You consume bandwidth whenever you need to access the internet in a video or audio call, but
compared with other similar products, the traffic consumption of our products is very low:
Audio Call: 5-10kbps.
Video Call: The bit rate changes according to resolution and frame rate. In very simplistic terms (without taking color depth into account, or example), if the resolution is 180 by 320 pixels, and the frame rate is 15 fps, then the bit rate is160 kbps. For a bit rate calculator, try this page.
