Link Budget for Android

By Bill Cowley Free

Developer's Description

The user enters link parameters such as transmit power, antenna gains, link distance, bit rate etc. This allows the received signal quality to be evaluated. Many link parameters allow different input options. For example the antenna gain may be given in dBi, or the diameter of a dish antenna in meters. This app deals mainly with digital communication links, rather than analog systems.

This app includes several on-line examples, for satellite and terrestrial communications, plus brief notes on interesting or novel aspects of these links. A link is provided to a short tutorial on link budget parameters and the formulas used in the app. The latest version provides information on the bandwidth options, given the Eb/N0.

The first screenshot shows the parameters required for a new link budget.

Each of the 8 parameters allows appropriate units to be selected, and provides brief hints. After entering suitable parameters, the user presses the "CALC" button to evaluate the link budget. Numerical values (in dB) that contribute to the final Eb/N0 result are shown in the second screenshot which is one of the examples (Ka Band Mars return link).
