Abstract
<B>SISTEMA DE COMUNICAçãO CELULAR SEM FIO MULTIPORTADOR<D>. é revelado sistema de comunicação celular sem fio multiportador, no qual estações de base para um agrupamento de duas ou mais células respectivas transmitem a mesma informação de sinalização em sincronismo no mesmo grupo de subportadores. Isto permite a combinação de vários sinais da estação de base "no ar" antes da antena do receptor, sem utilizar qualquer hardware adicional para combinação de sinal no terminal móvel.
