Abstract
A new data transmission technique is about to create a revolution in the field of wireless local area networks. This new method, called Ultra Wideband, is based on the transmission of data through the communication channel below the noise floor. It involves transmitting very short duration pulses, which has the effect of spreading the signal energy across a wide frequency range. The objective of this article is to report on the state of the art in this research area, and to outline the main advantages of this promising data transmission method.
Résumé
Une nouvelle technique de transmission de données est en train de révolutionner le domaine des communications sans fil courte portée. Cette nouvelle technique, connue sous le nom de transmission Ultra Large Bande, consiste à émettre les données sur le canal radio en dessous du plancher de bruit. Pour cela, on transmet des impulsions de très courte durée qui vont étaler leur énergie dans une large plage de fréquences. Le présent article a pour objectif de dresser un état de l’art des recherches dans ce domaine ainsi que de mettre en évidence les principaux avantages de cette méthode très prometteuse.
