Radio Mobile * Free Radio Arranging Software

My radio app

Radio wave reproduction is a very complex method. It is impossible to precisely predict how waves will spread as well as what values we will evaluate at some certain point. Therefore we incorporate some mathematical models in order to approximate radio distribution and to calculate area strength values as outlined by predefined probability.

The propagation model, which is based on electromagnetic concept and on statistical evaluation of both landscape features and radio measurements, predicts the particular median attenuation of the radio stations signal as a objective of distance and the variation of the signal in time and in space. Distribution models define figure and formulas. With your model we can anticipate propagation in irrelavent distance from the transmitter.

Employing curves and statistical formulas manually is definitely a tough task. To be able to automate and quicken such calculations a lot of software tools were produced. Normally, radio arranging software packages are used by tv producers, mobile operators as well as radio frequency authorities. Because of complexity and small number of potential customers, the price of this kind of software package can be rather high. But there is a single exception to this guideline.

Radio Mobile is really a software tool for stereo propagation calculation. The article author has decided to publish it under the "freeware" license meaning the software is openly available on the web. This software is primarily dedicated to amateur r / c, however, it can be in addition used in other areas including broadcasting and expert mobile communications.

Calculations are based on the Longley-Rice reproduction model. This is a standard purpose radio reproduction model for wavelengths between 20 Megahertz and 20 Ghz. In order to use the software you additionally need terrain style data. This info is needed for calculations involving effective heights which are needed to perform distribution calculations. You can find a few terrain model info sources on the web. They provide free DTM (Digital Terrain Model) data that's enough to start working together with the Radio Mobile.

Radio Mobile supports several fancy features like possibility to use DTM in numerous formats (DTED, SRTM), also in many layers with different solution, possibility to add guide pictures in raster file format (BMP, JPEG, GIF, TIFF, PNG), possibility to determine interference between radio stations and lots of functions a customized view.

Basic means of use consists of coming into radio stations with all variables (if they are not joined yet) and calculations of the coverage. Here you have a lot of options to customize the calculation and consider. Results can be stored for later use. It is also possible to define calculation action for coarse calculations to save some time.

Regarding result display it is almost always not enough to display this on the gray size DTM. You would probably like to see this on some road. For this purpose you can use just about any map picture along with known coordinates. The software allows you to enter coordinates for each picture in order to display it correctly over the DTM.

A very beneficial function is the formula of interference involving radio stations. You outline protection ratio along with minimum field energy for calculation and the software marks disturbance area with definite color.

The software can also be very useful for microwave oven link planning. It allows you to display landscape profile between a pair of points, display regarding optical visibility from the point and computation of link parameters. Although this software is free and dedicated regarding amateur radio it could be very useful tool regarding daily radio conversation tasks.
