Short definition
Bandwidth refers to the maximum amount of data that can be transmitted over a network connection per unit of time – a critical factor for digital and hybrid conferences.
Detailed explanation
Modern events don't run smoothly without sufficient bandwidth. Livestreaming, video conferencing links, remote interpreting, app-based voting systems – all of this consumes bandwidth. And when several of these applications run at once, the available capacity quickly becomes a bottleneck.
Bandwidth is measured in megabits per second (Mbps) or gigabits per second (Gbps). For a professional conference with simultaneous interpreting and a livestream, at least 50–100 Mbps symmetrical (upload and download) should be planned for – often significantly more, depending on the number of streams and participants. On top of that, venues often have worse connections than expected, which makes checking the on-site network infrastructure in advance essential.
For critical events, a backup connection is always recommended – for example via LTE or a second DSL line from a different provider. Bandwidth bottlenecks are among the most common technical problems at hybrid events.
Relevance in this subject area
Bandwidth is the invisible infrastructure behind every digital conference. It determines image quality, transmission stability, and the reliability of remote interpreting solutions.
Practical example
At a hybrid congress with 200 people on-site and 800 viewers on the livestream, a bandwidth test is run in advance. The result: the venue only offers 20 Mbps – an LTE bonding router is planned as a backup.
