The A101 is a high-precision real-time positioning anchor based on UWB (ultra-wideband) wireless communication. It uses a ceiling-mount industrial design and is widely used in indoor high-accuracy positioning scenarios. The system supports a TDOA positioning architecture, with typical positioning accuracy of 10–30 cm.

The device is highly flexible: it can serve as a synchronized transmitter in downlink TDOA mode or as a receiving endpoint in uplink TDOA mode. In downlink mode, the A101 can run standalone without a network, which greatly reduces dependence on network infrastructure.

Key features

• Multi-mode support: Compatible with uplink and downlink TDOA positioning modes to suit different deployment models.
• High-precision clock sync: Proprietary clock synchronization keeps inter-anchor time error below 0.6 ns for stable centimeter-level positioning.
• Flexible networking: Built-in Wi-Fi; in downlink TDOA mode, operation without a network is supported.
• Power and deployment: Standard USB Type-C 5 V input, compatible with common 5 V / 1 A adapters for easier cabling.
• Smart management: USB HID for local configuration and remote parameter tuning over the network; DHCP or static IP.
• Security and compatibility: Unique EUI-64 ID, PAN ID filtering; conforms to IEEE 802.15.4-2011.
• RF tuning: Configurable preamble length, PRF, PAC, and other UWB parameters for challenging multipath environments.
• Maintainability: Over-the-air (OTA) firmware updates; multi-function status LED with adjustable brightness.
