Execution Walkthrough

Business Problem

Forklift and parcel tracking inside a 50,000 sq ft warehouse was failing due to poor Wi-Fi coverage and metallic obstructions.

Research & Analysis

Conducted RF signal audits, discovering that Wi-Fi signals suffered heavy attenuation through metal racks.

Planning & Architecture

Engineered a LoRaWAN topology with local gateways to transmit sensor telemetry at sub-GHz frequencies.

Architecture & Validation:Formulated a low-power star network where custom ESP32 tracker tags publish coordinate bursts to local LoRa gateways connected to AWS IoT Core.

UX/UI Design

Designed a multi-layer custom PCB using Altium Designer, ensuring appropriate impedance matching and power rails.

Development & Testing

Compiled optimized C++ firmware on ESP32 microchips, employing low-power sleep loops to preserve battery life.

Architecture & Validation:Conducted drop testing on node casing, verified battery drain schedules, and tested coordinate tracking algorithms.

Deployment & CI/CD

Provisioned gateways on AWS IoT Core using Terraform, tracking telemetry coordinates in real time.

Client Benefits

  • Complete RF coverage in warehouses
  • Battery life up to 18 months
  • Seamless AWS IoT backend synchronization
