Avantree Auracast transmitters can support up to 300 ft / 100 m in open space.
Actual range depends on walls, interference, receiver performance, and where the transmitter is placed.
Auracast can be used as a public broadcast or a private/encrypted broadcast, depending on the transmitter and setup.
Some Avantree models will support private or encrypted mode through firmware updates.
Auracast is mainly for audio streaming, not calls.
You can listen through your hearing aids or headphones, and use your computer’s built-in microphone for speaking.
For full call support with microphone audio, use an LE Audio transmitter such as C82 LEA.
LE Audio is typically for one-to-one connections and can support calls and microphone use.
Auracast is for one-to-many audio broadcasting, so multiple listeners can join the same audio source.
