How RF Tomography Works

When people move in the vicinity of wireless devices, they affect the radio waves traveling between them in various ways. Our technology detects these effects and uses them to understand when people are present or moving in the space. It’s called RF Tomography, and XANDEM’s engineers have decades of experience developing and applying it.

The Advantages

Like other presence and motion detection technologies, RF Tomography is useful in a variety of applications, but there are a few features that set it apart from other solutions:

  • it can be added to existing wireless products via a software update
  • it is compatible with a variety of wireless protocols, including 802.15.4/ZigBee, WiFi, 800/900 MHz proprietary protocols, and more
  • it can cover large areas
  • it can “see” through obstructions, like walls and furniture, making it easy to hide from view
  • it can be deployed quickly

The Applications

The characteristics and capabilities of RF Tomography make it appealing for many types of people sensing. Applications include:

  • room occupancy monitoring for energy efficiency
  • motion detection for security and smart home automation
  • non-contact, less intrusive monitoring of elderly loved ones
