KNOWLEDGE BASE / FIELD NOTES

# Positioning Technologies.

Understand the signals behind indoor location. Explore deployment architectures, measurement methods and the hardware decisions that turn radio observations into useful position data.

ILLUSTRATED GUIDES HARDWARE SELECTION INDUSTRIAL RTLS

GUIDE 01 / BLUETOOTH

## Introduction to Bluetooth Positioning

Compare Bluetooth base stations, fixed beacons, AoA direction finding and ToF / Channel Sounding. Four original diagrams explain the signal paths, with a comparison table and practical deployment questions.

GUIDE 03 / WAREHOUSE SELECTION

## BLE AoA vs UWB: Which Should You Choose for Warehouse Positioning?

Choose a warehouse positioning architecture around the decisions your operation needs to make, then compare complete systems under the same site conditions.

GUIDE 02 / ULTRA-WIDEBAND

## UWB Positioning Technology

Understand TDoA, ToF / two-way ranging and PDoA / AoA. Four original diagrams explain timing, distance, direction and anchor placement for indoor personnel and asset tracking.

## Learn the method before choosing the device

A gateway, beacon and tag describe device roles. RSSI, angle of arrival and ranging describe measurements. Understanding both helps you specify compatible transmitters, receivers and a positioning engine.

## Connect theory to your application

After reviewing a technology, compare site conditions, mounting geometry, battery needs and integration interfaces. Product capability and operating limits come from the model specification and a representative site trial.
