Abstract: Disclosed is an apparatus and method for synchronization of sensing operations performed by a plurality of devices. The method may include collecting sensing capabilities of one or more connected devices that are communicably coupled with a central device. Each connected device may include one or more sensors, and the sensing capabilities may include at least sensor type and sensing interval for each sensor. The method may also include coordinating sensing operations performed by the central device and the one or more connected devices.

Abstract: A mobile device synchronously scans different terrestrial networks for positioning measurements to align the scans in time. With minimal time difference between the scans, the positioning measurements from the different terrestrial networks may be used for crowdsourcing or position determination. The mobile device may synchronously scan a wireless wide area network (WWAN) and a local area wireless network so that positioning measurement derived from the scans are aligned in time. A local area wireless network is, e.g., a wireless local area networks (WLANs) or wireless personal area network (WPANs) but does not include cellular networks or satellite networks. The scans may be scheduled at a hardware level to ensure tight synchronization with near-zero time difference between the scans. Alternatively, the scans may be synchronized at a software level with only scans that occur within a time difference threshold from each other are used for crowdsourcing or positioning.
