Dual band wireless communications for multiple concurrent audio streams

A system, comprising:

• a first wireless interface that communicates using a short-range device-to-device communication protocol using a first frequency band;
• a second frequency-shifted wireless interface that communicates using the short-range device-to-device communication protocol on a frequency-shifted communication band outside of the first frequency band;
• and
• a processing system, comprising one or more processors, configured to:
• receive a first audio stream from a first audio source via the second frequency-shifted wireless interface using the short-range device-to-device communication protocol;
• receive a second audio stream from a second audio source via the first wireless interface using the short-range device-to-device communication protocol;
• and
• output the first audio stream and the second audio stream via one or more speakers.

A method of performing wireless device-to-device communication, comprising:

• establishing, by an audio output device, a first connection with a first audio source via a first wireless interface that communicates using a short-range device-to-device communication protocol on a first frequency band;
• negotiating, by the audio output device, that frequency-shifted communication is available for use with the first audio source;
• determining, by the audio output device, that the frequency-shifted communication is to be used for communication with the first audio source at least partially based on negotiating that the frequency-shifted communication is available for use with the first audio source;
• and
• performing, by the audio output device, frequency-shifted communication with the first audio source such that the audio output device receives a first audio stream from the first audio source using frequency-shifted communications outside of the first frequency band.
