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 ...

This paper is about Wi-Fi Backscatter and it’s various variants, a new communication system that enables us to connect RF powered devices, IoT devices as well, and any device using public Wi-Fi. Specifically, it is possible to reuse existing Wi-Fi infrastructure to provide high-speed and low-cost Internet connectivity.

Kalman Filter-Based Data Fusion of Wi-Fi RTT and PDR for Indoor Localization
IEEE Sensors Journal, 2021The Fine Time Measurement (FTM) protocol introduced by IEEE 802.11 includes a new ranging method, named Wi-Fi Round Trip Time (Wi-Fi RTT), which can be used for indoor localization. Pedestrian Dead Reckoning (PDR) can provide accurate pedestrian tracking

Wi-Fi is a wireless-connection technology that enables you to connect computers, printers, game consoles, mobile devices(like your blackberry) and more to the internet. Today we are fortunate to live in a world where Wi-Fi is increasingly ubiquitous. Indeed, it is difficult to go anywhere and not hear about Wi-Fi.

The idea was simple. People had already demonstrated their desire (and willingness to pay) for broadband Internet access at homes and offices. They were apparently falling in love with all things wireless. Wi-Fi hotspots were sprouting up, even if they were mainly confined to coffee shops, airports and hotels. So, the argument ran.
