Abstract
Systems and methods are provided for optimizing, e.g., speeding up, fine time measurement (FTM) scanning by dedicating a radio of a network element, such as an access point (AP), to performing FTM scanning at a high frequency. The high frequency FTM scanning provides quicker results regarding location determination of the network element as compared to conventional FTM scanning, which is performed merely as a background process. The high frequency FTM scanning can be performed in accordance with configurable FTM scan parameters.
Claims20
A method comprising:
- receiving at an access point (AP) of a plurality of neighboring APs, fine timing measurement (FTM) scan parameters;
- dedicating a radio of the AP to performing FTM scanning of the plurality of neighboring APs;
- performing FTM scans of the plurality of neighboring APs in accordance with the received FTM scan parameters using the dedicated radio;
- reporting results of the FTM scans in near real-time to a location-requesting entity or application to determine a location of the AP.
A system, comprising:
- a processor;
- and
- memory comprising instructions that when executed, cause the processor to:
- change a radio's operation mode to a dedicated fine timing measurement (FTM) scanning mode, and tune the radio to a specified channel;
- create a service set identifier (SSID) profile for the radio, hide a corresponding SSID string, and set an FTM response flag in a beacon;
- configure the radio to perform FTM scanning in accordance with scan parameters;
- advertise FTM support with the beacon, and perform the FTM scanning in accordance with the scan parameters by responding to FTM requests over the specified channel;
- and
- deny any client device request received by the radio.
A network element, comprising:
- a first radio;
- a second radio;
- a processor;
- and
- memory comprising instructions that when executed, cause the processor to:
- dedicate the first radio to performing high-frequency fine timing measurement (FTM) scanning for enabling a location of the network element to be determined by a location-requesting entity or application;
- receive one or more FTM scan parameters;
- perform the high-frequency FTM scanning using the first radio in accordance with the one or more FTM scan parameters;
- and
- provide client device communication support with the second radio.
