At the moment, the cellular networks are being used as an option to provide broadband services in places that have not yet been covered by the fixed networks, mainly in underdeveloped countries like Brazil. The employed technologies now in Brazil, GSM (Global System is Mobile) and UMTS (Mobile Universal Telecommunications System), they were not developed to absorb the great demand that has been observed at the broadband mobile market. Due to that unexpected demand, it’s being believed that LTE (Long Term Evolution), the first technology developed with the objective of supporting not only the voice calls, but mainly the broadband connections, is able to hold with larger efficiency this growing needs. For all that expectations about the LTE network’s capacity be achieved, it is extremely necessary that a correct sizing of those networks be accomplished, therefore only this way it will be possible to establish the commitment of supporting the subscribers with quality.
