Bandwidth Requirements by Use Case

Use CaseUsersRecommended Bandwidth
Home (basic browsing + streaming)1–425–100 Mbps
Small office (email + web)5–1550–150 Mbps
Medium office (video calls + cloud)15–50200–500 Mbps
Large office (all applications)50–200500 Mbps – 2 Gbps
Enterprise200+2 Gbps+ (dedicated lines)

What Affects Bandwidth Requirements?

Several factors influence how much bandwidth your network needs. The number of simultaneous users is the biggest factor — not all users are active at the same time, which is why we use a concurrency percentage. Application type matters enormously: 4K video streaming uses 25x more bandwidth than basic web browsing. Understanding your network throughput and actual bandwidth usage helps you choose the right router and ISP plan.

Frequently Asked Questions

Is 100 Mbps enough for an office of 20 people?

It depends on usage. For light use (email, web browsing), 100 Mbps may be sufficient. But if your team regularly uses video conferencing, cloud storage, or large file transfers, you should consider 200–500 Mbps for 20 users.

What is the difference between bandwidth and speed?

Bandwidth refers to the maximum data transfer capacity of a network connection, measured in Mbps or Gbps. Speed refers to how fast data actually transfers in practice, which is affected by latency, packet loss, and network congestion. Learn more about bandwidth in networking.
