First announced at Ignite in November, ultrasound proximity join will be generally available in July 2024. Ultrasound proximity join is an alternative to Bluetooth that limits the range to join for the physical room, making it easier and faster to select the correct room from the pre-join screen. The user's companion device detects ultrasound beacons emitted only within the physical Teams Room. The ultrasound proximity provides a more accurate list of nearby Teams Room options on the pre-join meeting screen, making it easier for a user to know which Teams Room to add to their meeting.
