UWB RTLS Positioning Module Decawave DW1000 – RAKwireless RAK13801

The RAKwireless RAK13801 is a WisBlock IO UWB module built around the Decawave DW1000, intended for high-precision real-time location systems (RTLS) and location-aware sensor networks. UWB (Ultra Wideband) is a short-range wireless technology (similar in deployment scenarios to Wi-Fi or Bluetooth) that uses a bandwidth above 1 GHz, making it well-suited for accurate ranging and positioning.

For product teams and system integrators, the RAK13801 reduces RF design effort by integrating key radio building blocks into a single module: an integrated antenna, RF circuitry, power management, and clock circuitry. It supports both two-way ranging and TDOA-based location systems, enabling asset positioning down to 10 cm precision as stated in the description, with data rates up to 6.8 Mbps.

Typical deployments include:

RTLS asset tracking in factories and warehouses (tools, pallets, vehicles, high-value items)

Automation workflows where location triggers events (process validation, zone entry/exit rules)

Security systems that depend on reliable tag presence and positioning

High-density RTLS environments, supported by the module’s stated ability to handle high tag densities and its strong multipath immunity

With low power consumption highlighted in the provided text, the module is also suitable for battery-powered tags where reducing maintenance and lifetime cost is a key buying driver.
