Abstract
Techniques are described for using velocity data to improve the location accuracy of Wi-Fi crowdsourcing. Instead of relying on a reported location of an electronic device that detects a communication node, such as an Access Point (AP), the location of the communication node is adjusted based on the velocity of the electronic device when the electronic device detected the communication node. When a communication node is detected, the electronic device associates the device's location coordinates and associated velocity with the detected communication nodes to create data that is tagged with the identity of the communication nodes. The communication node data is sent to a location service for processing to estimate the location of the communication nodes. The location service may adjust the location of a communication node to be a specified distance from the location of the electronic device. In some cases, the higher the velocity, the greater the specified distance.
