WiFi Routers Used to Produce 3D Images of Humans
Simple Wi-Fi routers can be used to detect and perceive the poses and positions of humans and map their bodies clearly in 3D, a new report has found. With the help of AI neural networks and deep learning, researchers at Carnegie Mellon University were also able to create full-body images of subjects.

Welcome to the OpenWrt Project
Welcome to the OpenWrt Project The OpenWrt Project is a Linux operating system targeting embedded devices. Instead of trying to create a single, static firmware, OpenWrt provides a fully writable filesystem with package management. This frees you from the application selection and configuration provided by the vendor and allows you to customize the device through the use of packages to suit any application.

Wifi is a Sensor
Pulse-Fi measures heartbeat using Wifi signal. It achieves an error of less than 1.5 bpm, matching the performance of conventional sensors.
Research is underway to reliably detect multiple users simultaneously at distances up to 3 meters in various postures with over 100 subjects
How Wi-Fi Signals Can Be Used to Detect Your Heartbeat
Can Wi-Fi signals really track your heartbeat? Dive into the world of Pulse-Fi and find out how it works without wearables.
