# Editorial for the Special Issue on Moving Towards 6G Wireless Technologies
###### Abstract  
Fifth-generation (5G) wireless networks have been a key enabler for information societies over the last few years. Now, sixth-generation (6G) wireless networks are under development, and the research community is preparing for the intelligent information societies of 2030 and beyond, targeting even more ambitious performance targets, such as peak data rates from 1 Tb/s, enhanced spectrum and energy efficiency, and extremely low latency communications. This Special Issue of _Future Internet_ titled \"Moving towards 6G Wireless Technologies\" focuses on the design, development, testing, and evaluation of 6G-enabling solutions to meet these ambitious goals. We have published a total of ten papers covering a range of topics including, but not limited to, IoT applications, vehicular networks, 6G-Enabled Internet of Verticals (6G-IoV), and spectrum sharing. In the first paper [1], the authors investigate how the problem of the digital divide, which became clearer in the COVID-19 pandemic, can be mitigated by looking to 6G and other emerging technologies, the latter being not just a mere exploration of more spectra at high-frequency bands but a new paradigm for ubiquitous, pervasive, and high-speed internet connectivity, which can remedy actual limitations in the realization of a truly digital world. Specifically, the authors first introduce several key 6G technologies, such as non-terrestrial networks and Terahertz (THz) frequencies, for bridging the digital gap and then illustrate how these can work in two use cases of particular importance, namely eHealth and education. In [2], the authors encourage further research and development of Unmanned Aerial Vehicle (UAV) flying base station operations, which could also play a significant role in 6G networking. In fact, one of the main goals of 6G networking is reliable connectivity with high-performance communication channels even in rural regions. The authors discuss the unique properties of UAV flying base stations while describing the main properties of its component technologies and functionalities, including traditional telecommunications networking, UAV drones, authentication, and distributed networking. In [3], the authors present HODNET (Heterogeneous on Demand NETwork resource negotiation), an open platform based on the Software-Defined Wireless Network (SDWN) which is able to realize a novel vision to trade and allocate wireless spectra in 6G communication networks inspired by the concept of the sharing economy. Moreover, they analyzed the benefits of the platform with a use case of massive IoT deployment showing a significant improvement in resource utilization with respect to a standard 5G deployment. In [4], the authors discuss how the cloud-to-edge-to-IoT compute continuum can support Search and Rescue (SAR) operations in cases of natural and human disasters. A detailed analysis of current challenges with respect to the technology used in SAR operations is presented with an overview of the advanced solutions that may be adopted in these scenarios. In [5], the authors have reviewed key architecture, networking, and technology components, which are considered critical to the successful expansion of 5G connectivity services and platforms into vertical sectors in the 6G era. While 5G is primarily aimed at the connectivity requirements of specific verticals, such as manufacturing, automotives, and energy, the authors discuss how, in the longer term, the expansion of wide-area cellularconnectivity to these sectors will pave the way for a transformation to a new Internet of Verticals (IoV) in the 6G era, which they call 6G-IoV. They also discuss possible use cases of 6G-IoV, which include distributed and over-the-top cloud manufacturing as a service, the Internet of Robotics (IoR), and the Internet of Smart Energy Grids. In [6], the authors analyze the outage probability expressions for smart Reconfigurable Intelligent Surface (RIS)-assisted Fixed Non-Orthogonal Multiple Access (FNOMA).
