Described is a communication system (100) including mobile communication devices (119). In the described system, the mobile devices may be wrist-worn watches (101, 121) such as are in common use today, except that the watches are specially configured to receive data in a broadcast mode (109) and transmit and/or receive data in a localcast mode (111). The localcast mode includes the ability to transmit and receive data in a peer-to-peer fashion (117), allowing mobile devices to communicate directly with each other. The ability to combine two of these communication modes in a small, integrated and hence inexpensive and low-power packet provides many advantages over existing personal communication device solutions.
L'invention concerne un système de communication (100) comprenant des dispositifs de communication mobile (119). Dans le système selon l'invention, les dispositifs mobiles peuvent être des montres (101, 121) à porter au poignet, comme celles couramment utilisées aujourd'hui, configurées spécialement pour recevoir des données en mode diffusion étendue (109) et émettre et/ou recevoir des données en mode diffusion locale (111). Le mode diffusion locale permet d'émettre et de recevoir des données d'égal à égal (117), ce qui permet aux dispositifs mobiles de communiquer directement les uns avec les autres. La possibilité de combiner ces deux modes de communication dans un paquet de faible puissance, intégré, de petite taille et donc peu coûteux, présente de nombreux avantages par rapport aux solutions de dispositifs de communication personnels existantes.
