Fujikura demos vehicle-to-infrastructure over 60 GHz millimeter-wave

Fujikura has demonstrated high-speed vehicle-to-infrastructure communication using an electric pole and in-house developed 60 GHz millimeter-wave wireless communication modules.

The demonstration, which was conducted in March in Himeji City, Hyogo Prefecture, confirmed the effectiveness of the safe driving support system for local bus services by vehicle-to-infrastructure communication.

In this demonstration, Fujikura installed a communication device equipped with the module on both electric poles and a local bus to establish a wideband wireless connection between the two. The module has successfully uploaded in-vehicle camera images in real time and also  transmitted the GNSS (global navigation satellite system) correction data necessary for high-precision vehicle positioning.

In addition, the module achieved a speed >2Gbps over a distance of >500m.

Other participants in the test included Kansai Transmission and Distribution, KYOCERA, Shinki bus Co., Panasonic System Networks R&D Lab, and Magellan Systems Japan.

Fujikura intros a Phased Array Antenna Module for 5G mmWave

Fujikura introduced a Phased Array Antenna Module (PAAM) for 5G mmWave operating in 3GPP bands n257 (28 GHz), n258 (26 GHz) and n261 (27 GHz). 

The Fujikura PAAM is a high performance phased array antenna module with a novel integrated antenna, and supports concurrent dual polarized beams in both transmission and reception. 

Fujikura is using mmWave-ICs developed in-house using a SiGe BiCMOS process. 

The PAAM features extremely low noise figure (NF) characteristics and enables a large link margin for expanded coverage. Tunable true-time-delay-type phase shifters support precise and independent phase and amplitude control over a wide frequency range. The unique phase shifter not only enables simple beam-steering control which allows accurate beam steering with fine resolution, but also allows calibration-free operation making PAAM installation much easier. The phase shifter also maintains the transmitted or received signals undistorted by providing invariant group delay and unchanged beam direction in a wide frequency range. In addition, Fujikura PAAM provides superior digital reconfigurability allowing (1) flexible choices in the trade-off space between NF and linearity --- this enables a wide range of coverage applications simply through digital reconfiguration of the PAAM, and on-chip support for 1000s of beam configurations. These are exactly the features highly desired by 5G wireless equipment manufacturers.

Sampling is expected by the end of 1Q 2021 with volume production in 2H 2021.

Fujikura develops 5G millimeter-wave module for 66~71GHz

Fujikura has developed a millimeter-wave communication module operating at a new 5G band (66~71GHz). The company has acquired a license for this frequency band to conduct a variety of experimental field tests, including for fixed wireless access and V2X applications.

The 66~71GHz range has already been allocated as an unlicensed band in the US, but WRC-19 has newly identified it as a globally allocatable 5G band and is expected to be used all over the world.
