  • Publication number: 20190223144
    Abstract: Embodiments relate to location determination of computing devices. An example system includes a processor configurable to identify, from a first device, a second device transmitting wireless signals to the first device. The processor is configurable to determine, from the first device, a signal level of the wireless signals received by the first device from the second device. The processor is configurable to identify, from the first device, a third device transmitting wireless signals to the second device. The processor is configurable to determine, from the first device, a signal level of the wireless signals received by the second device from the third device. The processor is configurable to derive a location status of the first device based on the identification of the second and third devices and the signal levels of the wireless signals received by the first and second devices from the second and third devices, respectively.

  • Publication number: 20190215797
    Abstract: Embodiments relate generally to determining a location of a computing device. An example system may include a processor. The processor may be configurable to receive a current state of the computing device. The current state may be a charging or non-charging state. The charging state may be a state in which an energy source of the computing device is connected to and/or being charged by an external energy source. The non-charging state may be one in which the energy source is not connected to and/or not being charged by the external energy source. The processor may be configurable to receive information pertaining to wireless signals of a WLAN. The information may include an identification of a first transmitting device. The processor may also be configurable to derive a location status of the computing device based on the current state of the computing device and identification of the first transmitting device.

The processor may be configurable to receive information pertaining to wireless signals of a WLAN. The information may include an identification of a nearest transmitting device. The processor may also be configurable to derive a location status of the computing device based on the current state of the computing device and identification of the nearest transmitting device.
