Abstract: Radio network planning and dimensioning have significant impact on the overall system capacity of the cellular communication systems. Various commercial network planning and dimensioning tools with different radio signal propagation models implemented are available on the market. Their price and especially inflexibility led us to look for an open-source solution. The present paper describes usage of the open-source Geographical Resources Analysis Support System (GRASS) for the radio signal coverage calculation. GRASS modules calculating radio coverage prediction for a number of different radio channel models were developed which, together with module considering antenna radiation pattern influence, compute radio signal coverage for a defined cell. The complete network coverage is computed with modules for generating a data base table (e.g. MySQL, PostgreSQL), arranging the values in increasing order and determining maximal received power at each receive location. A!
dditional modules for adapting input data and analyzing simulation results were also developed. The radio coverage tool accuracy was evaluated by comparing with results obtained from a dedicated professional prediction tool as well as with measurement results.
