The research pertaining to non-terrestrial communications has become one of the hottest topics in communications science and attracted researchers’ great attention in recent years Kishk et al. Overall, communications over the aerial layer relying on unconventional infrastructures and apparatuses, e.g., floating balloons, unmanned aerial vehicles (UAVs), and airships, are advantageous compared to both classical terrestrial communications and satellite communications. Such aerial infrastructures can also be utilized to form supplementary networks for emergency communications and other special needs Zeng et al. The much higher aerial base stations (BSs) in the stratosphere than their terrestrial counterparts and the easy-to-deploy nature make stratospheric communications a promising candidate technology for boosting transmission capacity, enlarging coverage, and enhancing network reliability, as well as, finally, democratizing the benefits of information and communications technology (ICT) between urban and rural areas Yaacoub and Alouini (2020) Zhang C. A consensus among the research community is that aerial telecommunication infrastructures will play crucial roles in 6G communications.
Since the end of 2019, researchers in communication sciences have paid great attention to the design of sixth-generation (6G) communication research roadmap Dang et al.
AERIAL COMMUNICATIONS SERIES
Therefore, in this article, we analyze the commercial failure of Project Loon by public information from reliable sources and summarize a series of important lessons for the 6G research roadmap design.
The latent mismatch between academia and industry in communication science should also raise adequate attention. There is no question that the failure of Project Loon will yield profound impacts on and even shift the current 6G research roadmap design. However, the sudden news released in January 2021 that Alphabet is shutting down Project Loon, one of the most important projects enabling communications over aerial infrastructures, surprises the academia of communications science. 2Department of Electrical and Electronic Engineering, University of Bristol, Bristol, United KingdomĬurrently, the sixth-generation (6G) communication research roadmap is being frequently discussed and designed, in which, undoubtedly, aerial telecommunication infrastructures play crucial roles for boosting transmission capacity, enlarging coverage, and democratizing the benefits of information and communications technology (ICT) over the globe.1Computer, Electrical and Mathematical Science and Engineering Division, King Abdullah University of Science and Technology (KAUST), Thuwal, Saudi Arabia.It is also responsible for preparation for studies, planning, construction and development of new civil air navigation systems and infrastructures, their national and international coordination, the management of all rights and obligations of any source and nature, including contracts.ĮNNA has 590 workers – 420 men and 161 women.Liang Zhang 1, Chuanting Zhang 1, Shuping Dang 2 and Basem Shihada 1* 206/19.ĮNNA is tasked with licensing companies, coordinating and supervising activities carried out at airports. The minister praised the change made from ENANA to ENNA-EP, stating that this is a process that needs and should be consolidated.ĮNNA EP, which replaces ENANA, started its activity on July 1, 2019, under the Presidential Decree No. Also read: Angola new regulation for construction and public works projects and inspection The minister also spoke of the installation of digital radios for aeronautical communication, as well as new surveillance systems.Īmong the recommendations, the minister stressed the need to attract new customers, aimed to increase revenues from air navigation fees, as well as the commencement of the training process for professionals with the support of international institutions. He also announced urgent measures such as the interconnection of navigation services, located in airport control towers, via optical fiber, transporting the signal from remote sites to Luanda and vice versa. Speaking at first anniversary of ENNA, Ricardo D’Abreu, who also listed some emergency measures, said the move was part of the modernisation process of the company’s technical and technological means. Angolan minister of Transport Ricardo D’Abreu announced Wednesday the inclusion of fiber optic cable in air navigation services, installation of digital radio and new security systems, as one of the priorities for the National Air Navigation Company (ENNA).
