The 5G network test station will be built in a French-based space-simulating site of the company Thérèse, but reports point to the need to overcome the major barriers to connecting ground infrastructure to satellites, to ensure that the networks it builds are not expensive, and to eventually receive private and public funding to launch them. It was reported that Ericsson, Thérèse and Hightower had yet to determine the date of launch of their first LEO satellites, but that they wished to be deployed “in the coming years” and that they would seek to acquire a dedicated satellite spectrum for their network. According to the British Financial Times website, in recent days the Swedish telecom manufacturer Ericsson, the French aerospace company Thérèse and the American chip company Hightower have formed a consortium that plans to develop a satellite network to bring 5G into space. It was reported that the consortium was testing a 5G network using LEO satellites to help people access wireless Internet in some of the most extreme terrain and remote areas, and could even be used as a back-up facility for terrestrial networks during power outages or disasters. This could pave the way for global wireless network coverage from space at a time when Governments are increasingly focusing on ensuring the autonomy and elasticity of their telecommunication infrastructure. Korea Financial News, SK Telecom, 21 July, states that the core network of 5G state-of-the-art technologies, such as group acceleration, path optimization and multiple flow control, deployed in cooperation with Ericsson, is officially commercial. The core network provides a rapid response to the surge in on-site addition of communications equipment and traffic through a system-based, light-quantitative approach that significantly improves the efficiency of dispatch and flow processing of new applications on the network. The new core network uses naked metal-based clouds to achieve a 50% improvement in flow-processing efficiency compared to existing physical deployments. The naked metal-based cloud-based technologies are more advanced than the existing virtualization systems, which avoid the duplication of hardware resources and virtual resources on cloud ends, thus allowing systems to be lightly quantified while significantly increasing the speed and service stability of new applications in the communications network. SK telecommunications predicts that in the future cloud-based basic technologies will serve as the basic structure of the 6G core network and will go beyond the existing 5G network technology to become a springboard for the evolution of the 6G network. Japan will select key technologies to advance economic security from nearly 20 fields such as artificial intelligence, biology, etc.
