DOCOMO tests 28 GHz-band 5G aboard Shinkansen

NTT DOCOMO achieved the first 28 GHz-band 5G mobile communications between base stations and a high-speed bullet train during experimental trials with Central Japan Railway Company (JR Central).

The test was conducted between a 5G experimental mobile terminal, installed in a test version of an N700S-model Shinkansen railcar traveling at 283 km/h, and 5G experimental base stations erected temporarily along the Tokaido Shinkansen tracks. DOCOMO reports  speeds exceeding 1.0 Gbps and consecutive handover among three base stations located along the tracks. The transmissions were facilitated with advanced beamforming and beam tracking technologies incorporated in the 5G experimental mobile and base stations. Also, ultra-high-definition 8K video contents were rapidly downloaded from the base stations for delivery to the railcar's mobile terminal and 4K video of the passing scenery was relayed live from the railcar's mobile terminal to the base stations.

Fujitsu delivers 5G base station products to NTT DOCOMO

Fujitsu Limited has begun delivery of 5G base station products, comprising of Central Unit (CU, 1) and Radio Unit (RU, 2), to NTT DOCOMO for its commercial 5G network.

The 5G CU products that Fujitsu has started delivering realize the 5G system through a proprietary software design from the company using software-defined radio technology, which can implement different wireless technologies on the same hardware.

The 5G RU products have built-in antennas (which had conventionally been installed externally) equipped with beam forming, enabling efficient network deployments. These RU products have a lineup consisting of 3 types of equipment that support 5G frequencies (the 3.7 GHz band, the 4.5 GHz band, and the 28 GHz band). he products are compliant with the O-RAN fronthaul interface specifications. Using this open interface, Fujitsu's products can connect to various vendors CU/RU products. The products also support 3GPP's (Release 15) specifications.

Fujitsu said it has been working with NTT DOCOMO to develop a CU and RUs that comply with the O-RAN fronthaul interface specifications. T

Hiroshi Nakamura, Executive Vice President and Member of the Board of Directors, NTT DOCOMO, states "NTT DOCOMO is leading the O-RAN Alliance and contributing to the creation of specifications for open RAN. By utilizing 5G base station products compliant with open interfaces, we will build a flexible and efficient 5G network that can handle a variety of use cases, including the B2B2X business in the 5G era. We expect that Fujitsu's CU and RU products will contribute to such development. We will continue to expand our 5G network and accelerate the creation of 5G services and markets together with our partners in a variety of industries."

Tokyo Tech's 28 GHz transceiver with dual-polarized MIMO hits 15 Gbps

Researchers at Tokyo Institute of Technology have developed a 28 GHz transceiver that integrates beamforming with dual-polarized multiple-input and multiple-output (MIMO) technology.

Preliminary testing showed that the maximum data rate achieved was 15 Gbps using 64-QAM.

The transceiver measures just 3 mm by 4 mm and could help improve performances of 5G and Internet of Things (IoT) devices.

"Compared with the conventional switch-based bi-directional approach, our bi-directional amplifier completely shares the inter-stage matching networks between the transceiver and the receiver. Thus, the required on-chip area is further minimized," states Kenichi Okada at Tokyo Tech's Department of Electrical and Electronic Engineering.

Tokyo Tech develops atomic clock for small satellites

Researchers at Tokyo Institute of Technology, Ricoh co. and Japan's National Institute of Advanced Industrial Science and Technology have developed an ultra-low-power atomic clock (ULPAC) for small satellites.

The fully functional atomic clock consumes an order of magnitude less power than that of previously reported devices. It also excels in two other critical aspects: volume occupied and Allan deviation, which is a measure of the stability of the frequency of a clock.
