How It Works

An unlimited number of in-range Auracast receivers will be able to join an Auracast broadcast from a nearby Auracast transmitter.


Step 1

An Auracast transmitter begins an Auracast broadcast that includes advertisements, which provide Auracast assistants with information about the broadcast (e.g. name, content, codec configuration, etc.), as well as one or more audio streams (e.g. left and right stereo audio streams).


Step 2

Auracast assistants scan for Auracast advertisements and provide a user interface (UI) to enable users to select an Auracast broadcast to join, similar to the UI commonly used to connect to Wi-Fi networks in public spaces.


Step 3

Once an Auracast broadcast is selected, the Auracast assistant provides the Auracast receiver (e.g. headphone, earbud, hearing aid, etc.) the information it needs to join the Auracast broadcast.
