Abstract

trata-se, de modo geral, de comunicações sem fio e, de modo mais particular, de sistemas de wi-fi que incluem extensões de quadro em quadros de transmissão. os comprimentos das extensões de quadro podem ser determinados com base em larguras de banda de transmissão e taxas de dados de transmissão dos quadros. os comprimentos das extensões de quadro também podem ser determinados com base em uma quantidade de dados úteis em um símbolo final do quadro. um ponto de acesso (ap) pode determinar comprimentos de extensões de quadro para uso na transmissão a estações (stas) com base em capacidades de recebimento das stas. um ap pode determinar comprimentos de extensões de quadro para stas para usar em quadros de transmissão.
