Fujitsu Component Limited’s beacon family employs Nordic’s nRF51822 SoC to provide wireless connectivity, sensor management, and over-the-air updating
Nordic’s nRF51822 is a powerful and flexible multiprotocol SoC ideally suited for Bluetooth LE and 2.4GHz ultra low-power wireless applications. The nRF51822 is built around a 32-bit ARM® Cortex™ M0 CPU, 2.4GHz multiprotocol radio, and 256kB/128kB Flash and 32kB/16kB RAM. The SoC is supplied with Nordic’s S130 SoftDevice, a Bluetooth 4.2 qualified concurrent multi-link protocol stack solution supporting simultaneous Central/Peripheral/Broadcaster/Observer role connections.
“The nRF51822 SoC controls the wireless connectivity, sensors, LED, and battery management in the beacons,” says Fujitsu Component Limited Director of Global Marketing, Takashi Arita. “We selected the Nordic SoC because of the ARM processor, great radio characteristics, low power consumption, easy control, and its overall flexibility.
“We enjoy close cooperation with Nordic teams worldwide and benefit from the technical assistance and information they provide.”
Shimane Fujitsu Limited is employing Fujitsu Component beacons to resolve issues with its pre-shipping repair process in its laptop PC and tablet manufacturing facility in Shimane, Japan. For real-time visualization of the process a beacon is attached to each product needing repair that is sent to the repair line, enabling all line workers to be aware of each product's location in the process, how long it has been there, and its shipping deadline. As a result, all employees can quickly understand the state of the entire process, allowing them to independently prioritize the repair of products that have close shipping deadlines, or to assist in processes that are causing delays. According to the company this has led to a reduction of extra transportation costs by 30 percent.
The company is also developing a new generation of beacons based on Nordic’s nRF52 Series SoCs with embedded sensors, energy harvesting solutions, and running the Wirepas scalable decentralized radio communications protocol for beacon management.
