![]() Video conferencing bandwidth requirements are usually equal in both directions. Most residential connections provide much higher download speed than uploads. ![]() ![]() The available bandwidth is shared between clients, and speeds may be much lower at peak times. Notes: Most residential internet connections quote speeds of "up to" X Mbps. Audio calling and screen sharing uses up to ~130 kbps. Group video requires about 1Mbps, HD group video uses about 2 Mbps. Microsoft Teams uses about 1.2 Mbps for HD video calling (720p), 1.5 Mbps for 1080p, 500 kbps for standard quality video (360p). You must take into account current demands and. A good place to start is to determine bandwidth demands for IP addresses, department and branch, as well as the overall organization. Skype requires about 1.2Mbps (up/down) for high-definition video, with a minimum requirement of about 0.5Mbps. Before moving any workloads to a cloud infrastructure, a comprehensive assessment of network capabilities and bandwidth requirements is in order. Bandwidth requirements for video conferencing vary depending on the software/platform you use, however the average seems to be about 2 Megabits/second both. Screen sharing and audio VoIP calling uses 60-100kbps. To work from home, you should have an internet download speed of at least 25 Mbps and upload speed of 3 Mbps. Below is a list of the most common programs with their respective bandwidth requirements: Zoom requires between 1 Mbps and 3 Mbps (up/down) for video streaming, depending on the quality, and whether it is 1:1 or group video. Below is the overhead introduced by each overhead item: RTP 4.8 kbps. Irrelevant of the codec used, the overhead introduced in the packet is fixed. Note that video conferencing has much higher upstream requirements than other applications. We shall refer to these packages collectively as overhead. Also, with residential internet connections, upstream (upload) bandwidth is usually much lower than downstream (download) bandwidth. Most broadband connections are able to easily accommodate single user video conferencing without any issues, however, keep in mind that multiple users at home may be using bandwidth-intensive applications including video conferencing, gaming, streaming online video content, downloading Windows updates, etc. Before you deploy for the first time or migrate to Office 365, you can use the information in these topics to estimate the bandwidth you need and then to test and verify that you have enough bandwidth to deploy or migrate to Office 365. With the increase in remote work and school activities, it is important to know the bandwidth requirements for various products so you can plan for a sufficient internet connectivity accordingly. This article contains links to information about network planning and testing, and migration to Office 365. Bandwidth requirements for video conferencing vary depending on the software/platform you use, however the average seems to be about 2 Megabits/second both down and upstream for high-definition video.
