Ultra-wideband (UWB) is a short-range, wireless communication protocol that operates through radio waves, enables secure reliable ranging and precision sensing, creating a new dimension of spatial context for wireless devices. It is widely in indoor position/ tracking.
This DSTO(Distributed Synchronization and Two-way Observation) chipset is based on UWB tech for distributed ranging system, that all the nodes (Max 20 with default firmware)in the system reports distance between itself with each other nodes, Compares to MaUWB_DW3000, the main difference:
| Comparison | MaUWB_DW3000 | MaUWB_DSTO |
| Ranging Logic | Tags can only measure the distance to a fixed base station (anchor). Tags cannot communicate with each other. | Within the effective communication range (approx. 200m open/visible), every device can acquire the distance of all other devices in real-time. |
| Usage | Positioning | Safety/Anti-collision |
| Refresh Rate | Max 100Hz | Max 500Hz |
| Deployment Difficulty | High: Requires setting up anchors in advance, calibrating coordinates, Math calculation for positioning | Low: No central node required. Devices automatically form a network when powered on; plug-and-play. |
| System Capacity | 8 Anchors(automatic select the newest 8 anchors) + 64 Tags | Theoretically unlimited IDs (Note: By default 20 devices in the same area/100m radius to avoid data loss in default firmware) |
With this mode, users can get from every nodes in the system, of the distance between itself to every other nodes, to create distance real time(max 500 hz) monitoring sytesm, thus to avoid collision. Of course, if few of the nodes fixed, it can be also used for positioning of the mobile one, as it get distance between the fixed nodes.
What is it used for?
It is used for "High-frequency interaction" and "Safety/Anti-collision":
