Resumen (es_ES)

Las comunicaciones inalámbricas actuales, en el bucle del abonado, tienen un cuello de botella que es su baja velocidad (9600 bps); esto impide que se implementen nuevos servicios vinculados a Internet y a la transmisión de datos e imágenes ó hace que aparezcan con limitaciones, como ocurre con los servicios WAP (WIRELESS APPLICATION PROTOCOL). La red de telecomunicaciones actual evoluciona hacia la consecución de una red unificada (red alámbrica y red inalámbrica); la evolución de la red contempla la evolución de los elementos que la configuran; por consiguiente, la parte de acceso tendrá que evolucionar para hacer posible más y mejores comunicaciones entre extremos, sin impedir que los demás hagan lo propio. Los esquemas de acceso inalámbrico de banda ancha propuestos para comunicaciones celulares de tercera generación buscan responder a este desafío. De ellos, W-CDMA y CDMA2000 se imponen como las tecnologías de acceso de mayor eficiencia.

Resumen (en_US)

The current wireless communications have a bottle neck because their low speed (9600 bps); this prevents that new services shall be implemented linked over Internet and the transmission of data and images or he/she makes that they appear with limitations, like it happens with the services WAP (WIRELESS APPLICATION PROTOCOL). The net of current telecommunications evolves toward the attainment of an unified net (wire net and wireless net); the evolution of the net contemplates the evolution of the elements that you/they configure it; consequently, the access part will have to evolve to make possible more and better communications among ends, without preventing that the other ones make the own thing. The outlines of wireless access of wide band proposed for cellular communications of third generation look for to respond to the challenge. Of them, W-CDMA and CDMA2000 are imposed as the technologies of access of more efficiency.
