The joint proposal of the research and development team consisting of Broadband Tower Co., Ltd., Panasonic Semiconductor Solutions Co., Ltd., Nippon Telegraph and Telephone Corporation, Tokyo Institute of Technology, National Research and Development Corporation Information and Communication Research Organization, Nagoya University, Tokyo University, and Nagoya Institute of Technology is the general affairs. It was adopted by the Ministry of Internal Affairs and Communications as a research and development project for expanding radio resources in 30.
Research and development for expanding radio wave resources is being carried out by the Ministry of Internal Affairs and Communications with the aim of alleviating the tight frequency situation and effectively using radio waves in order to respond to the growing needs for new radio wave usage.Six R & D issues were solicited in FY30, and this joint R & D team is working on the R & D issue "Research and development on basic technology for the spread and deployment of 6G", which is the technical issue "Lower power consumption of base stations".・ Work to establish "millimeter wave band base station configuration technology that realizes miniaturization".
It is said that 5G, which is a next-generation communication technology, will begin to spread and deploy in earnest from 2020, and 5G base stations are required to be arranged and ensure performance in consideration of the usage pattern and the characteristics of its frequency.In order to achieve a certain level of coverage, it is necessary to increase the output of the base station, densely and flexibly arrange it, and it is said that the issues are to reduce the size and weight of the base station and reduce the power consumption. ..
This team believes that it is effective to increase the output and efficiency of amplifiers, which are the main components of base stations, and to establish excellent mass production methods, and comprehensively develop device technology, circuit technology, mounting technology, etc. that lead to this. Proposed as a solution.The team also includes Professor Hiroshi Amano of Nagoya University, who won the Nobel Prize in Physics in 2014 and has global knowledge in gallium nitride research and development, and is expected to research and develop for 5G innovation. ..
