamental weaknesses of TCP/IP and why can we not fix the existing infrastructure. Also, what will be the protocol requirements for TCP/IP replacement taking into account security and efficiency considerations and how digital rights can be defined, managed and protected.
Barely seen in action movies until a decade ago, the progressive blending of UAVs into our daily lives will greatly impact labor and leisure activities alike. Most stakeholders regard reliable connectivity as a must-have for the UAV ecosystem to thrive, and the wireless research community has been rolling up its sleeves to drive a native and long-lasting support for UAVs in 5G and beyond. Moving up, the recent introduction of more affordable insertions into the low orbit is luring new players to the space race, making a marriage between the satellite and cellular industries more likely than ever. In this talk, we will navigate from 5G to 6G use cases, requirements, and enablers involving aerial and spaceborne communications, also acting as a catalyst for much-needed new research.
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.
Research activities in academia and industry worldwide towards the 6th generation (6G) mobile communication system have recently considerably gained momentum. In this overview we will highlight the anticipated 6G timeline and technology concepts which have to fulfil even more stringent requirements in comparison to 5G, such as ultra-high data rates, energy efficiency, global coverage and connectivity as well as extremely high reliability and low latency. One of the 6G technologies are sub-Terahertz and terahertz (THz) waves which have frequencies extending from 0.1 THz up to 10 THz and fall in the spectral region between microwave and optical waves. The prospect of offering large contiguous frequency bands to meet the demand for highest data transfer rates up to the terabit/sec range make it a key research area of 6G mobile communication. These efforts require an interdisciplinary approach, with close interaction of high-frequency semiconductor technology for RF electronics but also including alternative approaches using photonic technologies. The THz region also shows great promise for many applications areas ranging from imaging to spectroscopy and sensing. To fully exploit the potential of this frequency range it is also crucial to understand the propagation characteristics for the development of the future communication standards by performing channel measurements. We will highlight the characteristics of channel propagation in this frequency region and present new results from channel measurements at 158 GHz and 300 GHz.
Sitting at the intersection of wireless communication and ML, the talk will focus on two important aspects of wireless edge AI. First, we will discuss and demonstrate the application of ML in wireless communication for understanding, orchestrating, securing and maximizing the use of spectrum resources through learning. ML techniques can provide significant leaps in performance and efficiency of key L1 functions surrounding channel sensing, channel modeling, modulation and receiver design, and spatial re-use, as well as improving access and coordination schemes. We will explore how some of these ideas are advancing the 5G RAN today and how they can evolve to enable 6G.Second, we describe the role of Distributed Edge AI in the wireless environment. Owing to the distributed nature of data arising from sensors, base stations, and so forth, the goal in edge AI is to train privacy-preserving machine learning models under resource constraints. We provide an overview of recent techniques such as federated learning, distillation and split learning. We will also explore how to harness over-the-air computing and analog communication to provide scalable and privacy-preserving over-the-air model training. The talk will conclude by shedding light onto the next frontier of edge AI sitting at the confluence of semantic communication and ML.
This session will discuss the evolution of radio access network to open and virtualized cloud native RAN. It will focus on the RAN networks today for 5G, current ecosystem landscape, emerging trends in this space for 5G and beyond. It will also talk about the opportunities and challenges as well as how our network will become scalable specifically in the context of virtualization. The session with discussion some of evolving trends towards 6G and how cloud native technologies and ubiquitous computing will play a crucial role going forward. Why is this topic important: Analysts are getting more bullish on ORAN/vRAN – Dell ORO recently increased the ORAN/vRAN adoption from 10 to 14% by 2025. There are lot of innovations and investments being done in both hardware and software associated with ORAN/VRAN. Multiple partnerships/consortiums are being formed across the RAN ecosystem. The usage will also extend from Macro network to enterprise & IOT networks as well. What industry challenges are you addressing / solving? This will address dynamic scalability of a network and availability of multiple ecosystem options that will deliver TCO benefits for the end customer.
Spectrum regulation challenges grow for both unlicensed (e.g., Wi-Fi) and licensed (e.g., cellular) opportunities, particularly those created by 10's to 100's of billions of connected, communicating devices. Dynamic, cognitive solutions just begin to find field use and initiate the inevitable march towards increasingly artificially intelligent allocation of spectra and space. This talk reviews some multiuser fundamentals, their complexity of solution, and how they may find future application to magnify spectral efficiency by orders of magnitude.
Today, channel codes are among the fundamental parts of any communication system, including cellular, WiFi, and deep space, among others, enabling reliable communications in the presence of noise. Decades of research have led to breakthrough inventions of various families of channel codes. Yet no unified approach exists in answering these two fundamental questions: Given a channel, how do we efficiently construct the best possible code? And given a channel code, how do we design an efficient and optimal decoder? In this talk, we will discuss how the remarkable advancements in data-driven machine learning (ML) can be leveraged toward answering these questions. In particular, we will focus on a class of codes rooting in Plotkin recursive construction. This class includes Reed–Muller (RM) codes as the state-of-the art binary algebraic codes, as well as polar codes, the first capacity-achieving codes with explicit, i.e., non-randomized, constructions. In the first part of this talk, we will present an efficient and close-to-optimal decoder obtained for RM codes by learning a pruning process applied to an exponentially complex decoder. In the second part, we will tackle the fundamental problem of designing new channel codes. In particular, we will demonstrate KO codes, a new class of channel codes designed by training neural networks while preserving Plotkin-like structures. KO codes beat both of their RM and polar code counterparts, under the successive cancellation decoding, in the challenging short-to-medium blocklength regime. We will also discuss various challenges that should be overcome to pave the way for adopting such ML-aided channel coding strategies in practice.
Edge devices collect massive amounts of data, opening up new potentials for machine learning applications. Machine learning at the edge can benefit from exploiting both data and processing power distributed across many wireless devices, but this brings about many new challenges including the low latency requirements of learning applications, privacy concerns preventing data sharing, and the impact of noise and interference on the convergence of the learning process. Overcoming these challenges while meeting the requirements of the machine learning tasks calls for a new paradigm of semantic-oriented communication network design tailored for learning applications. In this talk, I will present recent results on efficient distributed inference and training over wireless networks taking into account channel impairments and power and bandwidth limitations of wireless devices, as well as the semantics of the underlying learning tasks. This will involve bringing together novel communication and coding techniques with distributed learning and inference algorithms.
As Wi-Fi "strikes again" with 802.11be, this forum will host a discussion on its evolution, the ongoing 802.11be standardization, the opportunities created by the progressive adoption of the 6 GHz spectrum, and the increased interest in supporting not only higher capacity but also reliable and low latency applications using Wi-Fi. Experts from industry and academia will share their experience in driving standard and product development, spectrum and technology regulations, and research visions.
A burgeoning second quantum revolution promises powerful applications of quantum mechanical phenomena discovered and understood throughout the last century. While the biggest impacts seem confined to an undetermined future time frame, some quantum technologies are achieving maturation. We ask a panel of experts about the current and near-term applications of quantum technologies in information and sensing.
