How to fill out itu-r p528 propagation curves

1. To fill out ITU-R P.528 propagation curves, follow these steps:
2. Start by gathering the necessary data, including the frequency range, transmitter power, transmitting and receiving antenna heights, distance between the transmitter and receiver, terrain data, and climate data.
3. Plot the terrain profile between the transmitter and receiver, using topographic maps or digital elevation models.
4. Determine the type of climate conditions, such as continental, maritime, or tropical, and obtain the corresponding climate data like the median monthly surface refractivity and the surface temperature lapse rate.
5. Calculate the Effective Earth Radius Factor (Fresnel-Kirchhoff factor) based on the frequency and distance between the transmitter and receiver.
6. Use the Longley-Rice method or other suitable propagation model to calculate the path loss or field strength for different propagation distances and antenna heights.
7. Compile the calculated data into a table or graph, representing the propagation curves. Include the distance, antenna height, path loss or field strength, and other relevant parameters.
8. Validate the generated propagation curves using field measurements or comparisons with existing measurements.
9. Document the entire process and ensure clear and concise communication of the results.
10. Review and update the propagation curves as new data or measurement results become available.
11. Ensure adherence to the guidelines and recommendations specified in ITU-R P.528 throughout the entire process.
