Although Team Free provides a dual-stream interactive mode, it actually requires a certain bandwidth to use dual-stream. Generally, it can be used under the network conditions of at least 5M uplink and 10M downlink (at this time there is no other bandwidth consumption). When the network conditions are not good, it will prompt the network quality problem, and the system will automatically adjust the video picture quality, but for a better experience, the user can close a video stream and use a single stream for communication and collaboration. Users can turn off the video and go directly to the audio. In addition, when the WIFI signal is not very good, it is recommended to use a wired network to ensure the experience.
