Abstract

trata-se de técnicas descritas para comunicação sem fio. uma ou mais porções do preâmbulo de rede de área local sem fio (wlan) podem abranger múltiplas bandas de frequência de 20 mhz e, podem ser duplicadas através de uma largura de banda de transmissão. as porções de preâmbulo de wlan podem incluir porções comuns para múltiplos receptores, bem como porções dedicadas para receptores particulares e porções comuns podem ser transmitidas em uma banda de frequência primária em alguns exemplos. algumas técnicas fornecem porções de preâmbulo de wlan que podem ser codificadas com o uso de blocos de código de tamanhos diferentes. vários aspectos da revelação também fornecem sinalização de alocações de recursos de quadros sem fio de wlan.
