Abstract: Devices, systems, methods, and processes for accurately determining a location of a device are described herein. The device may receive Global Navigation Satellite System (GNSS) data from two satellites in two time periods. The device can determine two pseudo range differences corresponding to the two satellites. The device may further determine two contours based on the two pseudo range differences. An overlap between the two contours may be utilized by the device to determine the location. The device can also determine the location of the device based on a contour and an estimated location. The device may utilize a Global Positioning System (GPS) database, an Access Points (AP) database, or one or more servers to retrieve the estimated location. The device can further configure an operating frequency and an output power based on the location in real-time.

Abstract: Improved Radio Frequency (RF) performance by optimizing temperature may be provided. A plurality of heatmaps may be created associating a plurality of component heat characteristics, of a plurality of components of a device, with a plurality of pre-defined performance trade-off states. Next, a shortest path through the plurality of pre-defined performance trade-off states may be determined. The device may then be placed in successive ones of the plurality of pre-defined performance trade-off states according to the determined shortest path until a Transmit (TX) performance target is met.

Abstract: Disclosed are systems, apparatuses, methods, and computer-readable media for identifying a locations of a network entities within a network. A method for identifying a location of an (AP) includes receiving a first location measurement associated with a first measurement variant and a second location measurement associated with a second measurement variant from a first AP; receiving a third location measurement associated with the first measurement variant and a fourth location measurement associated with the second measurement variant from a second AP; determining weights associated with the location measurements; determining a first location associated with the first AP and a second location associated with the second AP based on a first weight, a second weight, a third weight, and a fourth weight; determining a confidence of the first location based on a comparison of the first location measurement and the second location measurement.

Abstract: In one embodiment, a device may obtain sensor measurements from an environmental sensor of an access point. The device may obtain traffic telemetry data regarding network traffic handled by the access point. The device may generate, based on the sensor measurements and the traffic telemetry data, a sampling configuration of the environmental sensor of the access point. The device may cause the access point to collect additional sensor measurements from its environmental sensor according to the sampling configuration.

Abstract: Collaborative geolocation estimation may be provided. A plurality of access points (APs) may receive a geolocation estimation request from a controller. Next, one or more of the plurality of APs may receive signals from a plurality of satellites. The controller may then receive the signals from the plurality of APs. The controller may determine a collaborative geolocation estimation using the signals, wherein, when relative locations of the APs are available, determining the geolocation estimation comprises applying the relative locations. One or more of the plurality of APs may receive the geolocation estimation from the controller.
