A solution to this issue starts with the mobile client detecting the proximity of a BLE tag based on RSSI signal strength. If the mobile client device becomes stationary (determined via motion sensor within the mobile client), within range of a BLE tag's signal, the mobile client initializes mapping of the data into a lookup table with the BLE tag MAC address, a start timestamp, and an end timestamp. The total dwell time is then calculated by the difference between the end timestamp and the start timestamp. If the mobile client remains available in proximity of the BLE tag and the mobile client is stationary, the process keeps on repeating and updates the total dwell time of the user in lookup table. The dwell time detection process stops when the mobile client leaves the proximate area surrounding the BLE tag.
