Tohoku University Technology: Relay-by-Smartphone (R): T13-121_S18-012

Tohoku University Technology: Relay-by-Smartphone (R): T13-121_S18-012

Smart data relay by DTN based LAN

　The invention is possible to create network among mobile devices autonomously and send/receive messages. Typically, it is too difficult to create network among mobile devices and negotiation/keep stable communication link. 　However, this invention is possible to negotiation/keep stable link and execute multihop communication by combination Delay Tolerant Network(DTN) like Mobile Ad-hoc Network(MANET) and wireless LAN. In inventor’s research, it was successful to communicate among smartphones directly and execute multihop communication. The communication method of this invention is possible to use other wireless communication instead of wireless LAN.

Hokkaido Univ. Technology：The most Advanced Analog RoF technology of Beyond 5G (6G)：HK24-009

Hokkaido Univ. Technology：The most Advanced Analog RoF technology of Beyond 5G (6G)：HK24-009

High-precision control of radio signals with simple configuration

　In order to increase the transmission capacity in wireless communication, the use of high frequency bands is being promoted, and it is required to reduce the load of signal processing in the base station. Specifically, the transition from digital optical wireless technology to analog radio-over-fiber (RoF) technology is being studied. However, in A-RoF, it is difficult to control the phase of radio waves in the base station, so MIMO (Multiple Input Multiple Output) signal processing also needs to be performed in the aggregation station. However, in the conventional A-RoF communication system, there is a problem that it is necessary to accurately control the phase of the A-RoF signal for each antenna element.　 　According to the present invention, it has become possible to provide a MIMO signal processing device and an optical wireless communication system that enable MIMO signal processing for beamforming that accurately controls the phase of the A-RoF signal that enable MIMO signal processing for multi-beamforming that accurately controls the phase of the A-RoF signal with monochromatic optical carrier wave.

Data communication within/between buildings via PLC communication.

Data communication within/between buildings via PLC communication.

The power lines between buildings are 6600V! Stable communication is achieved through a 200V PLC.

Communication within the building can be mixed using Ethernet and RS485 via PLC. The power lines between buildings are at 6600V, and due to regulatory restrictions, PLC communication is not possible. Therefore, we connect Wi-Fi to the PLC for communication. The distance between the 1st and 9th floors of Building 1 is approximately 20 meters. The PLCs on the 1st and 9th floors of Building 1 are out of phase, but stable communication is achieved by routing through a 200V PLC. 【Advantages of HD PLC Standards】 ■ Stable communication possible with wired connections ■ No need for new communication wiring work ■ High communication speed ■ One-touch setup allows easy installation even for light users ■ Capable of supplying higher current and voltage than Ethernet PoE *For more details, please refer to the PDF document or feel free to contact us.

Example of PLC Communication Utilization: "Network System for Buildings and Facilities"

Example of PLC Communication Utilization: "Network System for Buildings and Facilities"

Achieving a wide area network! Here are examples of utilizing HD-PLC, which enables high-speed communication with high reliability.

We would like to introduce examples of utilizing PLC communication in network systems for buildings and facilities that we propose. By combining power lines/dedicated lines and wireless communication within existing buildings, we can achieve a wide area network. This significantly reduces the installation costs for communication wiring for lighting and air conditioning control systems, various sensor monitoring, and surveillance cameras, thereby promoting the introduction of systems into existing buildings. Additionally, there are two types of PLC communication standards: "low-speed PLC," which superimposes low-frequency signals (up to 450 KHz), and "high-speed PLC," which superimposes high-frequency signals (2 to 28 MHz). "HD-PLC," classified as high-speed PLC, contributes to our customers' IoT, EMS, and Automation services due to its characteristics. *For more details, please refer to the PDF materials or feel free to contact us.
