Abstract
Official abstract text for this publication.
Techniques are provided for providing a processing delay estimate of an access point, or turnaround calibration function (TCF), associated with round trip time (RTT) measurements. Mobile devices, access points, and/or other systems can utilize these techniques to derive processing delay from the RTT measurements. Crowdsourcing can also be used to help increase the accuracy of the processing delay estimate, which can be propagated to multiple devices.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for using a mobile device to provide a processing delay estimate associated with round trip time (RTT) measurements of a wireless access point, the method comprising: obtaining, at the mobile device, a plurality of received signal strength indication (RSSI) measurements measuring a signal strength of the wireless access point at the mobile device; obtaining a plurality of RTT measurements comprising an RTT measurement corresponding to each RSSI me…
