Abstract
A facility for determining the location of a mobile device when a location determination of a desired accuracy is desired. If available, the facility determines the location of the mobile device using a device-based technique or using a location determination technique that is accessible over a macronetwork. Macronetworks are networks that are designed to cover relatively large areas. If a location determination technique of desired accuracy is not available on the device or over a macronetwork, the facility attempts to use a location determination technique that is accessible over a micronetwork to determine the location of the mobile device. Micronetworks are networks that are designed to cover smaller areas. By forcing a switch from a macronetwork-based location determination technique to a micronetwork-based location determination technique, the facility ensures that a location determination is made for the mobile device of a desired accuracy, time to fix (TTF), and/or yield.
