Overview
- The capability is available to all Google Workspace customers and Workspace Individual subscribers who meet app version requirements.
- Room hardware emits an inaudible ultrasonic signal that nearby Android and iOS devices detect via their microphones to surface the “Use Companion mode” option in the green room.
- Tapping Companion mode pairs the personal device with the room system without taking primary control and automatically checks the user into the correct room.
- Proximity detection is enabled by default for conference rooms, with administrators able to switch it on or off per room.
- Minimum builds include Google Meet 336.0 on Android and iOS and Gmail 2025.12.01 on Android or 6.0.251201 on iOS.
