Abstract

técnicas para medição de faixa entre uma ou mais estações sem fio (stas) e um primeiro ponto de acesso (ap) são descritas aqui. em várias modalidades, o primeiro ap pode sincronizar um relógio do primeiro ap com relógios de um ou mais aps sincronizados. o primeiro ap pode realizar uma sessão de sincronização com uma ou mais stas. o primeiro ap também pode transmitir um ou mais quadros de momento de partida (tod) de difusão para uma ou mais stas. cada um dentre um ou mais quadros tod de difusão pode incluir um momento de partida de um quadro tod de difusão a partir do primeiro ap. um segundo ap e um terceiro ap dentre um ou mais aps sincronizados também podem transmitir um ou mais quadros tod de difusão para uma ou mais stas para determinação de faixa e/ou posição.
