Bluetooth AoA Anchors for
Sub-Meter Indoor Positioning
Blueiot's Bluetooth Angle of Arrival anchors deliver 0.3m accuracy and up to a 45m positioning diameter per anchor-the new standard for Bluetooth indoor tracking and RTLS.
Two Bluetooth AoA Locators,
One Indoor Positioning Engine
The Standard and Enhanced anchors share the same Blueiot Bluetooth AoA engine and 0.3m accuracy, so you can mix and match them across indoor and outdoor zones-from indoor asset tracking to large-area RTLS-in a single platform.
A slim, lightweight indoor positioning anchor built for offices, hospitals, and retail indoor tracking.
An industrial-grade RTLS anchor engineered for large-scale indoor positioning and outdoor asset tracking.
The Most Accurate Bluetooth
Indoor Positioning, Engineered
Across the Full Stack
Antenna hardware, on-device firmware, and the positioning engine are designed together to deliver a stable 0.3m solution—backed by 12 years of AoA R&D.

Hardware
A self-developed omnidirectional antenna array captures the signal's Angle of Arrival in every direction at once.
Dense phased-array element layout- Wide 2.400–2.4835GHz reception
- Coverage up to a 60m positioning diameter
Firmware
On-anchor firmware computes phase difference and suppresses multipath in real time, before data leaves the device.
- Real-time phase-difference computation
- Multipath & reflection suppression
- Intelligent environment adaptation
Software
The Blueiot AoA engine fuses every anchor's angle data into precise 3D coordinates for visualization and geofencing.
- Sub-meter coordinate solving
- 2D/3D visualization & geofencing
- Trajectory playback and analytics
From Angle of Arrival to Precise Coordinates
Multiple anchors work together to cover large, complex spaces. Triangulation and data fusion improve accuracy and stability across the entire deployment.
Measure the angle
The anchor's antenna array measures the pitch and heading angle of each incoming Bluetooth signal with phase-difference precision.
Single-anchor 2D fix
Using the known height difference between tag and anchor, a single anchor computes 2D (X, Y) coordinates in real time.
Multi-anchor 3D fusion
Intersecting angles from multiple anchors are triangulated to calculate full 3D (X, Y, Z) coordinates of the tag.
Anchor + Tags + Software = Full RTLS
Blueiot anchors are one part of a complete real-time location system. Pair them with our tags and positioning engine to unlock full-stack indoor tracking and geofencing.
