Conference room video calls stutter while the uplink is supposedly fine.
A Teams or Meet call in a big room with a 1080p camera takes about 2 to 4 Mbit symmetric per session. The problem is rarely the total uplink, it is jitter, Wi-Fi packet loss or an AP that cannot handle the room. A full office of 30 people in calls at once is a design question, not an uplink question.
Try this first
- 1Check uplink from one workstation: 25 Mbit symmetric is enough for 5 concurrent HD calls if the Wi-Fi is healthy.
- 2Cable the room AV (Logitech Rally, Poly Studio, Cisco Bar), do not put it on Wi-Fi. That alone removes 80 percent of the issues.
- 3Set QoS tags on switch and firewall for Teams (UDP 3478-3481) and Meet, otherwise the call competes with OneDrive sync.
- 4Count peak concurrent calls: 30 people in 30 one-on-one calls is not a meeting, it is an uplink party. Plan capacity for that peak.
- 5Measure jitter and packet loss during a real workday, not at 8 in the morning, that is where the truth is.
When to bring us in
Lots of client meetings on video, recordings that get reused, or hybrid sessions with external speakers: a measured room design plus a dedicated AP per room is worth it.

- Wi-Fi drops randomly across the officeFirst rule out whether it is the access points or the internet connection itself. Different fix.
- One room or corner has no or bad Wi-FiNot always "add another AP"; often one is poorly positioned, or there is a metal wall in the way.
- Internet is suddenly slow for everyoneThree suspects: your provider, a colleague soaking the line, or a backup or update kicking in unexpectedly.
