Real-Time Audio-Video bandwidth varies according to the webcam's image resolution and frame rate, and the image and audio data being captured.

The sample tests shown in 1 measure the bandwidth that Real-Time Audio-Video uses in a View environment with standard webcam and audio input devices. The tests measure the bandwidth to send both video and audio data from Horizon Client to Horizon Agent. The total bandwidth that is required to run a desktop session from Horizon Client might be higher than these numbers. In these tests, the webcam captures images at 15 frames per second for each image resolution.
