Wi-Fi has traditionally been considered a power-consuming communication system and has not been widely adopted in the sensor network and Internet of Things (IoT) space. We introduce Passive Wi-Fi that demonstrates that one can generate 802.11b transmissions using backscatter communication, while consuming 3-4 orders of magnitude lower power than existing Wi-Fi chipsets. Passive Wi-Fi transmissions can be decoded on any Wi-Fi device including routers, mobile phones and tablets. Our experimental… 
Battery-free Wi-Fi: Making Wi-Fi transmission simpler and practical
TLDR
The solution proposed not only has the advantages of system simplification, low cost, and no need for battery, but also enables the rapid development of Wi-Fi IoT products with existing commercial microcontrollers.
Ultra-low power micro Wi-Fi scattering communication device
TLDR
The communication test and power consumption measurement results show that μWi-Fi can generate signals conforming to the IEEE802.11b standard, which can be received and forwarded by universal Wi-Fi routers and has a simple composition and low cost, which is very helpful for the rapid development of Wi-fi IoT products.
An experimental study of secret key generation for passive Wi-Fi wearable devices
TLDR
This paper describes a method to generate a shared secret key based on wireless channel characteristics in the passive Wi-Fi scenario where the two parties are using dual frequencies.
Exploiting Residual Channel for Implicit Wi-Fi Backscatter Networks

Inter-Technology Backscatter: Towards Internet Connectivity for Implanted Devices
TLDR
Inter-technology backscatter is introduced, a novel approach that transforms wireless transmissions from one technology to another, on the air, thus enabling the vision of Internet connected implanted devices.
A Low-Power Backscatter Modulation System Communicating Across Tens of Meters With Standards-Compliant Wi-Fi Transceivers
TLDR
The first integrated circuit designed to enable low-power backscatter communication with commodity Wi-Fi transceivers is presented, which operates by receiving a series of packets generated from aWi-Fi access point, which feeds into a low- power energy-detecting wake-up receiver that determines when backscattering communication should commence.
12.2 Improving the Range of WiFi Backscatter Via a Passive Retro-Reflective Single-Side-Band-Modulating MIMO Array and Non-Absorbing Termination
TLDR
This work has suggested piggybacking baseband signals from the loT device directly on top of incident Wi-Fi signals generated by access points (APs) viaWi-Fi-compatible backscatter modulation, but the major limitation of this approach is range.
Channel Independent Wi-Fi Backscatter Networks
TLDR
This work designs a backscatter receiver accepting Wi-Fi frames on the listening channel as well as adjacent channels, and proposes a method that translates the error vectors of each subcarrier into a back scatter frame.
Passive-ZigBee: Enabling ZigBee Communication in IoT Networks with 1000X+ Less Power Consumption
TLDR
