Abstract

<B>MéTODO E APARELHO PARA AVALIAR COBERTURAS PILOTO<D> Método e sistema que minimizam sobreposição de sinal piloto e interferência de freq³ência de rádio ("RF") mediante avaliação de mudanças na cobertura piloto para condições de energia e de carregamento de canal de tráfego diferentes. Quando as estações de base são posicionadas, um terminal para medir intensidades de sinal piloto recebido, tal como uma estação móvel, ou dispositivo de varredura piloto, é usado para coletar e gerar dados de pesquisa piloto e linha de base, os quais são armazenados em um disco ou fita. E~ c~/I~ o~s piloto de transmissão de estação de base, isto é, cargas de canal de tráfego em ligações de envio, são também armazenadas no disco ou fita. A invenção usa dois fatores de ajuste associados com energia de transmissão e carregamento de canal de tráfego para otimizar condições diferentes de RF, especificamente para condições diferentes de carregamento de ligação de envio ou de energia de transmissão de estação de base. Para cada condição de RF, a metodologia calcula as mudanças nos dados de pesquisa piloto de linha de base. Isto reflete quais E~ c~/I~ o~s uma estação móvel receberia sob as condições dadas. Um técnico de sistema coleta um conjunto de ajustes otimizados de energia de estação de base para cada uma das condições diferentes de carga de canal de tráfego. Um desses ajustes otimizados de energia é então selecionado pelo técnico de sistema para cada uma das estações de base.
