MaîtreAnchor TDoA

Stationary Indoor UWB Network Gateway / Base Station for TDoA & TWR Positioning (Model FM-MA-TDOA)

FM-MA-TDOA UWB Ch 5 & Ch 9 Rx-Only / TDoA+TWR 86 × 46 × 38 mm • 68 g • ABS

Overview & Principle of Operation

MaîtreAnchor TDoA is a stationary indoor network gateway (base station) designed for industrial RTLS and smart building positioning systems. The anchor receives ultra-wideband blink packets from MaîtreBadge and MaîtreTag devices, performs hardware time-of-arrival timestamping (Time Difference of Arrival — TDoA, as well as Two-Way Ranging — TWR), and forwards aggregated telemetry to the positioning server over 2.4 GHz Wi-Fi or Ethernet.

  • Receive-Only (Rx-Only) & TDoA+TWR Modes: Can operate strictly as a passive UWB receiver (zero UWB RF emission) or in wireless clock-synchronized TDoA+TWR mode.
  • On-Site Diagnostics: Built-in OLED display shows network and server status, so installers can commission the anchor without a laptop.
  • Flexible Power & Backhaul: 5 V USB Type-C power or optional PoE over Ethernet.
  • Quick Installation: Side mounting flange for screw installation on walls, pillars, or overhead trusses.

Device Mounting & Deployment Guidelines

1. Mounting Height & Line-of-Sight (LoS)

  • Install anchors at a height of 2.5 to 5.5 m above floor level to maintain clear Line-of-Sight (LoS) to worn badges and asset tags.
  • For over-the-air clock synchronization, keep the reference anchor of each cell in direct LoS of the other anchors, at a spacing of 10–35 m.

2. Cell Geometry (GDOP)

  • Arrange anchors around the perimeter of the tracked zone with a cell aspect ratio no greater than 3:1 (square or near-square cells minimize Geometric Dilution of Precision).
  • Avoid collinear anchor placement when 2D/3D TDoA localization is required.

3. Clearance & Mechanical Fastening

  • Fasten the unit using the two Ø4 mm holes on the side mounting flange.
  • Maintain at least 15–25 cm clearance from large metal girders or sheet-metal ducts to prevent near-field multipath distortion.
