SYSTEM AND APPARATUS FOR PERFORMING BROADCAST AND LOCALCAST COMMUNICATIONS |
摘要 |
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. |
