The role of ICT and wireless communications is critical in realizing the twin transition of green and digital. The wireless and mobile communications community has taken sustainability as the key goal driving the whole R&D of the next generation of mobile communication networks (6G) aiming at deployment in 2030s. Understanding the triple bottom line of economic, social and environmental sustainability together with the concrete United Nations Sustainable Development Goals (UN SDGs) with specific targets and indicators are fundamental for 6G R&D but their linkages are not yet clear. This paper investigates sustainability and sustainable development in the context of 6G. A special focus is on the management of the fundamental natural resource for wireless communications, namely the radio spectrum whose management keeps getting ever more complex. The paper highlights the role of new sharing-based spectrum governance models, to rapidly respond to the needs of the changing world towards a sustainable future.","PeriodicalId":423554,"journal":{"name":"2021 ITU Kaleidoscope: Connecting Physical and Virtual Worlds (ITU K)","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121741968","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This has been accompanied by the formation of active smart city epistemic communities and advocacy coalitions, the insertion of a new cadre of smart city professionals into city administrations, an extensive apparatus of social learning, and numerous funding mechanisms to facilitate uptake. It is clear from the plethora of initiatives underway globally that the idea and ideals of smart cities is quite broadly conceived. Critically, in all cases, digital technologies are front-and-center as a vital ingredient for addressing the major issues facing city managers, businesses, and citizens. Core technologies include city operating systems, performance management systems, centralized control rooms, digitally mediated surveillance, intelligent transport systems, smart grids, predictive policing, sensor networks, building management systems, and civic apps. While these technologies offer solutions to urban problems, they also raise a number of concerns relating to surveillance, dataveillance and privacy, predictive profiling, social sorting and redlining, anticipatory governance and nudging, and control creep and security. Along with three other key issues, these concerns mean that while smart cities are in the process of being created their formation has been slow and piecemeal, and in most cases a smart city vision has only partially been embedded within city administrations or been greeted with apathy or resistance. In other words, an adoption gap has developed with city administrations proceeding cautiously with smart city initiatives. This gap is significant enough that some enthusiastic, early corporate promoters of smart cities have pivoted their endeavors into other related markets. This paper explores this adoption gap examining four sets of factors that have stymied their rollout and considering whether smart city standards might be a means of narrowing the gap.","PeriodicalId":423554,"journal":{"name":"2021 ITU Kaleidoscope: Connecting Physical and Virtual Worlds (ITU K)","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133306373","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For such a purpose we built a mixed-reality, multi-user platform, which we named Aroaro and can be deployed on different virtual reality and augmented reality devices. In Aroaro, users can experience data visualization, either individually or as part of a team. With a set of lab tasks designed to lead lab subjects to analyze the network information while immersing into the rich virtual environment, our approach belongs to the nascent area of immersive analytics. We assume a business unit has already procured some network data set and been tasked with problems that need to reveal information about the network's connectivity properties. This paper is concerned with how a business unit achieves problem solving (decisionmaking) when relying on immersive analytics. Our approach combines a high-quality virtual environment such as Aroaro, its data visualization engine and the analytics afforded by concepts of network centrality in a network. We report on preliminary results of having lab subjects experience two visualization environments: a 3D visualization system on a 2D-flat screen and our mixed-reality, multi-user platform for network data visualization.","PeriodicalId":423554,"journal":{"name":"2021 ITU Kaleidoscope: Connecting Physical and Virtual Worlds (ITU K)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116494470","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In a Beyond 5G mobile networks, connectivity to the network with sufficient quality should always be provided to users who demand that various quality requirements be met anytime and anywhere in the physical space. To achieve this, it is necessary to eliminate the degradation of radio quality at the cell edge, which requires the installation and cooperation of a much larger number of base stations in higher density. Furthermore, to overcome the imbalance in communication quality between the uplink and downlink still found in 5G, it is also necessary to eliminate the limitation of user terminals by virtually increasing the number of antennas and expanding transmission power for the number of antennas of user terminals and the power consumption of user terminals. On the other hand, a new RAN management is expected to provide users with their respective radio access capability through flexible cooperation of the base station around them. In this paper, we describe in detail the specific technical issues and our approach to realize the user-centric RAN architecture.","PeriodicalId":423554,"journal":{"name":"2021 ITU Kaleidoscope: Connecting Physical and Virtual Worlds (ITU K)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128894270","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
