What's the difference between Mbps and MBps?

Mbps (megabits per second) is used for internet speeds, while MBps (megabytes per second) is used for file sizes. 1 byte = 8 bits, so 100 Mbps = 12.5 MBps download speed.

How much speed do I need for 4K streaming?

Netflix recommends 25 Mbps for 4K streaming, but real-world usage can be 15-35 Mbps depending on compression. For multiple 4K streams, plan for 50-100 Mbps.

Why is my actual speed slower than advertised?

Internet speeds are 'up to' advertised rates. Real speeds are affected by network congestion, Wi-Fi signal strength, device capabilities, and server limitations.

Bandwidth Formulas & Real-World Examples

Essential Formulas

Download Time:
Time = (File Size × 8) ÷ Internet Speed

Where:
File Size in bits (×8 from bytes)
Internet Speed in bits per second
Time in seconds

Data Usage:
Monthly Data = (Speed × Hours × 3600 × 30) ÷ (8 × 1024 × 1024)

Common Examples

100 Mbps Internet:
1GB file = 1.4 minutes
10GB file = 14 minutes

4K Streaming:
Single stream = 25 Mbps
Data per hour = 11.25 GB

Family of 4:
Recommended speed = 200-400 Mbps
Monthly data = 1-2 TB

Remote Work:
Video calls = 5-8 Mbps
Large files = 50-100 Mbps

Bandwidth Planning Tips:

Plan for Peak Usage: Calculate based on simultaneous usage, not individual devices. Consider Upload Speeds: Many plans have slower uploads - important for video calls and backups. Data Caps Matter: 4K streaming can use 1TB in just 90 hours. Future-Proofing: Internet usage typically doubles every 2-3 years.
