What does the Bandwidth Capacity Planner do?

This tool estimates how much internet bandwidth a team or site may need based on user activity. It combines light browsing, video meetings, heavy downloads, DevOps traffic, and VoIP profiles with a concurrency factor to produce a practical link recommendation.

Why bandwidth planning matters

Buying only by advertised speed can lead to poor performance or unnecessary cost. Real capacity planning considers simultaneous users, traffic type, growth buffer, upload needs, and whether business-critical apps are sensitive to latency or packet loss.

Who benefits from it?

IT managers, network engineers, MSPs, office administrators, call center planners, DevOps teams, and small business owners can use it before ordering or upgrading an ISP circuit.

FAQ

What is concurrency factor? It estimates the percentage of users actively consuming bandwidth at the same time.

Is more bandwidth always better? Not always. Latency, jitter, WiFi quality, routing, and QoS can matter as much as raw Mbps.

Should I include a growth buffer? Yes. A 20% or higher buffer helps absorb user growth, software updates, and traffic spikes.
