Frequently Asked Questions
How much internet speed does my business need?
Add the bandwidth of each concurrent activity: per-user tasks scale with active users, while calls and streams use a fixed count. Then add about 30% overhead for the recommended link speed.
What is concurrency?
Concurrency is the share of users active at the same moment. A 70% concurrency on 100 users means about 70 are generating traffic simultaneously.
How much bandwidth for video calls?
A VoIP audio call needs around 0.1 Mbps, while an HD video conference needs roughly 3 Mbps per stream.
Upload vs download?
This tool estimates aggregate throughput. Video calls and backups are upload-heavy, so choose a symmetrical or high-upload link if your business relies on them.
Estimates use typical per-activity bandwidths and vary with codecs, resolution and provider overhead. Use the result as a starting point and validate against real usage.
