Dual Connectivity
Offering multiple interfaces in a single product. This feature allows the use of one product in a room that requires multiple connectivity options (audio and video conferencing).
Bridging
The ability to connect two calls from different interfaces simultaneously, making your video conferencing participants able to speak with your audio conferencing participants as well as yourself through your device.
Direction Finding
The ability to recognize the direction of the person speaking in the room.
Beamforming
The ability to steer the directionality of the device’s microphones. Beamforming improves noise and echo cancelling as well as the overall quality of the device’s pickup. This feature works in conjunction with direction finding.
