- For VoIP events use a headset/mic, not the internal PC microphone or mic built into a web camera.
Users should run the Connection Wizard to make sure they have the latest version of Flash and install the Connect Add-in if possible - also note their Connection speed for the next step, go to the Adobe Testing Site.
Many folks sit on a LAN, but because of network traffic, length of cable, wi-fi (not recommended for meetings) or other factors - only get DSL or Modem speed throughput to their client.
- Meeting users should go to the Meeting drop-down menu and under "Manage My Settings" select "My Connection Speed" and select Modem/DSL/LAN depending on what the Connection wizard told them.
All users should run the audio setup wizard ahead of the meeting to test their microphone and speakers, test location silence settings and reduce echo. Go to the "advanced settings" tab at the end and un-check "enhanced audio".
I've seen lots of cases where headsets were not used and participants essentially transmit the audio from the meeting out their speakers back through their microphone creating an echo for other participants. Usually the built-in echo cancellation catches this, but not always which is why I always recommend a headset/mic combo.
- You should not run other applications in the background during meetings, particularly web applications (email, chat, etc.). These compete for CPU and client bandwidth to the internet. In some cases, people will be running applications that are using the camera or microphone driver already which restricts Connect from using the same driver in the meeting room.
- Set expectations for the "push to talk" mechanism such that you start talking a moment after the button has been pushed as opposed to starting to talk as the button is being pushed. I've seen many cases where the first part of a person's sentence is cut off because they are talking as the button is still being engaged.
- As it relates to 6, consider push to talk vs. having everyone lock the talk button down. First, whether you're talking or not, if the lock button is down, your're transmitting audio - no reason to clog up the pipe with bits of silence.
Host/Meeting Organizer Tips
- The Meeting Host, under the "Meeting" drop down, should optimize the meeting room bandwidth depending on the lowest connection speed of the participants (see below).
- Assuming all users completed set 3, the meeting host should consider setting room bandwidth at the speed of the lowest connection, especially if several participants show up in the connection status window (see below).
- If bandwidth is the potential issue, consider not using multiple web cams - or pausing them when they are not physically speaking.
- If multiple speakers are involved, make sure the "multiple speaker" option is selected in the audio option in the room.
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 to 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.
View attendee connection status
A group of bars, like the bars indicating signal strength on a mobile device, can appear next to an attendee name in the Attendee List pod to indicate an attendee's connection status. (This option is off by default.) When the attendee's connection falls below the current meeting room bandwidth, the number of bars in the icon decreases. Hosts can configure the network connection status indicators to be on or off any time during a meeting.
The network connection status is shown for all attendees that have a bandwidth set lower than the room bandwidth you selected. For example, if the room bandwidth is set to DSL/Cable, connection status is shown for attendees with a connection speed set to Modem. (Attendees can set their connection speed by clicking Meeting > Manage My Settings > My Connection Speed.)
To enable this feature - 1) in the menu bar, select Meeting > Room Performance And Appearance > Optimize Room Bandwidth 2) Select DSL/Cable or LAN 3) Click the Pod Options button in the lower-right corner of the Attendee List pod 4) Select Show Connection Status from the pop-up menu.
