Abstract

Una disposicion y método de comunicaciones sin cable, donde la disposicion 100 tiene una oficina central 102 que genera una senal. Unaprimera estacion de base 104 recibe la senal de la oficina central y trasnmite una primera senal der adioemision en un primer rango de frecuencia en respuestaa la senal de la oficina central. Una segunda estacion de base 124 recibe la primera senal de radioemision y transmite una segunda senal de radioemision enun segundo rango de frecuenciaen r espuesta a la primera senal de radioemision. Una tercera estacion de base 134 recibe la segunda senal de radioemision ytrasnmite una tercera senal de radioemision en el primer rango de frecuencia en respuesta a la segunda senal de radioemision.De ac uerdo con la presenteinvencion, una pluralidad de estaciones de base son cada una capaces de proveer una comunicacion de una vía o de dos vías hacia una pluralidad de usuarios 110,130 y 140, con solamente una estacion de base 104 que recibesenales directamente desde la oficina central 102.
