How are Blix Traffic sensors able to measure a specific area?

The Blix Traffic sensor detects a WiFi ping which can cover quite a large area (up to 3,000 m2 or 10,000 sf). When a sensor is initially installed, it is “calibrated” to calculate what portion of the total WiFi coverage area is required to be measured. This calibration is further tuned and refined on an ongoing basis.

For example, if a Blix Traffic sensor is placed centrally in a retail store with a floor area of 400 m2 (or 1200 sf), then the sensor is calibrated to only measure this retail space, not it’s entire range.
