Fujitsu Research and Development Center Co., Ltd. Key Developments

Fujitsu Laboratories Ltd. and Fujitsu R&D Center Co., Ltd. Develop Platform to Easily Manage Diverse Range of IoT Devices

Fujitsu Laboratories Ltd. and Fujitsu R&D Center Co., Ltd. announced the development of a software platform that enables the centralized and stable management of operating status for a variety of sensors, devices, and gateways, as well as the condition of the network that connects them. This platform will support the operation and management of an anticipated and growing array of IoT services. In developing this new platform, Fujitsu Laboratories and Fujitsu R&D Center have defined common Application Programming Interface (API) to enable consolidated management of IoT device and network status, as well as the monitoring information required to analyze the cause of faults. They have also realized functionality, based on a plug-in format, so as to harmonize differences between common-API and IoT-device interfaces. In this way, it becomes a simple matter to develop tools for remote monitoring and fault analysis in IoT devices and networks, while enhancing both freedom in device selection and flexibility when systems are scaled up, greatly contributing to stable operations. Fujitsu Laboratories and Fujitsu R&D Center have now developed a software platform that centrally manages operations information from devices, including IoT devices and gateways and the connecting network devices that make up the system to enable fault analysis. Plug-in-based adapter to handle different protocols - Fault analysis API. Furthermore, regarding information-collecting APIs, Fujitsu Laboratories and Fujitsu R&D Center are promoting the standardization of the API related to wireless fault monitoring under IEEE802.1CF.

Fujitsu R&D Center Co., Ltd. and Fujitsu Laboratories Ltd. Announce the Development of New Wireless Technology

Fujitsu R&D Center Co., Ltd. and Fujitsu Laboratories Ltd. have announced the development of a new wireless technology that reportedly doubles the capacity of a single cell, using the same wireless frequency simultaneously, as a step toward 5G. Full-duplex is a technology that simultaneously transmits and receives wireless signals on the same frequency, which is a way to increase wireless communication capacity, but reducing interference from the sending signal to the receiving signal is problematic. Fujitsu has developed a new scheduling technology that reduces the inter-device and inter-base-station interference, using a transceiver separation type where separate base stations are responsible for the tasks of sending and receiving to multiple devices within the same cell. This results in a communication capacity of up to double the current existing half-duplex communication technology within a single small cell. In wireless environments with a high concentration of users, such as shopping malls or stadiums, it is anticipated that this will result in a smoother communication environment that reduces capacity loss. Targeting the commercial launch around 2020, 5G, the next-generation wireless communication system, is currently being researched and developed to fulfil the explosion in communication volumes caused by the popularity of smartphones, and to support the expected future proliferation of services. It is estimated that wireless communication capacity will need to be 1,000 times greater in 2020 than in 2010. To satisfy this, the 5G system uses small cell technology for which research and development are already under way. In small cell technology, the area covered by a given base station is narrower and a given frequency is used in different areas. Only using small cell technology by itself to continuously deal with increasing communication capacity is problematic. Full-duplex - a technology where wireless signals are simultaneously sent and received on the same frequency - is used to increase capacity. Fujitsu has developed a transceiver separation type full-duplex communication technology that reduces inter-base-station and inter-device interference by using a base-station transceiver separation architecture. Fujitsu also developed a scheduling technology to enable this approach to full-duplex. Types of processing include optimized device pairing and optimized device transmission power control. Optimized device pairing selects the two devices within a single small cell that have the least mutual interference when using the same frequency. Optimized device transmission power control Controls transmission power so as to ensure wireless quality and minimize interference with other devices using the same frequency at the same time. Optimized scheduling for a device takes into account combinations of three factors: the device receiving the downlink signal, the device sending the uplink signal, and the device's transmission power. Assuming there are ten candidates for each factor, signal processing here needs to check a total of some 1,000 combinations. Fujitsu developed an algorithm that puts the candidates into the best ordering, which reduces the signal-processing workload for device scheduling to a few tenths of what it would be otherwise for these three types of candidates. They also developed an algorithm that accurately picks transmission-power candidates based on the grouping of devices, which reduces the processing workload to about 1/40th overall. In system-level simulations using this technology, a single small cell was found to achieve up to twice the communication capacity of existing half-duplex communication. In wireless environments with a high concentration of users, such as shopping malls or stadiums, installing this technology will provide smoother communication environments that limit capacity degradation.
