Network requirements

This page specifies what is required to run Mentimeter.

Bandwidth requirements

Mentimeter's platform is designed for a large number of participants. If any problems occur it is usually related to local network restrictions at the venue of the presentation. Following table shows minimum bandwidth requirements for the amount of participants you are expecting.

Note: For larger crowds it is strongly recommended that you also check with the local IT technician that the WiFi can support the expected amount of participants at the same time.

Participant Amount Recommended bandwidth
10 0.5 Mbit/s
50 2.5 Mbit/s
100 5 Mbit/s
500 15 Mbit/s
1000 30 Mbit/s

You can check the bandbwidth of your location using SpeedTest or a similar service.
