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 number of participants you are expecting.

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

General tips at larger events
