Mbps vs MB/s — The Crucial Difference
Bandwidth Requirements

Nach Nutzung

E-Mail/Surfen: 1-5 Mbit/s. Streaming HD: 5-10/Stream. 4K: 25. Videocall: 3-5. Gaming: 5-10 (Latenz wichtiger). 4-Personen-Haushalt: 50-100 Mbit/s Minimum.

Glasfaser

Deutsche Glasfaser bietet hervorragendes Preis-Leistung: 300 Mbit/s fuer 40-50 €/Monat. Wi-Fi ist oft der Flaschenhals, nicht die Leitung. Wi-Fi 6 Router oder Mesh fuer grosse Wohnungen.

⚡ 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The "you only need 25 Mbps" claim from the FCC (2015 broadband definition) is woefully outdated.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.
