Sensing solution using Wi-Fi radio wavepowered by the TRM  (WirelessAI™) of Origin Wireless™


Taking advantage of Wi-Fi radio wave as a sensor

STMicroelectronics eForce Ubiquitous Murata

We can detect changes in the environment by using real time sensing with a combination of. TRM(WirelessAITM)technology of Origin WirelessTM and Murata’s wireless module technology. This technology is enabled by the channel state information (CSI) and H-matrix data provided by Marvell’s IC firmware

Applications using TRM Technology are TRM sensing and TRM Positioning.

We will introduce and demonstrate both ”Presence Monitoring" and "Breath Monitoring" as applications of TRM sensing in this video.


  • We can detect changes in the environment and identify the location of source of the changes with the reach of Wi-Fi radio wave indoors because we use multi path of the Wi-Fi wave.
  • Stress free monitoring for indoors comes true with no sensor, no camera and no wearable devices.


  • Changes in the environment are able to be detected from changes in the Wi-Fi radio wave reflections.
  • By reversing the reflection path, the location of the source can be determined.
  • Sensing is available within the reach of Wi-Fi radio


  • Life Log as a Service

  • Presence monitoring

  • Sleep monitoring

  • Fall detection
    (under developing)

  • Asset tracking


System configuration example
