01 / The problem
The problem
Investigate how variations in Wi-Fi Channel State Information (CSI) can be acquired, processed and visualized in an experimental system.
02 / Context & contribution
Context & contribution
Computer Engineering undergraduate thesis project. The technical scope below is documented in the public repository; individual changes can be traced through its contribution history.
03 / Engineering choices
Engineering choices
From device to interface
ESP32 firmware for acquisition, a Rust backend for ingestion and processing, and React/TypeScript for visualization.
A separate machine learning pipeline
Python tools train and evaluate models, exporting ONNX artifacts for inference.
Reproducible exploration
Docker Compose and a replay mode make the dashboard explorable without flashing hardware.
Project limitations
An experimental prototype. Results depend on the environment, topology and calibration. It is not a medical device or a validated diagnostic or safety system.
Explore the evidence
The public README documents components, setup, tests and limitations. Local captures, credentials and residential data are excluded from this case study.
An engineering exercise spanning hardware, systems, data and product.
