Mbps vs MB/s — The Crucial Difference
Bandwidth Requirements

Por Uso

Email/navegação: 1-5 Mbps. Streaming HD: 5-10 por fluxo. 4K: 25. Videochamada: 3-5. Gaming: 5-10 (latência importa mais). Família de 4 com todos online: 50-100 Mbps mínimo. No Brasil, a fibra FTTH está disponível na maioria das cidades médias e grandes.

Fibra no Brasil

A fibra brasileira oferece excelente custo-benefício: 300 Mbps por R$80-120/mês. Muito mais acessível que nos EUA. O Wi-Fi é frequentemente o gargalo, não a fibra. Roteador Wi-Fi 6 ou mesh para casas grandes resolve.

⚡ CalcWolf Insight

The "you only need 25 Mbps" claim from the FCC (2015 broadband definition) is woefully outdated. A single 4K Netflix stream uses 25 Mbps. With remote work, video calls, smart home devices, and multiple family members, 100 Mbps should be the minimum standard in 2026. Many ISPs offer 300-500 Mbps for $50-70/month — worth it for the headroom.
