Radio Mobile for easy site survey


Radio Mobile For Windows (RMW), i think this software very use full for us, most wireless enginering use this software.
RMW, is free software (open source). But even is free, this software still have used for most wireless eng.

i'am use this software beside d'other software like mapsource, global mapper, track point, and so on.
in this post i like share about usefull of RMW, sort story of RMW, create by Roger Coudé, VE2DBE.
This is a Radio Propagation simulation program which operates over the frequency range of 20MHz to 20GHz. It is based on the ITS (Longley-Rice) propagation model. The program enables maps to be drawn of specified areas using downloaded SRTM data from the Space Shuttle Radar Terrain Mapping Mission, elevation contours and roads to be added, then Units (stations) can be placed where required. Individual Unit performances can be specified for power, sensitivity, antenna parameters etc. and all Radio Links examined for path profile and signal parameters. Signal coverage patterns can be produced for each separate unit if required. The 'Best Sites' to provide radio coverage to a number of specified unit locations can also be found. The performance of a radio unit which is traversing a defined route on the map can also be generated by the new 'Route Radio Coverage' feature. It is also possible to find the 'Best Unit' from a selection to give the maximum signal level at a defined location.
Radio Mobile is a free and powerful tool for plotting RF patterns and predicting the performance of radio systems. Using freely available terrain elevation data it can produce grey scale, x-ray and rainbow colored virtual maps. One can also produce 3-D and stereoscopic views as well as flyby animations. Background images can be merged with scanned maps, satellite photos and Mapquest maps to produce accurate prediction plots. You can obtain your copy of Radio Mobile from the official website.

When I first began using Radio Mobile I had to spend a great deal of time with the documentation trying to figure out how everything worked. Once I became familiar with the software I thought that others might benefit from my experience and so this tutorial was born. This tutorial will walk you through obtaining and installing the software, obtaining elevation data and finally plotting simple RF plots. Once you become familiar with the software it becomes very easy to use and is a very powerful tool. I used Radio Mobile to plot coverage and design radio links for customers when I owned a wireless ISP. Radio Mobile was able to create plots that were as accurate as the plots from expensive commercial packages used by my hardware vendors.

Radio Mobile is under constant development so if it is missing a feature you want you may have to wait only a short time before it is added to the software. Please realize that I am only a user of the software, not a developer. Please direct any inquiries regarding the software to the author Roger Coudé.
As stated before I am not in any way affiliated with the author of this software. While I may be able to answer some of your questions I simply do not have the time to provide technical support for Radio Mobile. You may find it beneficial to subscribe to the Yahoo! Discussion Group for Radio Mobile. If you find this documentation useful please provide feedback so that it can be improved.
