Many network factors affect the performance of the Acrobat Connect Professional application for attendees, including the bandwidth setting for the meeting room, the connection speed setting for each individual attendee, and the type of content being shared and activities being performed in the meeting.

For example, higher bandwidth is required to share a recorded video than to share a text document, and higher bandwidth is required to broadcast live video than to send chat messages.

Optimize Room Bandwidth

The meeting host can specify the bandwidth setting at which the meeting is broadcast. Options are Modem, DSL/Cable, and LAN. You should match the room bandwidth to the connection speed available to attendees. For example, only use LAN if all your attendees have access to LAN. If attendees are on a variety of connection speeds, it is best to choose the slowest speed that attendees are using. If a number of attendees are using Modem connection, set the room bandwidth to Modem.

Attendee Connection Speed

Each attendee can choose My Connection Speed from the Meeting menu and select Modem, DSL/Cable, or LAN. Attendees should choose the connection speed that matches their Internet connection type. If attendees experience latency in receiving an audio or video broadcast, they should reduce their connection speed setting.

The following general guidelines are recommended for room bandwidth settings. Actual speeds may 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/Cable: 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.
