Download Speed vs Upload Speed
Most activities focus on download speed, but these require upload speed:
Upload-Heavy Activities:
- Video conferencing: 3-10 Mbps upload
- Live streaming (Twitch): 10-20 Mbps upload
- Cloud backups: 20+ Mbps upload (Google Photos, Dropbox)
- Uploading YouTube videos: 50+ Mbps upload (4K video files)
- Remote desktop/VPN: 5-15 Mbps upload
Cable internet upload speeds:
- 100 Mbps plan: Usually 5-10 Mbps upload
- 500 Mbps plan: Usually 20-35 Mbps upload
- 1 Gbps plan: Usually 35-50 Mbps upload
Fiber internet upload speeds:
- Symmetrical: Same upload as download (1 Gbps / 1 Gbps)
If you need high upload speeds: Choose fiber over cable.
How to Calculate Your Exact Needs
Step 1: List All Simultaneous Activities
During peak usage (evenings, weekends), what happens at the same time?
Example peak usage (6 PM on weekday):
- Parent 1: Zoom call (3.8 Mbps)
- Parent 2: Netflix 4K (25 Mbps)
- Kid 1: Gaming + Discord (10 Mbps)
- Kid 2: YouTube HD (5 Mbps)
- Smart home: Cameras, devices (10 Mbps)
Total: 53.8 Mbps → Recommended: 100 Mbps plan (allows overhead)
Step 2: Add 25-50% Overhead
Internet speeds fluctuate. Add buffer:
- 25% overhead: Reliable connection (fiber)
- 50% overhead: Variable connection (cable, DSL)
Example: 54 Mbps needed × 1.5 (50% overhead) = 81 Mbps → Choose 100 Mbps plan
Step 3: Test Your Current Speed
Visit InternetSpeedTest.net to test:
- If current speed > your calculated needs: You're overpaying → downgrade
- If current speed < your calculated needs: Buffering, lag → upgrade
Common Bandwidth Mistakes
❌ Mistake 1: Buying Too Much Speed
Problem: Paying for 1 Gbps when household needs 200 Mbps.
Cost: $30-50/month wasted (~$360-600/year)
Solution: Calculate actual needs, downgrade if not gaming or WFH.
❌ Mistake 2: Ignoring Upload Speed
Problem: 500 Mbps plan with only 10 Mbps upload → video calls freeze.
Solution: Check both download and upload speeds before signing up. Fiber provides symmetrical speeds.
❌ Mistake 3: Confusing Mbps with MBps
- Mbps (megabits per second) = internet speed advertised by ISPs
- MBps (megabytes per second) = download speed in apps
Conversion: 100 Mbps = 12.5 MBps (divide by 8)
Example:
- 1 Gbps internet = 125 MBps download speed in Steam
- 50 GB game download = ~7 minutes on 1 Gbps, ~70 minutes on 100 Mbps
❌ Mistake 4: Not Considering Number of Devices
Each device shares total bandwidth.
Example: 100 Mbps connection with 5 devices streaming simultaneously:
- 100 Mbps ÷ 5 = 20 Mbps per device (enough for HD, not 4K)
Solution: Higher speed plans for multi-device households.
