An ordinary Teams Voice call requires around 100 Kbps for a two-way call, both upstream and downstream. However, to ensure best quality, reserve an additional 100 Kbps on each side, bringing the total requirement to about 200 Kbps per call. Calculate the total bandwidth requirement for Teams Voice by multiplying the bandwidth per call by the expected number of concurrent calls.
For instance, if 50 concurrent calls are expected:
50 calls * 200 Kbps/call = 10,000 Kbps, or 10 Mbps.
Thus, 10 Mbps would be the minimum bandwidth requirement to support 50 simultaneous Teams Voice calls.
Calculating Bandwidth for Microsoft Teams Video
Video calls on Teams require more bandwidth than voice calls. A low-quality video call (360p) requires around 500 Kbps, a standard-quality call (480p) requires approximately 1 Mbps, while a high-quality video call (1080p) needs about 2 Mbps. Again, this is both upstream and downstream.
To calculate the bandwidth required for Teams Video, determine the video quality preference and then estimate the number of concurrent video calls.
For example, if you anticipate 20 concurrent high-quality video calls, the bandwidth calculation would be:
20 calls * 2,000 Kbps/call = 40,000 Kbps, or 40 Mbps.
Calculating Bandwidth for Microsoft Teams Meetings
Teams meetings involve multiple participants and can include both video and voice calls. Each participant’s bandwidth contributes to the total bandwidth requirement. For instance, if a meeting incorporates video calls and there are 10 participants, the bandwidth required would be:
10 participants * 2Mb per participant = 20 Mbps (assuming high-quality video)
However, understand that not all participants might be speaking or displaying video at the same time. Teams meetings use intelligent algorithms that only allocate bandwidth to the five most active speakers.
Calculating Bandwidth for Microsoft Teams Live Events
Live Events reserve bandwidth based on the profile used, bitrate of the video, and number of viewers. A single 1080p video feed can require anywhere from 2 to 6 Mbps.
For instance, if you are hosting a Live Event with a single high-quality 1080p feed and have 100 viewers, the bandwidth calculation would be:
100 viewers * 6 Mbps/viewer = 600 Mbps.
Keep in mind, though, this is downstream bandwidth from the Teams service to the viewers, as the Live Event is typically broadcast out and doesn’t require significant upstream bandwidth.
In conclusion, grasping these bandwidth calculations is critical when managing Microsoft Teams. They help in networking planning and assessing whether the existing network can handle the expected Teams traffic, ensuring seamless communication and collaboration. Further, it is essential in mitigating potential bandwidth issues, providing a better Teams experience for all users.
