4.3 Geolocation strategies
4.3.1 Main operating modes
The following geolocation policies (geoloc_sensor parameter) are used when the operating mode is either
motion-tracking, permanent-tracking, or start/end tracking.
➢ Wi-Fi only → Only Wi-Fi scans are used for position determination.
➢ GPS only →Only the GPS is used for position determination.
➢ LP-GPS only→ GPS and LP-GPS are used for position determination.
➢ Multimode (Wi-Fi + AGPS + GPS)→ Alternate Wi-Fi, LP-GPS and GPS technologies on failure, with
timeout.
➢ Wi-Fi-GPS only → Wi-Fi then GPS if Wi-Fi fails in one geolocation cycle.
➢ Wi-Fi-LPGPS only → Wi-Fi then LP-GPS if Wi-Fi fails in one geolocation cycle.
➢ Wi-Fi-LPGPS/ Wi-Fi-GPS → Wi-Fi-LPGPS first, then Wi-Fi-GPS if Wi-Fi-LPGPS fails until timeout, then
back to Wi-Fi-LGPS.
Note: The first position is always a Wi-Fi one whatever the chosen geolocation strategy.
4.3.2 Side operations
The following geolocation policies (geoloc_method parameter) are used for periodic-reporting or on-
demand actions.
➢ Wi-Fi only → Only Wi-Fi scans are used for position determination
➢ GPS only →Only the GPS is used for position determination
➢ LP-GPS only→ GPS and LP-GPS are used for position determination
