The objective of this paper is to work out the capacity planning of fixed point-to-multipoint radio data networks, and to present both a universal and an invidual (made by me) model that are closely related. To demonstrate their adaptability, I show a practical example.

Firstly, after getting acquainted with the planning of radio data networks and their universal elements, I estimate the theoretical capacity by the necessary parameters.

I also take into account the effects of signal propagation and the technological solutions, such as the signal-to-noise ratio, error rate of forwarded data units, different modulations and coding methods – since each influences data speed.

With regard to the factors mentioned above, I estimate the data speed of WiMAX technology, and make practicable calculations. Then, the final results will be compared with the standard’s values.

As a next step, I intend to demonstrate the adaptability of both the specific technology (WiMAX) and my own model for the capacity of fixed point-to-multipoint radio data networks.

I aim to show and analyze the features of the algorithmic solutions of the theoretical model step by step.

Finally, I evaluate the result of the practically optimized model, and compare it with present suppliers’ wideband solutions. As a last step, I deal with analyzing their advantages and disadvantages from the point of view of practicability.
