Abstract
"MéTODO PARA DETERMINAR A LOCALIZAçãO APROXIMADA DE UM DISPOSITIVO A PARTIR DE SINAIS AMBIENTE". A presente invenção aperfeiçoa alterações na potência percebida de sinais de rádio em localizações diferentes para determinar a localização de um dispositivo. Em uma modalidade da invenção, procedimentos de inferência são utilizados para processar os sinais de rádio comercial ambientes, para estimar uma localização ou uma distribuição de probabilidade em relação à localização de um dispositivo. Em uma modalidade da invenção, os métodos de aprendizado e de inferência são aplicados junto ao vetor de classificação de vetores de potência de sinal. Mover-se para tais ordenamentos de classificação leva aos métodos que desviam-se da consideração das potências absolutas de sinal nos cálculos de localização. A invenção facilita a aproximação em relação a localizar um dispositivo por proporcionar um método que não requer um número substancial de potências de sinal ambiente disponíveis ao mesmo tempo que ainda proporcionando inferências de localização úteis ao se determinar as localizações.
