## RF Path Description
RF Path provides propagation loss calculations for radio frequencies (RF) between 20 MHz and 20 GHz using either the Irregular Terrain model, Okumura-Hata model, COST-231 Hata Extension model, or the COST-231 Walfish-Ikegami model. The calculations are based on both electromagnetic theory and the statistical analysis of terrain characteristics to calculate the degradation of the RF wave as a function of distance and the variability of the RF wave with respect to time and space.

The Irregular Terrain Model has two different prediction models. One is the Area Prediction mode which calculates propagation losses over an area where the exact terrain parameters are not known, but approximated using terrain roughness, environmental parameters and statistical parameters. 

The second is a point-to-point mode where specific latitude/longitude pair values are entered for both transmitter and receiver. Environmental parameters and statistical parameters are also used in this prediction mode.

The results may be saved to iCloud, emailed, or posted to Facebook or Twitter. The results are in CSV format.

In the Area Prediction mode a table along with a graph shows the path loss over the distance entered into the settings. The graph is viewed by rotating the device once the results table is shown.

In the Point-To-Point Prediction mode a table along with a graph shows the path loss and elevation profile of the RF path.

## RF Path Reviews in United States

### ***-- "Great except area notes"
Everything on point to point is great and straightforward. I can’t get the area model to work even after selecting help and some of helps instructions make no sense as the input is not available. I think something is wrong.
-- beilliams9968, 2024-10-28

### **--- "Broken."
Just purchased. It crashes every time I try to calculate. What a shame.
-- iEatbrains, 2020-07-26

### ***** "Provides the propagation loss calculation I need"
The app provides the RF path loss for me to enter into my analysis between a transmitter and receiver. I especially like the fact that the propagation calculations take into account near earth effects since I work with systems that are placed on the ground. It’s also great that the loss calculations are not based on free space loss. It would be nice to be able to save the coordinates for different paths that I work.
-- DWolst, 2019-08-03

### ****- "Great Propagation Estimation Tool"
I have worked with RF systems for more than 20 years. It’s great to have an app I can use to make propagation calculations that not only takes into account the terrain between the transmitter and receiver but also allows me to set the ground parameters based on the area of the world I am working. Only 4 stars because the results graph is sometimes too busy.
