Abstract

"MéTODOS E APARELHO PARA IDENTIFICAR LOCALIZAçãO DE RECURSOS EM REDES DE COMUNICAçãO". A localização de recursos sem fio não modificados em uma rede de comunicação sem fio pode ser identificada usando diferenças de instantes de chegadas de uma seq³ência de comunicação em diferentes receptores da rede. Dispositivos de marcação de tempo podem incluir circuitos correlacionadores em paralelo com decodificadores de sinal para seq³ências de comunicação de marcação de tempo. Redes sem fio celulares podem ser multiplexadas por freq³ência para aumentar densidade de marcação de tempo espacial. Etiquetas podem ser ligadas a recursos passivos para prover informação de identificação de localização para dispositivos de rede. Localizações de recursos radiodifundindo estruturas de freq³ência de rádio 802.11 padrões podem ser identificadas. Ruído inerente na correlação de uma sequência de comunicação pode ser reduzido usando uma função de correlação selecionada.
