If there are many devices connected to the same Wi-Fi, you will experience packet loss and pixellated images. The video will never be better than the network it is connected to. Signal strength, QoS and number of devices often play a big role. Also, it is often recommended to turn down the bandwidth and the FPS in order to get better experiences.
Often, internet providers have an asymmetrical relationship between the incoming bandwidth and the outgoing bandwidth e. Incoming bandwidth is the bandwidth consumed when you receive a stream from somewhere on the internet, while outgoing bandwidth is the bandwidth consumed when you transmit a stream to someone on the internet. If you just do local streaming, on the same WiFi network, then bandwidth should generally not be an issue if the WiFi infrastructure is of high enough quality.
Low quality WiFi equipment can cause severe packet loss. Minimum requirement for video is p. Example scenario: Cisco Webex Video Platform meetings scales the video quality down to lowest common denominator of users who are at or above the minimum video quality p.
This means that video quality downgrades for the rest of the Webex attendees based on the slowest connection above the minimum video quality. For example, if a single participant has joined from an iPhone 4 which is only capable of receiving at 90p, that user will not receive video and only that user receives the 'Low-bandwidth warning' from TelePresence endpoints who are the active speaker in the meeting.
The next highest user above the minimum video quality p sets the lowest common denominator for all Webex participants to receive from TelePresence. For the best video experience in Cisco Webex Video Platform meetings, each screen must have at least 2.
Warnings and errors are received if your available bandwidth falls below the minimum required for Cisco Webex Video Platform 1. To view the warning messages, see: Low Bandwidth Warnings. After you correct the problem with your network connection, video will resume automatically.
