How Qorvo’s DWM3001CDK Enables Precise RTLS
Qorvo’s DWM3001CDK is an ultra-wideband (UWB) module development kit that enables developers to build an evaluation real time location system (RTLS) as a Two-Way Ranging (TWR) or Time Difference of Arrival (TDoA) tag. The DWM3001CDK allows users to evaluate DWM3001C 6.5 & 8.0 GHz UWB module with integrated Bluetooth low energy (BLE) system-on-chip (SoC) and Motion Sensor. Based on Qorvo DW3110 IC wireless transceiver, the DWM3001CDK utilizes the power of UWB technology to deliver location precisions within 10 cm accuracy, robust battery reliability, and immunity to multipath and interference.

The DWM3001CDK is equipped with two micro USB ports that connect to the J-Link and DWM3001C interface (Figure 1). Designed to be FiRa™ PHY and Mac compliant, the DWM3001CDK supports UWB RF bands 5, 9, and its software suite is also fully compliant with FiRa/PHY/Mac specifications. The DWM3001CDK can be powered through USB ports, a Raspberry Pi interface, battery, or other external power supply.
Additionally, the DWM3001CDK is interoperable with Apple’s Nearby Interaction Beta Evaluation Software. With a U1-equipped iPhone of Apple Watch, developers are able to evaluate new app features based on location, distance, and direction through the DWM3001CDK.
