Millimeter-wave backscatter can simultaneously support high-precision sensing and
massive communication and represent one prominent technical evolution in next-generation …

Due to the poor indoor coverage and positioning accuracy, existing indoor GPS positioning
systems leverages additional RF infrastructure as relay with known position. However, in …

With the rapid development of the Internet of Things, numerous devices have been deployed
in complex environments for environmental monitoring and information transmission, which …

WiFi backscatter localization is a promising technology for the Internet of Things. However,
existing works cannot work well for large-scale and low-cost tags with commodity WiFi …

Precise localization encompassing diverse indoor spaces is the key to immersive interaction
services. In practice, indoor localization often undergoes blind spots as RF is easily blocked …

In this paper, we ask," Can millimeter-wave (mmWave) radars sense objects not directly
illuminated by the radar-for instance, objects located outside the transmit beamwidth, behind …

Acoustic metasurface was recently proposed to enhance the performance of acoustic
communication and sensing. While promising, there are two issues hindering the adoption …

In this work, we present MetaShield, a multi-function configurable metasurface that is affixed
to and surrounds an Access Point (AP). We design MetaShield with three core features:(i) it …
