Commodity Wi-Fi-Based Wireless Sensing Advancements over the Past Five Years

Blog Article

With the compelling popularity of pet calming peanut butter integrated sensing and communication (ISAC), Wi-Fi sensing has drawn increasing attention in recent years.Starting from 2010, Wi-Fi channel state information (CSI)-based wireless sensing has enabled various exciting applications such as indoor localization, target imaging, activity recognition, and vital sign monitoring.In this paper, we retrospect the latest achievements of Wi-Fi sensing using commodity-off-the-shelf (COTS) devices from the past 5 years in detail.

Specifically, this paper first presents the background of the CSI signal and related sensing models.Then, recent studies are categorized from two perspectives, i.e.

, according to their application scenario diversity and the corresponding sensing methodology difference, respectively.Next, this paper points out the challenges faced by Wi-Fi sensing, including domain dependency and sensing range limitation.Finally, three imperative research directions are flex 4 heartworm test highlighted, which are critical for realizing more ubiquitous and practical Wi-Fi sensing in real-life applications.
