Hayato Information Co., Ltd. (HQ: Shinjuku, Tokyo) has announced an update to its indoor positioning system, 'Docone,' which will refresh its receiver configuration—previously limited to proprietary units—to offer a new option utilizing commercially available generic communication modules.

By adopting affordable modules like the 'MDBT50Q,' which features Nordic Semiconductor’s nRF52840, the cost per receiver can be significantly reduced compared to traditional proprietary units.

Furthermore, by utilizing the MDBT50Q as a BLE mesh node, the system now supports mesh communication via BLE Long Range (LE Coded PHY). Under line-of-sight conditions, it can achieve a range of approximately 50 meters per hop, with up to 8-hop relays covering a theoretical distance of 400 meters. The service is scheduled to launch in June 2026.

Background 'Docone' has traditionally relied on proprietary receivers to ensure stable quality and support. However, high equipment costs in large-scale facilities have been a challenge. This update significantly lowers the cost barrier by allowing the use of inexpensive off-the-shelf modules.

Key New Features 1. Use of affordable generic modules: Offers a choice between traditional proprietary units and off-the-shelf modules. 2. Adoption of MDBT50Q mesh nodes: Uses the widely available and reliable nRF52840. 3. Mesh communication via BLE Long Range: Supports up to 8 hops, covering a theoretical range of ~400m. 4. Simplified internet connectivity: Only the master node requires an internet connection; slave nodes operate on power only.

Benefits Significant reduction in receiver costs, ease of large-scale deployment, flexible system selection, reduced cabling, wide-area coverage, scalable expansion, and improved redundancy.

Upgrades for Existing Users Upgrades will be provided to allow existing users to extend their system coverage and reduce costs without interrupting operations.
