TL;DR: SpotFi only uses information that is already exposed by WiFi chips and does not require any hardware or firmware changes, yet achieves the same accuracy as state-of-the-art localization systems.

TL;DR: It is shown that it is possible to design devices and WiFi APs such that the WiFi AP in the process of transmitting data to normal WiFi clients can decode backscatter signals which the devices generate by modulating information on to the ambient WiFi transmission.

TL;DR: HitchHike is presented, a low power backscatter system that can be deployed entirely using commodity WiFi infrastructure, and its key invention is a novel technique called codeword translation, which allows a backscattering tag to embed its information on standard 802.11b packets.

TL;DR: The design and implementation of WiDeo is presented, a novel system that enables accurate, high resolution, device free human motion tracing in indoor environments using WiFi signals and compact WiFi radios.

TL;DR: This paper presents PinPoint, a technique for localizing rogue interfering radios that adhere to standard protocols in the inhospitable ISM band without any cooperation from the interfering radio, and compares PinPoint with the best known prior RSSI and MUSIC-AoA based approaches.
