TOKYO, Jan 30, 2023 - (JCN Newswire via SEAPRWire.com) - Yokohama National University, NTT DOCOMO, INC., NIHON DENGYO KOSAKU Co., Ltd. and Fujitsu Ltd. announced today that they successfully demonstrated a 5G indoor base station incorporating a multisector antenna using the 28GHz band on January 27. The device, which incorporates circuitry just 1/10th the size of a conventional indoor base station, is extra small for easy installation, minimizes energy consumption and achieves highly efficient signal propagation, all of which will contribute to the realization of high-quality connectivity indoors.The demonstration, in which a conventional 5G base station control unit communicated with the new device via a 28GHz signal, confirmed that a single multisector antenna can receive radio waves in all directions using radio beam control. DOCOMO previously measured the directivity of a single element in a multisector antenna in 2022, but the DOCOMO believes that this was the world's first demonstration to use a multisector antenna in a 5G base station equipped for radio beam control.A multisector antenna divides its surrounding 360-degree space into multiple areas (sectors) for transmitting ...
