Bluetooth AoA / AoD

Bluetooth direction finding for indoor location projects

Overview

What is Bluetooth AoA / AoD?

Bluetooth Angle of Arrival (AoA) and Angle of Departure (AoD) are direction-finding methods that use compatible Bluetooth hardware to estimate signal direction. With suitable tags, antenna arrays, receiver placement, and calibration, these techniques can support indoor positioning applications.

They are useful when facilities need to identify which zones contain mobile equipment without relying only on manual room-by-room searches.

Why AoA / AoD

Key Features & Benefits

  1. 1

    Direction Estimates

    Use compatible antenna arrays and direction-finding signals to estimate device direction.

  2. 2

    Room-to-Zone Visibility

    Build mapped location views using appropriately calibrated receivers.

  3. 3

    BLE Device Ecosystem

    Select tags that support the required Bluetooth direction-finding features.

  4. 4

    Scalable Site Design

    Plan locator placement around building geometry, expected traffic, and coverage requirements.

Use Cases

Popular Applications

In Practice

Practical Example

Customer Need:

A hospital wants to identify which zones contain mobile equipment instead of searching room by room.

Example Deployment:

Compatible direction-finding BLE tags are attached to equipment, and locator arrays help estimate movement between monitored zones.

Typical Architecture:

Direction-Finding BLE Tags → Locator Arrays → Position Engine → Dashboard

Monitoring Data:

  • Estimated zone or position
  • Last-detected time
  • Tag battery level
  • Location confidence

Expected Outcome:

Maintenance and nursing teams can locate tagged equipment more efficiently when the positioning coverage has been verified.

Requirements

Required Hardware & Software

  • Bluetooth tags supporting the required direction-finding features
  • Compatible AoA locators or antenna arrays
  • Calibration tools and location engine
  • Dashboard or platform integration

Support

How BoxTech Supports Your Project

BoxTech works with IoT solution providers, resellers, system integrators, and software partners to align direction-finding hardware with indoor location requirements.

Support may include checking compatibility between tags and AoA locators, coordinating site surveys and calibration, testing sample devices, and connecting location events to partner software, subject to selected products and agreed project scope.

Before You Deploy

What to Validate

Verify tag compatibility, installation and mounting conditions, calibration effort, expected accuracy, and receiver coverage. Test the complete system in the intended environment before confirming performance expectations.
