Frequently Asked Questions
What's the difference between Mbps and MB/s?
Mbps (megabits per second) measures internet speed, while MB/s (megabytes per second) measures file transfer speed. To convert: 1 MB/s = 8 Mbps. So 100 Mbps internet = 12.5 MB/s download speed in ideal conditions.
How much bandwidth do I need for streaming?
Netflix 4K: 25 Mbps, HD: 5 Mbps. YouTube 4K: 20 Mbps, 1080p: 5 Mbps. Zoom HD video: 3.8 Mbps. Gaming: 3-6 Mbps (low latency more important). Multiple users: Add requirements together plus 25% overhead.
Why is my actual speed lower than advertised?
ISPs advertise "up to" speeds under ideal conditions. Real-world factors include: network congestion (70-90% typical), WiFi limitations (50% loss possible), protocol overhead (10-20%), and distance from router. Expect 70-80% of advertised speeds on average.
How do I calculate download time?
Download time = File size ÷ Download speed. Convert both to same units first. Example: 10 GB file at 100 Mbps = 10,240 MB ÷ 12.5 MB/s = 819 seconds (13.7 minutes) under ideal conditions. Add 20-30% for real-world overhead.
What bandwidth is needed for a business?
Per employee: Basic (email/web): 1-2 Mbps, Standard (cloud apps): 5-10 Mbps, Heavy (video/large files): 25+ Mbps. Add 50% overhead for peak usage. 20-person office with standard usage needs about 200-300 Mbps symmetrical connection.
How does bandwidth relate to data caps?
Bandwidth (speed) × Time = Data usage. Example: Streaming at 25 Mbps for 1 hour uses 11.25 GB. Monthly 1 TB cap allows ~89 hours of 4K streaming. Monitor usage carefully with video streaming, cloud backups, and large downloads.
