(MENAFN- JCN NewsWire) ">Fujitsu develops pioneering millimeter-wave chip technology for 5G radio units
Multibeam multiplexing technology enables high-speed, high-capacitymunications over 10Gbps and reduces powernsumption by 30%

TOKYO, Aug 28, 2023 - (JCN Newswire) - Fujitsu Limited announced the development of a new millimeter-wave chip for 5G that supports multibeam multiplexing (excluding polarization multiplexing (1)), enabling up to four beams to be multiplexed by a single millimeter-wave chip for the radio units (RU) of 5G base stations. The development was undertaken as part of the "Research and Development Project of the Enhanced Infrastructures for Post-5G (2) Information andmunication Systems" (3)missioned by Japan's New Energy and Intrial Technology Developmentanization (NEDO).

Withnventional technologies, a single millimeter-wave chip ised to generate a single beam, resulting in larger and increased powernsumption. When the newly developed technology is applied to actual base stations, Fujitsu demonstrated that it is possible to achieve high speed and high capacitymunications of 10Gbps or more with a half the size of anventional RU. This allows for systems with fewer millimeter-wave chips, which ultimately leads to reductions in powernsumption per RU by 30%.
Project Background
5Gwork technologies are expected to achieve higher speeds and capacity by effectively utilizing wireless resources in the millimeter-wave band. While this approach offers the potential to significantly improvemunications speed and capacity, millimeter and other high-frequency radio waves tend to be blocked by obstacles, making it difficult tomunicate between great distances. One possible approach to resolving this challenge includesvering one area with a larger number of radio base stations, which would help address issues such as the need to miniaturize , energyvings, andst reductions. To address these challenges, from June 2020 to June 2023, Fujitsu Limited worked to develop technologies that enhance the performance of RU under a project initiated by NEDO, which can beed in information andmunications systems that support 5G. Fujitsu's research resulted in the development of a technology that enables multiple beam multiplexing on a single chip through millimeter-wave beamforming (4), making it possible to deliver four times the speed and larger capacity than anventional RU of theme size to deliver significant energy andst reductions.
Future Plans
Kicking off development of base station hardware equipped with this technology from Aut 2023, Fujitsu aims to beginmercial deployment of ing the technology globally in fiscal 2024, andntribute to the spread of millimeter-wave in the global market and decarbonization of the telmunications intry. Subsequently, the beam multiplexing technology will be applied to base station (CU/DU) products, and will be offered globally in fiscal 2025. In addition tontributing to the reduction of the carbon footprint of telmunications carriers and othermercialers, Fujitsu willntinue to develop technologies to advance thework intry andntribute to the rapid deployment of next-generationmunications infrastructure.
