Abstract: The present disclosure is directed to a system and method for providing improved routing options using connectivity data. The method includes receiving, from a plurality of user devices, network connectivity data, the network connectivity data including associated geographic data. The method includes generating, using a machine learned model, one or more connectivity metrics for a plurality of geographic areas based on the network connectivity data. The method includes receiving a navigation request from a first user device, the navigation request including a destination location, an origin location, and one or more request parameters. The method includes determining a route to the destination location from the origin location that meets one or more connection criteria for the route based, at least in part, on connectivity metrics associated with one or more geographic areas along the route. The method includes transmitting data describing the route to a user device for display.

Abstract: This document describes techniques, apparatuses, and systems for adaptive wireless transmitter power control for GNSS interference mitigation. This document addresses interference degradation in GNSS operations of computing devices due to integration of a variety of radio interference aggressors in the same platform. A GNSS subsystem is disclosed that may assert power back-off requests to reduce the power of one or more RAT transmitters and limit signal degradation during GNSS subsystem operations. Qualities of the satellite signals received at the GNSS subsystem may be analyzed to determine if it is appropriate to assert or deassert the power back-off requests. In this way, the described techniques, apparatuses, and systems for adaptive wireless transmitter power control for GNSS subsystems may adaptively manage GNSS subsystem operations and other RATs to reduce GNSS signal degradation due to interference.
