What technology use for pair iPad and cisco room system:

Wi-Fi provides the underlying network transport after pairing is established but is not the pairing technology itself - Cisco Proximity handles the discovery and authorization layer.

Bluetooth is not supported as the pairing mechanism between an iPad and Cisco room systems; Cisco Proximity's ultrasound signaling is used instead.

Cisco Proximity uses an ultrasound pairing signal emitted by the room system to detect nearby mobile devices. Once paired, the iPad can share content, control the room system, and access call information without requiring manual network configuration, providing a seamless in-room collaboration experience.
