Abstract

Patente de Invenção: <B>"APARELHO E MéTODO PARA RADIOCOMUNICAçõES"<D>. A seção de determinação da força de transmissão 105 determina um valor da força de transmissão em uma comunicação entre estações proprietárias que não irá interferir com as comunicações entre outras estações baseado no valor da força de transmissão nas comunicações entre as outras estações, a seção de medida SIR 108 mede uma SIR de um sinal de referência conhecido no sinal de recepção e a seção de determinação da taxa de transmissão 109 determina um valor da taxa de transmissão que irá alcançar a qualidade desejada da comunicação de acordo com o valor da força de transmissão determinado e com o valor SIR medido.
