DWM1000 概要
An ultra-wideband transceiver module is a self-contained RF subsystem that combines the radio IC, antenna, RF matching, power management, and clock circuitry into one package, eliminating the RF design work normally required for a discrete UWB chip. In the product hierarchy, the DWM1000 sits between the DW1000 transceiver IC (the silicon) and complete positioning systems such as two-way ranging (TWR) or TDOA location networks.
Key features include a 500 MHz-wide UWB channel implementation compliant with IEEE 802.15.4-2011, data rates of 110 kbps, 850 kbps, and 6.8 Mbps, and an integrated chip antenna. Supply voltage is 2.8 V to 3.6 V with typical receive current of 64 mA. Because the antenna and all RF components are on-module, no RF layout expertise is needed - the DWM1000 connects to a host MCU over a standard SPI interface.
Technically, the module is built around the DW1000 single-chip CMOS UWB transceiver, which supports timestamps with sufficient resolution for centimeter-level ranging. The onboard DW1000 temperature sensor can dynamically trim the crystal during runtime to hold the +/- 2 ppm frequency specification across the full -40C to +85C operating range, according to Qorvo documentation.
Typical applications include indoor asset tracking with 10 cm precision, TDOA and TWR positioning anchors and tags, factory automation, warehouse logistics, smart-building occupancy sensing, and RTLS research using platforms such as Arduino or ESP32 hosts.
A key design consideration is power: receive current of 64 mA dominates duty-cycled tag designs, so sleeping the DW1000 between frames and using the lowest data rate with preamble optimization for range, or the highest rate for battery life, is an important trade-off to model early.

主な用途
DWM1000 の用途: 6 件s: Indoor Asset Tracking (RTLS), TDOA Location Infrastructure, Warehouse and Logistics Automation, Smart Building Occupancy and Access, Robotics and Drone Relative Navigation, Prototyping and RTLS Research.
Indoor Asset Tracking (RTLS)
The DWM1000's 10 cm two-way ranging precision makes it a foundational component for real-time location systems tracking tools, pallets, returnable containers, and medical equipment inside factories and hospitals. Because UWB pulses at 500 MHz bandwidth resolve multipath far better than BLE or Wi-Fi RSSI approaches, the module delivers consistent accuracy where 2.4 GHz systems degrade. In a typical deployment, tags built around the DWM1000 periodically range against fixed anchors, and the 64 mA receive current is managed through sleep modes between burst windows to extend battery life. The integrated chip antenna means each tag is a simple two-layer PCB: module, MCU, power supply, and battery. According to Qorvo, both TWR and TDOA architectures are supported, letting designers trade tag complexity against anchor infrastructure density.

TDOA Location Infrastructure
In time-difference-of-arrival systems, the DWM1000 acts as the radio front end in ceiling- or wall-mounted anchor nodes that timestamp incoming UWB bursts and forward data to a location engine. The module's +/- 2 ppm crystal accuracy - maintained by runtime temperature trimming using the DW1000's onboard sensor - directly determines timestamp consistency across anchors, which is the dominant error source in TDOA. Because the module integrates antenna, RF, clock, and power management, an anchor node reduces to the DWM1000, a host MCU or gateway processor, Ethernet/LoRa backhaul, and power regulation. Anchors typically operate from mains power, so the 64 mA receive current is less critical than in tags, and the 6.8 Mbps data rate allows high tag-density networks with short airtime per event.
おすすめ
Warehouse and Logistics Automation
Warehouse operators use DWM1000-based tags to track forklifts, AGVs, and high-value inventory through TDOA corridors or TWR zones, achieving the 10 cm precision needed for lane-level and rack-level localization. The module's 6.8 Mbps rate supports frequent position updates (the community commonly targets 100 ms update cycles), and the -40C to +85C operating range suits unconditioned dock and cold-storage environments. Integration is straightforward: the module speaks SPI to any industrial MCU, and its castellated edges allow reflow or hand assembly. Compared with UHF RFID, UWB ranging adds direction and continuous trajectory data rather than gate events, enabling collision avoidance between vehicles and workers - a safety application where centimeter-grade, low-latency positioning directly reduces incident risk.
おすすめ
Smart Building Occupancy and Access
UWB's secure, precise physical-layer characteristics make the DWM1000 suitable for presence detection, hands-free access control, and room-level occupancy analytics in commercial buildings. Unlike passive-IR or camera systems, UWB ranging resists spoofing and preserves privacy by measuring only time-of-flight. The integrated chip antenna and castellated SMD package let designers embed the module inside light fixtures, access readers, and wall sensors without RF expertise. A 2.8 V to 3.6 V supply suits direct operation from a single lithium cell or a 3.3 V rail, and sleep-mode operation keeps sensor-node average current low between polling windows. Combined with an MCU running a simple TWR exchange against a door- or room-side anchor, the module distinguishes approach, entry, and presence states with sub-10 cm confidence.
おすすめ
Robotics and Drone Relative Navigation
Autonomous mobile robots and drones operating indoors lack GPS, and the DWM1000 supplies the missing absolute-position reference: pairs of modules exchange two-way-ranging frames to compute relative distance with 10 cm precision, and a fixed anchor set provides full pose estimation. The 6.8 Mbps rate keeps ranging latency low enough for control loops, and Qorvo forum threads document working integrations with Arduino/Teensy and ESP32 hosts. Because the module integrates all RF and clock circuitry, integrating UWB onto a robot baseboard is a digital design task - SPI routing and 3.3 V power only. Designers should account for the 64 mA receive current in the vehicle's power budget and mount the module's chip antenna clear of carbon-fiber frames and metal structures to preserve the radiation pattern.
おすすめ
Prototyping and RTLS Research
The DWM1000 is the standard teaching and research module for ultra-wideband localization: universities and maker communities build TWR experiments with ESP32, Arduino, and Teensy hosts, aided by Qorvo's DWS1000 Arduino-compatible shield and extensive community code. The module's SPI interface needs only four signals plus reset and wake, so a breadboard-adjacent prototype is achievable in an afternoon, and datasheet-documented registers expose channel, preamble, data-rate, and antenna-delay tuning for research into NLOS mitigation, sensor fusion, and security. The mature deployed base and active Qorvo Tech Forum shorten debugging dramatically compared with newer silicon. For research budgets, the lower-cost BU01 module (same DW1000 die) offers per-node savings when ordering tens of modules for anchor arrays.

設計ノート
Although the DWM1000 needs no RF design, the host PCB still matters: keep the module's chip antenna edge overhanging or free of ground pour per the Qorvo datasheet keep-out zone, and avoid placing metal enclosures, batteries, or carbon-fiber structures within the antenna near field. Use castellated edges for reflow assembly or add test pads on the SPI bus (SPICLK, MISO, MOSI, NSS) for bring-up debugging. Estimate: allocate at least 5 mm clearance around the antenna side of the module.
Design the 2.8 V to 3.6 V supply for the 64 mA receive current plus transmit bursts, not the average sleep current - a supply that sags during TX windows corrupts timestamps. Place a low-ESR bulk capacitor (estimated 10 uF) near the module supply pins plus 100 nF decoupling. For battery tags, budget the DW1000 sleep/deep-sleep modes and wake-up time when calculating average current; the lowest data rate (110 kbps) maximizes link budget while the 6.8 Mbps rate minimizes airtime and thus energy per packet.
Calibrate antenna delay per unit - the single most common source of ranging bias in DWM1000 systems. Also confirm you are buying the V2 hardware (post-July 2020, per PCN019), since V1 is no longer produced and mixed V1/V2 fleets can show small performance deltas. For interoperability plans, remember that the DWM3000 requires firmware migration per Qorvo's forum guidance, and cross-vendor modules (BU01) must be validated for footprint and antenna placement on your specific PCB before qualification.
