Calculadora de largura de banda de rede.
Calcule a largura de banda de download e upload de que um escritório precisa conforme utilizadores e aplicações, com margem e ligação recomendada.
- Recommended download
- 300 Mbps
- Recommended upload
- 200 Mbps
- Symmetric link (fibre, dedicated)
- 300 Mbps
- Headroom factor applied
- × 1.95
Demand at peak
| Application | Active users | Down | Up |
|---|---|---|---|
| Web browsing and SaaS apps | 36 | 54 Mbps | 10.8 Mbps |
| E-mail and chat | 48 | 9.6 Mbps | 4.8 Mbps |
| Video meeting 1080p | 12 | 36 Mbps | 45.6 Mbps |
| VoIP call G.711 (Ethernet, 20 ms) | 6 | 523.2 kbps | 523.2 kbps |
| Cloud backup and file sync | 6 | 30 Mbps | 30 Mbps |
| Total before headroom | 130.12 Mbps | 91.72 Mbps |
- Per-user rates are typical published recommendations (video meeting, streaming and VoIP vendors); replace them with your vendor’s figures.
- Consumer links are often asymmetric: video meetings and cloud backup usually make upload the limit.
- For voice and video, quality also depends on latency, jitter and QoS, not only on bandwidth.

Per-user rates are typical published recommendations; replace them with your vendor’s figures. Latency, jitter and QoS are not modelled. Everything is calculated in your browser; nothing is sent or probed on the network.
Active users × per-user rate, summed per direction, then multiplied by protocol overhead and growth and divided by the maximum utilisation of the link.
60 users browsing, meeting in 1080p, calling and syncing files need about 254 Mbps down and 179 Mbps up with headroom: a 300 Mbps symmetric link.
