Multibeam multiplexing innovation allows high-speed, high-capacity interactions over 10 Gbps and decreases power intake by 30%
TOKYO, Aug 28, 2023 – (JCN Newswire) – Fujitsu Limited revealed the advancement of a brand-new millimeter-wave chip for 5G that supports multibeam multiplexing (leaving out polarization multiplexing (1 )), allowing approximately 4 beams to be multiplexed by a single millimeter-wave chip for the radio systems (RU) of 5G base stations. The advancement was carried out as part of the “Research and Development Project of the Enhanced Infrastructures for Post-5G (2) Information and Communication Systems” (3) commissioned by Japan’s New Energy and Industrial Technology Development Organization (NEDO).

With traditional innovations, a single millimeter-wave chip is utilized to create a single beam, leading to bigger RUs and increased power intake. When the freshly established innovation is used to real base stations, Fujitsu showed that it is possible to accomplish high speed and high capability interactions of 10 Gbps or more with a half the size of a standard RU. This permits systems with less millimeter-wave chips, which eventually causes decreases in power intake per RU by 30%.
Project Background
5G network innovations are anticipated to accomplish greater speeds and capability by successfully making use of cordless resources in the millimeter-wave band. While this method provides the prospective to substantially enhance interactions speed and capability, millimeter and other high-frequency radio waves tend to be obstructed by challenges, making it tough to interact in between country miles. One possible method to solving this difficulty consists of covering one location with a bigger variety of radio base stations, which would assist deal with concerns such as the requirement to miniaturize RUs, energy cost savings, and expense decreases. To deal with these obstacles, from June 2020 to June 2023, Fujitsu Limited worked to establish innovations that boost the efficiency of RU under a task started by NEDO, which can be utilized in details and interactions systems that support 5G. Fujitsu’s research study led to the advancement of an innovation that allows numerous beam multiplexing on a single chip through millimeter-wave beamforming (4 ), making it possible to provide 4 times the speed and bigger capability than a standard RU of the exact same size to provide considerable energy and expense decreases.
Future Plans
Kicking off advancement of base station hardware geared up with this innovation from August 2023, Fujitsu intends to start industrial release of RUs utilizing the innovation worldwide in financial 2024, and add to the spread of millimeter-wave in the worldwide market and decarbonization of the telecom market. Consequently, the beam multiplexing innovation will be used to base station (CU/DU) items, and will be used worldwide in financial2025 In addition to adding to the decrease of the carbon footprint of telecoms providers and other industrial users, Fujitsu will continue to establish innovations to advance the network market and add to the fast release of next-generation interactions facilities.
