Tracking Human Mobility Using WiFi Signals
We study six months of human mobility data, including WiFi and GPS traces recorded with high temporal resolution, and find that time series of WiFi scans contain a strong latent location signal. In fact, due to inherent stability and low entropy of human mobility, it is possible to assign location to WiFi access points based on a very small number of GPS samples and then use these access points...
متن کاملVisualizing Wifi using the Wifi Camera
These images were created using a " Wifi Camera " custom designed by Somlai-Fischer, Sjölén and Haque (information available at ). It makes a use of a directional 2.4Ghz wifi antenna mounted on servos scanning an environment at varying resolutions, measuring signal strength of all present networks to generate an image of the wifi " view " of the space. A ...
متن کاملSpectroscopic Imaging Using Terahertz Time-Domain Signals
Imaging systems based on terahertz time-domain spectroscopy offer a range of unique modalities due to the broad bandwidth, sub-picosecond duration, and phasesensitive detection of the THz pulses. Furthermore, an exciting possibility exists to combine spectroscopic characterization and/or identification with imaging because the radiation is broadband in nature. In order to achieve this, novel me...
متن کاملDevice-Free Passive Identity Identification via WiFi Signals
Device-free passive identity identification attracts much attention in recent years, and it is a representative application in sensorless sensing. It can be used in many applications such as intrusion detection and smart building. Previous studies show the sensing potential of WiFi signals in a device-free passive manner. It is confirmed that human's gait is unique from each other similar to fi...
متن کاملCatching Whales and Minnows Using WiFiNet: Deconstructing Non-WiFi Interference Using WiFi Hardware
We present WiFiNet— a system to detect, localize, and quantify the interference impact of various non-WiFi interference sources on WiFi traffic using commodity WiFi hardware alone. While there are numerous specialized solutions today that can detect the presence of non-WiFi devices in the unlicensed spectrum, the unique aspects of WiFiNet are four-fold: First, WiFiNet quantifies the actual inte...
