Abstract

são descritos métodos e sistemas para sincronizar relógios mantidos em diferentes dispositivos em uma rede de comunicação sem fio. um primeiro dispositivo transceptor sem fio pode receber uma ou mais mensagens a partir de um segundo dispositivo transceptor sem fio com parâmetros indicativos de um primeiro estado de relógio. o primeiro dispositivo transceptor sem fio pode então sincronizar um segundo estado de relógio mantido no primeiro dispositivo sem fio com base, pelo menos em parte, nos um ou mais parâmetros indicativos do primeiro estado de relógio.
