• Product Overview

    The A101 is a high-precision Real-Time Locating System (RTLS) anchor utilizing Ultra-Wideband (UWB) wireless communication technology. Featuring a sleek ceiling-mount industrial design, it is optimized for high-precision indoor positioning across various sectors. The system supports the TDOA architecture, delivering a typical positioning accuracy of 10–30 cm.

    The A101 offers exceptional architectural flexibility, functioning as either a synchronization transmitter for Downlink TDOA or a receiving terminal for Uplink TDOA. In Downlink mode, the A101 supports autonomous offline operation, significantly reducing dependency on network infrastructure.

    Key Features

    1. Dual-Mode Support: Compatible with both Uplink and Downlink TDOA architectures to meet diverse business requirements.

    2. Precision Clock Synchronization: Utilizes proprietary synchronization technology to maintain a time error between anchors of less than 0.6 ns, ensuring centimeter-level stability.

    3. Flexible Networking: Equipped with built-in Wi-Fi; supports autonomous offline operation when configured as a Downlink TDOA anchor.

    4. Simplified Deployment: Features a standard USB Type-C 5V power interface, compatible with common 5V/1A power adapters to simplify onsite wiring.

    5. Smart Management: Supports USB HID for initial local configuration and network-based remote parameter tuning.

    6. IP Management: Supports both DHCP for automatic IP allocation and static IP assignment.

    7. Auto-Discovery: Capable of automatic discovery by the positioning engine.

    8. Standards Compliance: Each device features a unique EUI-64 ID; supports PAN ID filtering to exclude irrelevant UWB packets; fully compliant with IEEE 802.15.4-2011 standards.

    9. Advanced RF Tuning: Configurable UWB parameters including preamble length, PRF, and PAC to adapt to complex multi-path environments.

    10. Maintenance & Monitoring: Supports Over-the-Air (OTA) firmware updates; features an integrated status LED with adjustable brightness.

UWB Module SDWM1000 Circuit Diagram and PCB - Price: $300 USD

This is our later mass production module. The module uses a PCB antenna and uses pin headers to connect to the anchor chassis. Can be directly adapted to two models of indoor anchors, A1102P and A1106P.

This module has basically the same circuit as the original DWM1000 and has no extra functions. Please note that LNA and PA are not added .

We have tested that when using 850K rate, the longest communication distance is about 200 meters to 300 meters .

Someone may wonder why the module circuit is more expensive than the anchor backboard circuit? 

Because of the difficulty! Hardware engineers know that in most cases, digital circuits are simpler than analog circuits.

Although we have modified the chassis of the single network port anchor dozens of times, the changes are all in details. It cannot be said to be worthless, but it is not strictly necessary.

In the early days, in order to reduce the difficulty of research and development, we always used the original UWB module. As the product matured and we hoped to reduce production costs, we decided to develop our own UWB module. The difficulty in developing UWB modules mainly lies in wiring. The wiring of the RF circuit is not just about impedance matching. This has always been a technical job, which requires not only theoretical support but also empirical support. We tried it many times before we got a satisfactory result. You can think about it, how long does it take a qualified engineer who is proficient in RF wiring to figure this thing out? How much salary are you going to pay him? For this price, it's just free of charge.
