Product brief

The MK UWB Kit RTLS is the ideal entry point to learn how to implement an indoor Real Time Location System (RTLS) using Time Difference of Arrival (TDoA) multilateration technique.

TDoA can be used to determine a device position by measuring the time it takes for a UWB signal to be received at several fixed anchor devices placed in the monitored environment. Thanks to TDoA multilateration, UWB can be used to reliably compute the location of assets and people in indoor environments:

  • Accurate: compared to other technologies, UWB allows you to obtain very accurate positioning measurements with a precision down to centimeters, even in indoor environments.
  • Real-time: TDoA positioning data can be processed in real-time by the backend RTLS engine. You can know at each instant where tracked devices are and trigger actions based on their position or movement pattern.
  • Scalable & Power efficient: The broadcasting nature of TDoA-based positioning makes it power-efficient and easily scalable to track tens of devices simultaneously using an infrastructure of anchors.

Experience firsthand the numerous advantages of UWB for real-time positioning and use the tools and examples included in the kit to kick-start the development of your own RTLS solution based on NXP’s TrimensionTM UWB ICs.

With the MK UWB Kit RTLS:

  • Experience how to track one or more UWB-enabled tags using fixed anchor devices leveraging on TDoA-based real-time positioning. The MK UWB RTLS demo software allows you to experience first-hand the capabilities of the technology.
  • Kick-start the design of your own UWB RTLS solutions by leveraging on the hardware and software examples provided with the kit.

Hardware materials

MK UWB Anchor RTLS

Flexible platform to develop customized UWB systems featuring NXP's UWB chipset TrimensionTM SR150, as the backbone infrastructure of the RTLS system to track UWB tag devices.

The customized ABS casing is ideal for tripod or wall mounting and can be easily opened to access the anchor debug interfaces. Velcro strips on the side of the anchor allow for easy mounting of external power banks (Not included in the kit).

UWB Tag SR040

Autonomous, battery-powered UWB device that features NXP's UWB chipset TrimensionTM SR040 and a BLE-enabled microcontroller, enabling all kinds of tracking and localization use cases, including UWB RTLS tracking using uplink TDoA multilateration.

The tags act as tracked devices in the RTLS infrastructure. The ABS casing makes it easier to carry the tag around and can be easily opened to access the tag debug interfaces.

Besides the hardware components described, the MK UWB Kit RTLS also comes with a USB drive containing software and documentation resources.

Software materials

The MK UWB RTLS Demo Android application showcases how UWB technology can be used to implement an uplink TDoA-based RTLS solution:

  • The MK UWB RTLS Demo uses Bluetooth LE to communicate with the anchors and is responsible for the system configuration, collecting the TDoA data from the anchors and executing the multilateration algorithm to compute the real time location of the tracked device.
  • Track up to 4 UWB-enabled tags using an infrastructure of 4 fixed anchors
  • Several configurations and personalization options
  • Step-by-step documentation and quick installation guide to position the hardware and run the demo
  • Source code of firmware applications and Android application so you can kick-start the design of your own RTLS solution

Documentation

The documentation provides step-by-step instructions to install anchors, run the UWB RTLS Demo and experience real-time, TDoA-based positioning. You can also find tips and guidelines to start developing your own RTLS use cases.
