Abstract
A method and a system for generating a plurality of ranging sound signals for positioning a mobile device are provided. The method includes: each of a plurality of ranging signal generating devices, which are connected to an audio signal cable and are located at different positions in an area, generating a ranging sound signal based on a synchronization signal transmitted on the audio signal cable, whereby location of the mobile device within the area can be obtained based on records of the ranging sound signals made by the mobile device. Accordingly, a plurality of speakers connected in series are able to be controlled to reproduce ranging sound signals for positioning a mobile device.
Claims19
A method for generating a plurality of ranging audio signals for positioning a mobile device, comprising:
- for each of a plurality of ranging signal generating devices that are connected to an audio signal cable and are located at different positions in an area, generating a ranging sound signal based on a synchronization signal transmitted on the audio signal cable, wherein a location of the mobile device within the area is obtained based on records of the ranging sound signals made by the mobile device.
A system for generating a plurality of ranging sound signals for positioning a mobile device, comprising:
- a plurality of ranging signal generating devices that are connected to an audio signal cable and are located at different positions in an area, wherein each of the plurality of ranging signal generating devices is configured to:
- generate a ranging sound signal based on a synchronization signal transmitted on the audio signal cable, wherein a location of the mobile device within the area is obtained based on records of the ranging sound signals made by the mobile device.
