Abstract

Un método para controlar los receptores de diversidad de un dispositivo de comunicaciones inalámbrico incluye los pasos de: determinar si el dispositivo de comunicaciones inalámbrico experimenta cobertura deficiente (220); usar primer receptor y un segundo receptor de diversidad (230), si el dispositivo de comunicaciones inalámbrico experimente cobertura deficiente; y usar el segundo receptor para explorar (240), si el dispositivo de comunicaciones inalámbrico no experimenta cobertura deficiente. De manera que la diversidad puede usarse, segun sea necesario, para mejorar la recepcion. Ambos receptores sin embargo pueden usarse en un modo que no sea de diversidad para reducir el consumo de energía o acelerar la adquisicion de canal cuando no es suficiente la cobertura.
