Abstract

"SISTEMA E PROCESSO DE TELECOMUNICAçãO E, ESTAçãOBASE". Um sistema de telecomunicações sem fio suscetível detransmitir as informações desejadas para uma pluralidade deestações móveis eficientemente é adaptado para transmitir asinformações para a pluralidade de estações móveis formando umfeixe de sinal que cobre estas estações móveis de formasimultânea. Uma vez que as informações podem ser assimtransmitidas para uma pluralidade de estações móveis ao mesmotempo, é possível transmitir as informações de uma maneiraaltamente eficiente. Além disso, devido à potência de transmissãopoder ser reduzida, a interferência atuante sobre outras estaçõesmóveis pode ser suprimida.
