WiFi signals can measure heart rate—no wearables needed
Engineers prove their technique is effective even with the lowest-cost WiFi devices

I have a lot of devices (~15) on my home wifi network. Around me are also 10-15 neighboring wifi networks as well as nearly 30 bluetooth devices of various origins.
I find it incredibly funny that using wireless bluetooth headphones throws me back to the vinyl record days where you hear constant popping, cracking and skipping.
All this fancy technology just to come full circle. 😄
Luckily, my particular pair came with an optional wire. 🎧

Let's get the basics right for my laptop config:
- encryption during install, not jumping through hoops in partitioning
- wifi easily selected during install
- preferably non-systemd
- software not too outdated
Exactly where FreeBSD could shine, were it not for an unsupported wifi adapter 🤔

Domino: Dominant Path-based Compensation for Hardware Impairments in Modern WiFi Sensing
WiFi sensing faces a critical reliability challenge due to hardware-induced RF distortions, especially with modern, market-dominant WiFi cards supporting 802.11ac/ax protocols. These cards employ sensitive automatic gain control and separate RF chains, introducing complex and dynamic distortions that render existing compensation methods ineffective. In this paper, we introduce Domino, a new framework that transforms channel state information (CSI) into channel impulse response (CIR) and leverag…

WiFi-based Global Localization in Large-Scale Environments Leveraging Structural Priors from osmAG
Global localization is essential for autonomous robotics, especially in indoor environments where the GPS signal is denied. We propose a novel WiFi-based localization framework that leverages ubiquitous wireless infrastructure and the OpenStreetMap Area Graph (osmAG) for large-scale indoor environments. Our approach integrates signal propagation modeling with osmAG's geometric and topological priors. In the offline phase, an iterative optimization algorithm localizes WiFi Access Points (APs) by…

Graph-based Fingerprint Update Using Unlabelled WiFi Signals
WiFi received signal strength (RSS) environment evolves over time due to movement of access points (APs), AP power adjustment, installation and removal of APs, etc. We study how to effectively update an existing database of fingerprints, defined as the RSS values of APs at designated locations, using a batch of newly collected unlabelled (possibly crowdsourced) WiFi signals. Prior art either estimates the locations of the new signals without updating the existing fingerprints or filters out the…

It can (at the load I was giving it there) run my laptop, camera, phone and wifi router for about 10 hours.

Dynamic Campus Origin-Destination Mobility Prediction using Graph Convolutional Neural Network on WiFi Logs
We present an integrated graph-based neural networks architecture for predicting campus buildings occupancy and inter-buildings movement at dynamic temporal resolution that learns traffic flow patterns from Wi-Fi logs combined with the usage schedules within the buildings. The relative traffic flows are directly estimated from the WiFi data without assuming the occupant behaviour or preferences while maintaining individual privacy. We formulate the problem as a data-driven graph structure repre…

The portable air conditioner unit we have in the bedroom is reasonably advanced: it has WiFi connectivity, a remote control, and the ability to switch between heating and cooling. It's annoying, though, that you can only set a sleep timer on the unit itself, which isn't great when you're all nice and comfy in bed. It also takes several button presses when you're there. Fixed thanks to #HomeAssistant, meaning it can be set through the app or voice 😄

Well, turns out that my laptop is even less portable than I thought. On top of dead battery, I've just discovered that the wifi card goes nuts when I move the laptop a little, which in the best case results in kernel panic, and in the worst in plain old hardware hang.
