A positioning system executes wireless communication with a portable terminal by adopting a radio wave of 1 GHz or higher to determine a position of the portable terminal relative to a vehicle. The positioning system includes a vehicle exterior communication device and a positioning device. The vehicle exterior communication device is disposed at an outer surface portion at least one of a side surface portion or a rear side surface portion of the vehicle, and includes an antenna receiving a wireless signal transmitted from the portable terminal. The positioning device determines whether or not the portable terminal exists at an exterior operating area being a region outside a vehicle compartment within a predetermined operating distance from the vehicle, based on a reception status of the wireless signal received by the vehicle exterior communication device from the portable terminal. The antenna radiates a main polarized wave and a cross-polarized wave.

This document describes a client-server approach for indoor-outdoor detection of an electronic device, and associated systems and methods. A server (104) collects crowdsourced information (140) from devices that detected a plurality of access points. An electronic device (102), performing a wire-less-network scan, detects access points (122) within range and detects sensor data (126) from other sensors (124). The electronic device (102) transmits such information to the server (104). The server accesses the crowdsourced information (140) to determine, per access point (122) detected in the scan, a percentage of total detections of the access point that are accompanied by a GPS signal of a device that detected the access point and an RSS value below which no such GPS signal accompanies the detections. The percentage and the RSS value enable a determination of a probability indicating whether the electronic device (102) is located outdoors, lightly indoors, or deep indoors, which enables the electronic device to trigger a corresponding function.

Described herein are devices, systems, methods, and processes for determining the indoor or outdoor status of an access point (AP) utilizing global navigation satellite system (GNSS) data. In many embodiments, a machine learning model is trained and utilized to distinguish between indoor, outdoor, and partially covered areas based on GNSS data features. In a number of embodiments, geometric inference is utilized to deduce the indoor or outdoor status of the AP from the relative direction of satellites that are detectable or not detectable. In a variety of embodiments, the indoor or outdoor status of the AP is inferred based on an obstacle profile constructed based on satellites that are simultaneously detectable by two or more APs. The standalone solution provides an automated approach for determining the indoor or outdoor status of an AP without relying on external services.

A system for providing real-time always-on location is presented for maintaining the current location of a mobile device, while saving the battery by managing the GPS in a power-saving mode while the device is considered to be stationary. The system also provides a real-time location in an indoor environment where a GPS signal may not be available. Additionally, methods for driving detection are also presented.
