Abstract
Examples of the disclosure relate to apparatus (101) for positioning mobile devices (105). The apparatus (101) comprises means for: obtaining a time of arrival of at least one audio signal (131) at a mobile device (105), wherein the audio signal (131) is generated with a photoacoustic effect; and using the time of the arrival of the audio signal (131) to estimate a location of the mobile device (105).
Claims18
An apparatus comprising at least one processor;
- and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to:
- obtain an emitting time of at least one audio signal, wherein the at least one audio signal is generated with a photoacoustic effect by at least one light source at a known location;
- obtain a time of arrival of the emitted at least one audio signal in relation to a mobile device, wherein the emitted audio signal is captured at the mobile device;
- and
- estimate a location of the mobile device based on the emitting time and the time of arrival.
2 more elements
A method comprising:
- obtaining an emitting time of at least one audio signal, wherein the at least one audio signal is generated with a photoacoustic effect by at least one light source at a known location;
- obtaining a time of arrival of the emitted at least one audio signal in relation to a mobile device, wherein the emitted at least one audio signal is captured at the mobile device;
- and
- estimating a location of the mobile device based on the emitting time and the time of arrival.
1 more element
A mobile apparatus comprising at least one processor;
- and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the mobile apparatus at least to:
- detect at least one emitted audio signal, wherein the at least one audio signal is generated with a photoacoustic effect at a known location;
- and
- enable the detected emitted at least one audio signal to be used to estimate a location of the mobile apparatus.
1 more element
A method comprising:
- detecting, by a mobile apparatus, at least one emitted audio signal, wherein the at least one audio signal is generated with a photoacoustic effect at a known location;
- and
- enabling the detected emitted at least one audio signal to be used to estimate a location of the mobile apparatus.
