Radio Mobile

Radio Mobile is a tool for the design and simulation of wireless systems . it predicts the performance of a radio link by using information about the equipment and a digital ma of the area . it is public domain software that runs on Windows , or using linux and the Wine emulator .

Radio Mobile uses a digital terrain elevation model for the calculation of coverage , indicating received signal strength at various points along the path . It automatically builds a profile between two points in the digital map showing the coverage area ad first fresnal zone . During stimulation , it checks for line of sight and calculatres the Path Loss , including losses due to obstacles . It is possible to create networks of different topologies , including net master / slave , point-to-point , and point-to-multipoint  . The software calculates the coverage areas from the base station in a point-to-multipoint system . It works for systems having frequencies from 100kHz to 200kHz . Digital elevation maps ( DEM) are avaialable for free from several sources , and are available for most of the world . DEMs do not show coastlines or other readily identidiable landmarks , but they can easily be combined with other kinds of data ( such as aerial photos or toppographical charts ) in several layers to obtain a more useful and readily recognizable representation . You can digitize your own ,maps and combine them with DEMs . The digital elevation maps can be merged with scanned maps , satellite photos and Internet map services ( such as Google Maps ) to produce accurate prediction plots .
