Abstract

TRANSMISSOR SEM FIO E MéTODO DE TRANSMISSãO SEM FIO. A presente invenção refere-se a um transmissor sem fios para infalivelmente distribuir dados para um receptor sem fio, isto é, um receptor de distribuição múltipla ou radiodifusão, enquanto aumentando a capacidade do sistema ou a capacidade de acomodação do canal individual. Um dispositivo estação base (100), o qual é o transmissor sem fio, que distribui de forma múltipla ou difunde por rádio dados endereçados para dispositivos estação móvel (150) através de um canal físico comum. Neste dispositivo, uma seção de recepção de canal individual (103) adquire informação de qualidade de recepção em relação a cada receptor sem fio (150), uma seção de seleção de subportadora de canal comum (107) estabelece de forma comutável um subcanal utilizado para distribuição múltipla ou radiodifusão de acordo com a informação de qualidade de recepção adquirida pelos subcanais do canal físico comum e uma seção de controle de potência de transmissão (110) que controla a potência de transmissão do subcanal estabelecido.
