Abstract
<B>MéTODO DE TRANSMISSãO SOBRE UM ENLACE SEM FIO<D> Sistema de controle de potência para um sistema de comunicações sem fio que ajusta a potência a transmitir de um transmissor sem fio em relação a uma quantidade de confirmações esperada para radio-transmissões sobre um enlace sem fio. Por exemplo, uma unidade sem fio monitora a quantidade de confirmações que ela recebe (ou falha em receber) quanto aos radio-pacotes que a unidade sem fio transmitiu sobre o enlace sem fio. A unidade sem fio determina a quantidade de confirmações perdidas em relação à quantidade de confirmações esperadas a ser recebido pela unidade sem fio. A quantidade de confirmações esperadas pela unidade sem fio pode ser baseado no número de radio-pacotes transmitidos pela unidade sem fio. Se a quantidade de ACKs perdidas/quantidade de ACKs esperadas for maior do que um primeiro limite, a unidade sem fio aumenta o nível de potência a transmitir. Se a quantidade de ACKs perdidas/quantidade de ACKs esperadas estiver abaixo de um segundo limite, a unidade sem fio diminui o nível de potência a transmitir.
