Why the Same Fall Radar Behaves Differently in a Bathroom and an Open Office
A customer mounts a fall detection radar in an office corner, walks around, lies down on the floor, and gets a reliable alarm. Another customer mounts the same radar in a bathroom and gets a different result. Neither radar is faulty. The radar is tuned for one of those two rooms.

A customer places a fall detection radar in an office corner, moves around, lies down on the floor, and receives a dependable alarm. Conversely, another customer installs the same radar in a bathroom and encounters a different outcome. Neither radar proves defective. The radar is calibrated for one of those two environments. This article elucidates why the radar is optimized for a bathroom, which three design decisions stem from this calibration, and the implications when the radar is relocated to an open space.
It caters to anyone assessing this radar and to those who have tested it outside a bathroom and are puzzled by the behavior change.
A bathroom presents a small, enclosed space with a single entryway, hard, reflective surfaces, and a limited number of predictable moving objects. Such a combination is rare, and it offers both advantages and challenges. The same traits that make a bathroom hard — tiled walls, a waterproof floor, a toilet, an extractor fan, a shower curtain — also facilitate precise radar calibration.
A room of approximately 2 m × 3 m (5 to 6 m²), bounded by one door and hard walls, provides the radar with a confined area and a known entry and exit path, enabling optimized tuning. This tuning is an intentional design choice, not a limitation imposed upon the product.
