Abstract
An audio device capable of intelligently switching between multiple antennas is provided. The audio device receives a wireless signal by a default receiving antenna, determines signal quality metrics of the wireless signal received by various antennas, compares the signal quality metrics of the wireless signal received by the various antennas, and selects a receiving antenna from the various antennas to receive the wireless signal based on the comparison of the signal quality metrics of the wireless signal received by the various antennas.
Claims20
An audio device comprising:
- at least one speaker;
- a plurality of antennas to receive a wireless signal from a source;
- a controller coupled to the plurality of antennas and the at least one speaker, the controller including at least one processor coupled to a memory;
- and
- an antenna manager component executable by the at least one processor and configured to:
- receive the wireless signal by a default receiving antenna, the default receiving antenna being one antenna of the plurality of antennas;
- determine one or more signal quality metrics of the wireless signal received by at least two antennas of the plurality of antennas over a period of time;
- compare the one or more signal quality metrics of the wireless signal received by each of the at least two antennas over the period of time;
- and
- select a receiving antenna from the at least two antennas to receive the wireless signal based on the comparison between the one or more signal quality metrics of the wireless signal received by each of the at least two antennas.
A method of antenna switching in an audio device comprising:
- receiving a wireless signal from a source device by a default receiving antenna from a plurality of antennas;
- determining one or more signal quality metrics of the wireless signal received by at least two antennas of the plurality of antennas over a period of time;
- comparing the one or more signal quality metrics of the wireless signal received by each of the at least two antennas;
- and
- selecting a receiving antenna from the at least two antennas to receive the wireless signal based on the comparison between the one or more signal quality metrics of the wireless signal received by each of the at least two antennas.
An antenna switching system comprising:
- a plurality of antennas to receive a wireless signal from a source;
- a plurality of controllers connected in a network, each controller of the plurality of controllers being coupled to at least one antenna of the plurality of antennas and including at least one processor coupled to a memory;
- and
- an antenna manager component, executable by the at least one processor of at least one controller of the plurality of controllers, configured to:
- receive the wireless signal by a default receiving antenna, the default receiving antenna being one antenna of the plurality of antennas;
- determine one or more signal quality metrics of the wireless signal received by at least two antennas of the plurality of antennas over a period of time;
- compare the one or more signal quality metrics of the wireless signal received by each of the at least two antennas;
- and
- select a receiving antenna from the at least two antennas to receive the wireless signal based on the comparison between the one or more signal quality metrics of the wireless signal received by each of the at least two antennas.
