  author={Daniel Halperin and Wenjun Hu and Anmol Sheth and David Wetherall},
  journal={Comput. Commun. Rev.},
We are pleased to announce the release of a tool that records detailed measurements of the wireless channel along with received 802.11 packet traces. It runs on a commodity 802.11n NIC, and records Channel State Information (CSI) based on the 802.11 standard. Unlike Receive Signal Strength Indicator (RSSI) values, which merely capture the total power received at the listener, the CSI contains information about the channel between sender and receiver at the level of individual data subcarriers… 
HitchHike: Practical Backscatter Using Commodity WiFi
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.
Practical Implementation of Physical-Layer Key Generation using Standard WLAN Cards and Performance Evaluation
  • 2017
The properties of the physical layer in wireless networks are exploited to generate one-time pads which are subsequently used for secure communication between legitimate users. Previous measurement
WLAN Device Fingerprinting using Channel State Information (CSI)
This work shows that radio-metrics such as amplitude and phase can be used to create a unique fingerprint of a wireless device, based on as little as 100 CSI packets per device collected with an off-the-shelf Wi-Fi card.
WS-WiFi: Wired Synchronization for CSI Extraction on COTS-WiFi-Transceivers
This article is the first to investigate the temperature-dependent behavior of the CSI phase across multiple devices, and shows that with only a single received packet and minor hardware adjustments, it is able to obtain the AoA of a WiFi transmitter with a mean absolute error.
T-SIMn: Towards a Framework for the Trace-Based Simulation of 802.11n Networks
With billions of WiFi devices now in use, and growing, combined with the rising popularity of high-bandwidth applications, such as streaming video, demands on WiFi networks continue to rise. To
Identifying signal source using channel state information in wireless LANs
The feasibility of identifying signal source in wireless LANs using channel state information obtained from preambles using CSI-based source identification method is studied, and can be used along with schemes such as BSS coloring included in the IEEE 802.11ax standard for highly efficiency WLANs.
Exploiting Residual Channel for Implicit Wi-Fi Backscatter Networks
A flicker detector is proposed that achieves per-symbol in-band backscatter by exploiting residual channel of Wi-Fi packets and shows robust performance without any modification on the hardware and any side effect on wireless channels.
MonoPHY: Mono-stream-based device-free WLAN localization via physical layer information
MonoPHY leverages the physical layer information of WiFi networks supported by the IEEE 802.11n standard to provide accurate DF localization with only one stream and leverages both the low-level Channel State Information and the MIMO information to capture the human effect on signal strength.
SDR receiver using commodity wifi via physical-layer signal reconstruction
SDR-Lite is presented, the first zero-cost, software-only software defined radio (SDR) receiver that empowers commodity WiFi to retrieve the In-phase and Quadrature of an ambient signal and shows that the reconstructed signal closely reassembles the original ambient signal.
ZIGFI: Harnessing Channel State Information for Cross-Technology Communication
This paper proposes ZigFi, a novel CTC framework that enables direct communication from ZigBee to WiFi, and builds a generic model through experiments, which describes the relationship between the Signal to Interference and Noise Ratio (SINR) and the symbol error rate (SER).


Predictable 802.11 packet delivery from wireless channel measurements
It is shown that, for the first time, wireless packet delivery can be accurately predicted for commodity 802.11 NICs from only the channel measurements that they provide, and the rate prediction is as good as the best rate adaptation algorithms for 802.
ACM SIGCOMM computer communication review
The Internet is going mobile and wireless, perhaps quite soon, with a number of diverse technologies leading the charge, including, 3G cellular networks based on CDMA technology, a wide variety of what is deemed 2.5G cellular technologies (e.g., EDGE, GPRS and HDR), and IEEE 802.11 wireless local area networks (WLANs).
802.11 with multiple antennas for dummies
This tutorial provides a brief introduction to multiple antenna techniques, and describes the two main classes of those techniques, spatial diversity and spatial multiplexing.
