Bandwidth Requirements
Mitel One web application works with IPv4 and IPv6 networks. The application will connect to the user’s preferred Wi-Fi network if that network is available. If there are problems with your Wi-Fi network connectivity, a Trying to connect, or a Device offline. Functionality will be limited alert appears. When this occurs, you may be unable to log in to the application. If this issue persists, contact your IT administrator. The voice quality and the connectivity depends on the network strength.
The following table specifies the recommended bandwidth for a single Mitel One call.
| Network | Kbps | Codec |
|---|---|---|
| Wi-Fi | 220 | G.711 and Opus |
Following are the bandwidth requirements for using various features of Mitel One Meetings.
Upload Bandwidth (Send)
| No. of Participants | Audio | Video | Screen Share |
|---|---|---|---|
|
2 or more |
54 kbps |
1600 kbps |
1200 kbps |
Download Bandwidth (Receive)
| No. of Participants | Audio | Video | Screen Share |
|---|---|---|---|
|
2-16 |
54 kbps |
1600 + (( n-2) * 400) kbps |
1200 kbps |
|
Note: n is the number of participants in a meeting.

The upload and download bandwidth mentioned in the table are the maximum values obtained during testing. The actual values will vary depending on the following factors:
- The resolution of the camera used for the meeting.
- The type of camera used for the meeting.
- The user’s Internet speed.
- The actual bandwidth utilization of other activities during the meeting such as desktop sharing or screen sharing.
Bandwidth requirements depend on the number of participants in a meeting, and the features that are being used by the participants during the meeting (video, screen share, and so on.)
- For example, in a meeting involving 3 participants with only audio and video enabled, bandwidth usage for a single participant is as follows:
- Upload bandwidth: 54 kbps + 1600 kbps = 1654 kbps
- Download bandwidth: 54 kbps + (1600 + (3-2) * 400) kbps = 2054 kbps
- When calculating the bandwidth for any meeting involving more than 16 participants, you must keep the number of participants as 16 because you cannot have more than 16 video tiles in a meeting.
