Calculadora de Largura de Banda Online Grátis
Network bandwidth requirements for concurrent users and usage patterns
The Bandwidth Calculator estimates the total network bandwidth your infrastructure needs to support a given number of concurrent users across different activity types — video streaming, VoIP calls, web browsing, and file transfers. IT managers and network architects use it to size internet connections, plan capacity upgrades, and justify bandwidth purchases to stakeholders.
Frequently Asked Questions
Sobre Esta Calculadora
Underestimating bandwidth leads to congestion, sluggish video calls, and frustrated users. Overestimating means paying monthly for capacity you never use. Accurate bandwidth planning requires knowing not just how many users you have, but what they're doing simultaneously — streaming, calling, downloading, or browsing each have dramatically different bandwidth profiles.
This calculator models multiple user groups with different usage patterns and aggregates them into a total bandwidth requirement, automatically adding a configurable headroom percentage for traffic bursts and protocol overhead. The calculation is based on industry-standard average bandwidth figures for each activity type.
Network engineers and office managers use this tool when evaluating ISP contracts, designing remote office connectivity, or documenting requirements for IT procurement. It pairs naturally with the Subnet Calculator when planning the IP address space for the same network segment.
A Calculadora de Largura de Banda estima o consumo de rede da sua infraestrutura para um certo número de usuários e usos.
Exemplo Resolvido
Sizing office internet for 50 simultaneous users
Entradas:
- 30 users: general web browsing (avg 2 Mbps each)
- 15 users: video conferencing HD (avg 3.5 Mbps each)
- 5 users: large file uploads (avg 10 Mbps each)
Passo a Passo:
- Web browsing: 30 × 2 Mbps = 60 Mbps
- Video conferencing: 15 × 3.5 Mbps = 52.5 Mbps
- File uploads: 5 × 10 Mbps = 50 Mbps
- Raw total: 60 + 52.5 + 50 = 162.5 Mbps
- Add 20% headroom for bursts and overhead: 162.5 × 1.20 = 195 Mbps
