RF Propagation Analyzer
Analyze RF coverage, model propagation, and solve radio link problems
What You Can Do
Model how radio waves propagate through environments using empirical and theoretical approaches. Calculate link budgets, predict signal strength at specific locations, and diagnose coverage gaps using measurement data. Claude analyzes your propagation models, suggests optimizations, and interprets measurement results in the context of standard RF theory.
Features
Compute transmitter power, antenna gains, path loss, and receiver sensitivity to determine signal margins and coverage limits.
Choose appropriate models (Friis, log-distance, Okumura-Hata, ITM, or empirical) based on frequency, environment, and distance.
Calculate expected signal attenuation using theoretical formulas and compare against field measurements to validate or adjust models.
Generate signal strength estimates across a service area, identify dead zones, and recommend transmitter placement or power adjustments.
Parse field survey data and correlate real measurements with model predictions to calibrate models for your specific environment.
Calculate acceptable fade margins for link reliability, account for weather effects, and compute system availability percentages.
Analyze antenna placement, gain configurations, and directional patterns to improve link performance and coverage efficiency.
Example Output
Link Budget Analysis
Scenario: 2.4 GHz WiFi at 100m indoor office
- Transmitter power: 20 dBm
- Path loss (log-distance, n=3.5): 87 dB
- Antenna gain (TX): 5 dBi, (RX): 2 dBi
- Received power: 20 + 5 + 2 - 87 = -60 dBm
- Receiver sensitivity: -80 dBm
- Link margin: 20 dB (healthy)
Coverage Recommendation
Your measurement shows -85 dBm at 200m, but Okumura-Hata predicts -75 dBm. The difference suggests attenuation from building materials. Recommend: relocate transmitter 30m closer or add 6 dBi gain antenna.
Fade Margin Calculation
For 99.9% availability over 10 km LOS microwave link with 3mm/hr rain, you need 22 dB fade margin but have 18 dB link margin. Action: increase transmit power by 4 dB or boost RX antenna gain.
