Wireless Communication Technologies in 5G and 6G

Dear Colleagues,

Fifth-generation (5G) mobile technology is expected to be operational by 2020 and is currently attracting extensive research interest from both industry and academia, with a specific focus on its opportunities and challenges, as well as the research developments which are enabling 5G technology. This is particularly important as, with 5G technology only just now being rolled out, work has already begun on the sixth-generation (6G) standard. In March 2019, a global 6G Summit event was held in Finland, and 6G is expected to bring forth a great revolution in communication technologies as it will enable the Internet of Everything. Compared with 5G technology, the future 6G technology is expected to allow even higher throughputs, even shorter latency times, greater component density, and the mass integration of artificial intelligence in all segments constituting the network.

As we move toward next-generation 6G mobile radio, many challenges will need to be fully mastered concerning individual components and their interactions. There are four research areas in 6G: wireless connectivity, devices and circuit technology, distributed computing, and services and applications.

This Special Issue encourages high-quality papers that advance the state of the art and practical applications of future 6G technologies. This feature topic will bring together academic and industrial researchers to identify and discuss the significant opportunities and challenges in applying 6G technologies to the understanding and design of modern network systems.

Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Energies is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs).
