Abstract

La presente invención proporciona un método y aparato nuevos que utilizan comunicaciones de espectro ensanchado por saltos de frecuencia. Según un método de la presente invención, se comunica un mensaje de datos mediante un transceptor utilizando comunicaciones de espectro ensanchado, comunicándose cada byte del mensaje de datos un número predeterminado de veces en una secuencia de canales de datos por un transmisor. El método incluye transmitir un preámbulo por un número predeterminado de canales de preámbulo; y transmitir grupos de bytes de datos cada uno de los cuales incluye un subconjunto del mensaje de datos por la secuencia predeterminada de canales de datos.
