Abstract

An apparatus obtains a fingerprint that has been collected by at least one mobile device for use in supporting location of other mobile devices. Each fingerprint comprises a result of a measurement of a radio signal of at least one communication node at a particular location and an indication of said particular location. The device estimates values ​​of parameters defining a radio model for the at least one communication node based on the obtained fingerprint. The device determines the quality of the radio model. The apparatus generates data for feedback to a user of the at least one mobile device based on the determined quality of the radio model.

Description

technical field [0001] The present invention relates to the field of positioning, and more particularly to supporting radio model quality assurance. Background technique [0002] Positioning techniques based on satellite signals, which are mainly used outdoors, are generally not suitable for providing satisfactory performance when used indoors because the satellite signals of Global Navigation Satellite Systems (GNSS) such as the Global Positioning System (GPS) are not sufficient Penetrates walls or roofs strongly for adequate indoor signal reception. Therefore, these positioning technologies cannot provide indoor performance that would enable a seamless, equivalent and accurate outdoor and indoor navigation experience. [0003] Consequently, several specialized solutions dedicated to indoor positioning have been developed and commercially exploited over the past few years. Examples include pseudolites (which are ground-based GPS-like short-range beacons) based schemes, ul...
