Abstract

Un sistema de comunicaciones que utiliza ondas electromagnéticas. El sistema de comunicaciones opera de preferencia en las frecuencias de ondas-milimétricas y proporciona una resolucion y aislamiento de señal relativamente elevados. El sistema de comunicaciones puede usar diversidad de polarizacion para incrementar la capacidad de un canal. Las características de aislamiento y restauracion en los transceptores eliminan y reducen los efectos de precipitacion y/o refleccion y difraccion de objetos, y este modo, es bien apropiado para un ambiente urbano.
