Technical Overview

How the solution is organized and why the structure matters.

Centimeter-level indoor asset positioning with fixed anchors, mobile tags, live floor maps, geofencing, and movement-history analytics. The technical blueprint separates responsibilities into clear layers so the solution can be tested, explained, extended, and handed over confidently.

System Architecture

Four clear layers keep responsibilities understandable and maintainable.

01

Device and sensing layer

Reads physical inputs, validates sensor values, and manages device-side control logic.

02

Connectivity layer

Moves telemetry and commands through resilient, clearly named messages with reconnect handling.

03

Backend and storage

Validates incoming payloads, stores time-series events, and exposes controlled service endpoints.

04

Monitoring interface

Presents live state, history, alerts, and device health in a responsive dashboard or app.

Technology Stack

The practical role of each technology in this project.

UWB

Ultra-wideband ranging for precise and secure indoor positioning.

ESP32

Connected device controller with sensor interfaces and Wi-Fi support.

Time of Flight

Supports the project's IoT implementation, integration, or evaluation requirements.

MQTT

Lightweight publish/subscribe messaging for device telemetry and commands.

Node.js

Event-driven server runtime for APIs, integrations, and real-time features.

PostgreSQL

Reliable relational data, transactions, indexes, and analytical queries.

Implementation Workflow

A reviewable path from requirements to tested handover.

01

Requirements and constraints

Confirm users, inputs, outputs, acceptance criteria, platform limits, and delivery scope.

02

Architecture and prototype

Validate the highest-risk technical decisions with a small working baseline before full implementation.

03

Implementation and integration

Build in reviewable modules, connect the selected technologies, and document key decisions.

04

Verification and handover

Test expected and failure paths, review outcomes, and prepare technical documentation and guidance.
