Antenna for 5G developed by NEC
A massive-element active antenna system (AAS) has been developed by NEC Corporation, which will be suitable for use with next-generation 5G wireless communication standards.
The AAS, which supports the 100 MHz bandwidth, adopts a fully digital control system that enables the forming of precise directional signals (beams) in multiple-input multiple-output (MIMO) systems for devices such as smartphones and tablets, through the use of 64 antenna elements.
These features enable high spectral efficiency, at more than 15 times the throughput of LTE per cell, even in environments where terminals are unevenly distributed and moving.
“Massive-element active antenna systems that utilise the low-SHF band are an important component in realising high-speed and high-capacity communications needed for 5G,” said Katsumi Tanoue, deputy general manager, Mobile Radio Access Network Division, NEC Corporation.
“Through verification trials using the newly developed AAS, we will evaluate the usefulness of technologies for increasing spectral efficiency and contribute to the commercialisation of 5G.”
In addition, NEC integrated the antenna and wireless processing components into one unit through the use of highly integrated circuits and highly dense printed circuit boards, in order to develop a practical system that is compact and lightweight.
NEC will exhibit the product and its other efforts in 5G systems at Mobile World Congress 2017 to be held in Barcelona, Spain, from 27 February to 2 March 2017.
