Abstract

"SISTEMA DE COMUNICAçãO SEM FIO COM VARREDURA DO FEIXE DE ESTAçãO BASE". Um método e aparelho para comunicações sem fio em que uma estação base (102) transmite um sinal para enviar dados para uma estação de assinante (108) através de um feixe de sinal (110) que varre através da área de cobertura da estação base (102). Os dados do usuário endereçados a estação de assinante (108) são armazenados até que o ângulo do feixe de sinal do feixe de sinal (110) permita eficiente transmissão. A estação base (102) pode alterar a velocidade de varredura do feixe ou a forma do modelo de irradiação do feixe (106) no tempo para maximizar a eficiência e capacidade do sistema.
