Radio Mobile – Free Radio Planning Software

Radio wave propagation is a really advanced course of. It’s unattainable to exactly predict how waves will unfold and what values we’ll measure at some explicit level. Subsequently we’ve got some mathematical fashions to approximate radio propagation and to calculate subject power values in accordance with predefined chance.¬†Read more about¬†mobile software


The propagation mannequin, which relies on electromagnetic idea and on statistical evaluation of each terrain options and radio measurements, predicts the median attenuation of the radio sign as a operate of distance and the variability of the sign in time and in house. Propagation fashions outline curves and formulation. With such mannequin we will predict propagation in arbitrary distance from the transmitter.

Utilizing curves and mathematical formulation manually is a really robust job. In an effort to automate and pace up such calculations many software program instruments had been developed. Usually, radio planning software program packages are utilized by broadcasters, cell operators and radio frequency authorities. Due to complexity and small variety of potential prospects, the worth of such software program bundle might be fairly excessive. However there’s one exception to this rule.

Radio Cellular is a software program device for radio propagation calculation. The creator has determined to publish it below the “freeware” license which signifies that the software program is freely accessible on the net. This software program is primarily devoted to beginner radio, nonetheless, it may be additionally utilized in different areas together with broadcasting and professional cell communications.

Calculations are based mostly on the Longley-Rice propagation mannequin. It is a basic function radio propagation mannequin for frequencies between 20 MHz and 20 Ghz. In an effort to use the software program you additionally want terrain mannequin knowledge. This knowledge is required for calculations of efficient heights that are wanted to carry out propagation calculations. You could find some terrain mannequin knowledge sources on the net. They provide free DTM (Digital Terrain Mannequin) knowledge which is sufficient to begin working with the Radio Cellular.

Radio Cellular helps many fancy options like chance to make use of DTM in varied codecs (DTED, SRTM), additionally in lots of layers with totally different decision, chance so as to add map photos in raster format (BMP, JPEG, GIF, TIFF, PNG), chance to calculate interference between radio stations and many features to customise the view.

Primary means of use consists of coming into radio stations with all parameters (if they aren’t entered but) and calculation of the protection. Right here you’ve gotten numerous choices to customise the calculation and consider. Outcomes might be saved for later use. It is usually potential to outline calculation step for coarse calculations to avoid wasting time.

For consequence show it’s normally not sufficient to show it on the grey scale DTM. You’ll in all probability wish to see it on some map. For this function you need to use any map image with identified coordinates. The software program means that you can enter coordinates for every image with a view to show it appropriately over the DTM.

A really helpful operate is the calculation of interference between radio stations. You outline safety ratio and minimal subject power for calculation and the software program marks interference space with predefined shade.

The software program can also be very helpful for microwave hyperlink planning. It means that you can show terrain profile between two factors, show of optical visibility from any level and calculation of hyperlink parameters. Though this software program is free and devoted for beginner radio it may be very great tool for each day radio communication duties.
