Radio Mobile - Free Radio Arranging Software
Radio wave dissemination is a very complex course of action. It is impossible to precisely predict how ocean will spread and just what values we will calculate at some distinct point. Therefore we have some mathematical models for you to approximate radio reproduction and to calculate industry strength values in accordance with predefined probability.
The propagation model, that's based on electromagnetic principle and on statistical examination of both surfaces features and stereo measurements, predicts the median attenuation of the radio signal as a purpose of distance and the variation of the signal soon enough and in space. Propagation models define shape and formulas. With such model we can foresee propagation in irrelavent distance from the transmitter.
Utilizing curves and numerical formulas manually is a very tough task. So that you can automate and accelerate such calculations many software tools were developed. Normally, radio preparing software packages are used by broadcasters, mobile operators and also radio frequency authorities. Because of complexity and very few potential customers, the price of this sort of software package can be quite high. But there is one particular exception to this principle.
Radio Mobile can be a software tool for radio propagation calculation. Mcdougal has decided to publish it under the "freeware" license meaning that the software is readily available on the web. This software is especially 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 dissemination model. This is a general purpose radio dissemination model for frequencies between 20 Megahertz and 20 Ghz. In order to use the software in addition, you need terrain design data. This details are needed for calculations of effective heights which are needed to perform dissemination calculations. You can find a number of terrain model information sources on the web. They feature free DTM (Digital Terrain Model) data that is enough to start dealing with the Radio Mobile.
Stereo Mobile supports a lot of fancy features like possibility to use DTM in various formats (DTED, SRTM), also in numerous layers with different decision, possibility to add map pictures in raster file format (BMP, JPEG, GIF, TIFF, PNG), possibility to calculate interference between the air and lots of functions a customized view.
Basic method of use consists of coming into radio stations with all guidelines (if they are not came into yet) and formula of the coverage. Right here you have a lot of options to customize the calculation and look at. Results can be rescued for later use. It is also possible to define calculation action for coarse data to save some time.
With regard to result display it is usually not enough to display that on the gray range DTM. You would probably like to see the idea on some map. For this purpose you can use any map picture using known coordinates. The application allows you to enter harmonizes for each picture so that you can display it effectively over the DTM.
A very beneficial function is the calculation of interference among radio stations. You outline protection ratio as well as minimum field energy for calculation along with the software marks interference area with defined color.
The software is additionally very useful for microwave oven link planning. It enables you to display ground profile between 2 points, display involving optical visibility on the point and computation of link variables. Although this software is totally free and dedicated with regard to amateur radio it is usually very useful tool pertaining to daily radio connection tasks.
