Bandwidth requirements for Biba calls (audio, video and screen share)

Biba offers HD VoIP audio, HD video, screen share and remote control services. The following information is intended to help you determine network bandwidth requirements (both download and upload) based on the combination of services that you choose to us on any given meeting.


  • 1-1 call
    • 54 kbps up and down
  • Large call (> 50 attendees)
    • 54 kbps up and 96 kbps down
  • Note:
    • There may be times when you may have drops in the network connectivity - Biba has the ability to buffer the audio and when the bandwidth improves we use our technology to "play back" what was said at a increased rate until we catch up.

Screen Sharing:

  • presenting
    • 600 kbps up
  • viewing
    • 600 kbps down
    • Note: down bandwidth will adapt down to 200 kbps as needed based on network conditions


  • 1-1 call
    • 650 kbps up and down
    • for HD mode: 1400 kbps up and down
  • 3-4 people
    • 450 kbps up and (N-1)*400 kbps down
  • 5-16 people
    • 184 kbps up and (N-1)*134 kbps down
    • Note: up and down bandwidth will adapt as needed based on network conditions
  • Video requires more bandwidth than other services so we do a few things to help manage the demand:
    • Biba performs some magic to endeavor to deliver you the highest quality video for your available bandwidth and your video tile size (i.e. when you scale down your video tiles, we will scale down the resolution so you get a high quality image without all the bandwidth drain).
    • Remember you can pause a video tile for another attendee you might not need to view to help reduce some of the download bandwidth.
    • If we detect bad network conditions, we will automatically pause your video (to preserve audio) and let you know that your video was paused. It will reconnect again once the conditions are more favorable.

If you are having issues with the quality of your Biba meetings, we recommend:

  • Close other applications that use the internet, especially those playing music or video.
  • Cancel any file transfers in progress including background syncs performed by or dropbox and other file share services.
  • Pause or delay background application updates.
  • If you are connecting via wifi, you might want to try connecting via ethernet as your wifi access points may be saturated.
  • If you are connected directly to the internet, you might want to check with your IT administrator as you may have your download or upload speed capped.

If this does not resolve your problem, you may need to increase your bandwidth. Contact your IT admin if you need more information regarding your download and upload speeds.
