RFID and Infrared-based RTLS TechnologyActive RFID
Active RFID uses battery-powered tags/badges to communicate the tag's identification to the sensors. RFID signals have the ability to pass through walls, which makes it suitable for assistance requests from patients, residents, and staff which may not be in direct view of the reader. Key attributes of the technology:
- Signals pass through walls and floors
- Not suitable for room-level locating
- Sensor range of approximately a 50-foot radius
Infrared (IR)
Infrared technology is one of two technologies that provide the system's room-level location-sensing capabilities. The technology has been in use for decades in several common devices, such as television remote controls. Key attributes of the technology:
- Requires line-of-sight
- Does not penetrate walls, which provides the room-level location accuracy
- Sensors range of approximately a 15-foot radius, but can be adjusted to be larger or narrower
