Abstract

Un teléfono inalámbrico para ser utilizado en una red de comunicaciones inalámbricas con una disposicion de posicionamiento global. El teléfono comprendeun transceptor de comunicacion inalámbrica con dicha red, un receptor de disposicion deposiciona miento global para adquirir informacion de corto plazo y delargo plazo utilizada para efectuar determinaciones de posicionamiento, y un controlador conectado a ambos, el transceptor de comunicacion inalámbrica y elreceptor de GPS, donde elcontrolado r adapta en forma inteligente su programacion de mantenimiento de datos de GPS de acuerdo a un exclusivo conjunto deindicadores derivados de las condiciones de operacion del teléfono inalámbrico. La presente también propone un método parapreservar l a energía de la bateríade dicho teléfono inalámbrico, en modo de espera, mientras mantiene informacion operativa con dicha disposicion de posicionamiento global que consiste enadquirir una de dichas informaciones de corto y largo plazopor medio de c ambio de receptor al estado de encendido y al estado de apagado en forma repetida yperiodica para obtener informacion de corto y largo plazo al cambiar la frecuencia de adquisicion de una de las informaciones basadas en eventos eneltransceptor.
