Abstract
Examples are disclosed for a mobile device to determine its location by trilateration with docked mobile devices and, optionally, wireless access points. Locations are determined to within an accuracy of within three feet. The docked mobile devices are at fixed locations such as docked to a docking station. In some examples, a mobile device may perform ranging to the docked mobile devices and fixed wireless stations. Ranging may use a time-of-flight (ToF) process, and may compensate for multipath interference. Trilateration may consider relative accuracies of ranging components. Other examples are described and claimed.
Claims25
An apparatus to locate an indoor position, comprising:
- a processor circuit for a mobile device;
- a gather component to be executed by the processor circuit to gather identification information from one or more devices capable of wirelessly communicating with the mobile device;
- a range component to be executed by the processor circuit to determine ranges between the mobile device and the one or more devices based on a ranging process utilizing wireless signals, wherein at least one of the one or more devices comprises a docked mobile device;
- and
- a trilateration component to be executed by the processor circuit to locate a position of the mobile device based on the determined ranges to the one or more devices.
A method to locate an indoor position, comprising:
- gathering, by a processor circuit for a mobile device, identification information from one or more devices capable of wirelessly communicating with the mobile device;
- ranging, by the processor circuit, to determine ranges between the mobile device and the one or more devices based on a ranging process utilizing wireless signals, wherein at least one of the devices comprises a docked mobile device;
- and
- calculating, by the processor circuit, a location of the mobile device from the determined ranges.
A system to locate an indoor position, comprising:
- a processor circuit;
- a memory coupled to the processor circuit;
- a gather component, stored in the memory, to be executed by the processor circuit to gather identification information from one or more devices capable of wirelessly communicating with the mobile device;
- a range component, stored in the memory, to be executed by the processor circuit to determine ranges between the mobile device and the one or more devices based on a ranging process utilizing wireless signals, wherein at least one of the devices comprises a docked mobile device;
- and
- a trilateration component, stored in the memory, to be executed by the processor circuit to calculate a location of the mobile device based on the determined ranges to the one or more devices;
- a transceiver coupled to the processor;
- and
- an antenna coupled to the transceiver and configured to operate at a defined set of frequencies.
