Network Optimization

Signal Strength Optimization

Signal Indicators

Signal Bars	Quality	Expected Speed
4-5 bars	Excellent	Full speed
2-3 bars	Good	75% speed
1 bar	Poor	25% speed

Signal Improvement Tips

Move closer to windows or outdoors
Avoid basements and enclosed areas
Stay away from interference sources
Try different parts of your location
Use Wi-Fi calling when available

Network Selection

Automatic vs Manual:

Automatic: Device chooses best network
Manual: You select specific carrier

To Change (iPhone):

Settings > Cellular > Network Selection

To Change (Android):

Advanced Speed Optimization

Advanced Users Only: These settings require technical knowledge. Proceed with caution.

Fast DNS Servers:

Cloudflare: 1.1.1.1, 1.0.0.1
Google: 8.8.8.8, 8.8.4.4
Quad9: 9.9.9.9, 149.112.112.112

To Change DNS (iPhone):
Settings > Wi-Fi > (i) > Configure DNS > Manual

To Change DNS (Android):
Settings > Network & Internet > Private DNS

APN Settings for Speed:

APN Type: Ensure "default,supl" is included
APN Protocol: IPv4/IPv6 (dual stack)
Bearer: LTE (for 4G) or NR (for 5G)
MTU Size: Try 1440 or 1500

Note: Contact your carrier for optimal APN settings specific to your plan.

Enable Carrier Aggregation:

Carrier Aggregation combines multiple frequency bands for higher speeds.

iPhone: Usually enabled automatically
Android: Settings > Mobile Networks > Advanced
Look for "Enhanced 4G LTE" or "VoLTE" options
Enable "LTE Carrier Aggregation" if available

What to Monitor

Download Speed: Most important for browsing
Upload Speed: Important for video calls
Ping/Latency: Critical for gaming
Jitter: Stability of connection
Packet Loss: Connection reliability

Tip: Test at different times and locations to get accurate averages.

Speed Test Best Practices

Do This

Close all other apps before testing
Test multiple times and average results
Test at different times of day
Test from different locations
Use multiple speed test services
Record signal strength during tests

Avoid This

Testing with other apps running
Testing only once and assuming that's normal
Testing only during peak hours
Testing from poor signal areas only
Comparing different carriers unfairly
Ignoring network congestion factors
