    Abstract: Systems, apparatus and methods for determining whether to use an indoor map or an outdoor map based on local area network (LAN) signals from access points (APs) are disclosed. If only weak AP signals belonging to a location content identifier (LCI) are received, prior art systems display an indoor map associated with the LCI. An improvement herein further determines a quality of AP signals and/or wide area network (WAN) signals before determining whether to display the indoor map or an outdoor map.

    CPC classification number: G01C21/3446

    Abstract: Methods and apparatus for route selection to a destination may include receiving a starting point and one or more destinations, and transmitting a request to a server for routes associated with the starting point and the one or more destinations. Additionally, the methods and apparatus may include receiving, from the server, a plurality of routes to the one or more destinations. Furthermore, the methods and apparatus may include selecting a route from the plurality of routes based at least on one or more reliability parameters associated with each route of the plurality of routes, the one or more reliability parameters comprising a likelihood of determining a position location along each route, the likelihood being based at least on detectability of features in each route by one or more object detection modalities.

    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: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for a ranging protocol between two wireless local area network (WLAN) devices. In one aspect, the ranging protocol may be adjusted based on channel quality of a wireless medium between the WLAN devices. For example, a quantity of ranging frames and bandwidth for the ranging frames may be adjusted based on the channel quality. In some implementations, the channel quality may be determined using setup messages for the ranging protocol without a wireless association between the WLAN devices. The ranging protocol may be useful for range determination in an indoor environment where a WLAN is deployed. In some implementations, the ranging protocol may be used to determine a location of a WLAN device.
