11. Concluding Remarks
In recent years, technologies for direct wireless connection between machines, such as between industrial devices or self-driving cars, has attracted much attention.  Standardization and technology developments for machine-type communications are also underway for 5G and wireless LAN systems. In machine-type communications, unlike high data rate communications, high reliability, small jitter characteristics, low cost, and low power consumption are important characteristics. This workshop was aimed to present and discuss latest research and development activities on machine type communications towards standardization and practical applications for industrial use by researchers who are active at the forefront. We deeply discussed on wide aspects of the technological subjects, bottlenecks, solutions, and practical timelines in relation to the presentations given by four renowned leading researchers and questions to deepen our common understanding of prospects.
Dr. Satoko Itaya (NICT) talked about the applications of wireless communications at manufacturing sites, especially about the issues specific to manufacturing sites and the problems of using commercially available wireless devices. She also introduced Flexible Factory Project, a project to use wireless communications in manufacturing. Dr. Haruki Ikeda (ABIT Corporation) introduced the local 5G system developed by his company and its application experiments to smart factories, especially for vehicle base operations, remote heavy machinery operations, experiments at a baseball stadium, and smart city demonstration experiments. He also explained the development status of post-5G semiconductor chips for ultra-low latency.

Dr. Yuji Aburakawa (NTT DOCOMO) explained the case studies of 5G solution co-creation projects. He also introduced 5G application experiments for use cases such as remote automated driving, remote operation of large construction machinery, telemedicine, and remote surgical support. He also gave an outlook on the technological development of 6G.
 Dr. Tetsuya Yamamoto (Panasonic) spoke about the standardization issues of Industrial IoT/URLLC in 3GPP. He explained the issues to be considered in each release and reviewed the status of Industrial IoT/URLLC in those releases. In addition, he introduced the transmission technology to realize low latency and its numerical evaluation results.
All the speakers presented the results of the latest studies for practical use. Also the issues to be solved and the prospects for the industrial application of wireless communications were discussed in depth. This workshop was very useful to introduce the results of the latest demonstration experiments and to share the issues specific to machine-type communications with the participants since machine-type communication has become a major subject of discussion in the standardization bodies.
