Abstract

trata-se de um alcance entre um primeiro dispositivo sem fio e um segundo dispositivo sem fio que é estimado usando um primeiro mecanismo com base nas mensagens transmitidas por um primeiro canal de comunicação. o primeiro canal de comunicação é associado a uma primeira capacidade de tecnologia de acesso via rádio dos dispositivos sem fio. obtêm-se uma ou mais métricas indicativas de uma precisão das estimativas de alcance proporcionadas pelo primeiro mecanismo. um segundo mecanismo para estimar um alcance entre o primeiro dispositivo sem fio e o segundo dispositivo sem fio pode ser implementado em favor do primeiro mecanismo quando a métrica não for capaz de satisfazer um critério. o segundo mecanismo se baseia em mensagens de difusão única transmitidas por um segundo canal de comunicação. o segundo canal de comunicação é associado a uma segunda capacidade de tecnologia de acesso via rádio dos dispositivos sem fio e pode ser igual ao primeiro canal de comunicação, ou diferente do mesmo.
