Set meeting room bandwidth

The host sets meeting room bandwidth to determine the speed (kilobits/second) at which data from the meeting is sent to attendees. The host should choose a room bandwidth that matches the connection speed used by attendees. If attendees are using a variety of connection speeds, choose the lowest speed that attendees may be using. For example, if some attendees are using modems, choose Modem for room bandwidth to ensure that all attendees have a good connection and client computers are not overloaded.

The following general guidelines are recommended for room bandwidth settings. Actual speeds can vary according with each network environment:

  • Modem: One presenter can generate around 26 kbits/second of data. Attendees need around 29 kbits/second for a good connection. Having more than one presenter with the Modem setting is not recommended. Screen sharing with the Modem setting is not recommended.

  • DSL: One presenter can generate around 125 kbits/second of data. Attendees need around 128 kbits/second for a good connection. If screen sharing is used, attendees should have 200 kbits/second.

  • LAN: One presenter can generate around 250 kbits/second of data. Attendees need around 255 kbits/second. If screen sharing is used, attendees should have 400 kbits/second.

  1. In a meeting room, select Meeting > Room Performance And Appearance > Optimize Room Bandwidth.
  2. Select Modem, DSL/Cable, or LAN.
