HYBRID COMMUNICATION SYSTEM PROVIDING GROUPING, LOCALIZATION AND/OR COMMISSIONING CAPABILITY

摘要

Distinct physical channels in a network are exploited to provide capabilities that go significantly beyond conventional hybrid networks. In a first aspect, distinct physical channels are employed to determine physical relationships of the nodes with respect to each other. For example, whether or not the nodes of an RF wireless system are in the same room of a building can be determined by using optical messages passed between the nodes. In a second aspect, a first physical channel is employed for synchronized broadcasting, and a second physical channel is employed to enhance the capabilities of the synchronized broadcast network. For example, the nodes of an RF wireless broadcast network can be selectively commissioned (i.e., sensitized) with optical signals to commands that are broadcast on the RF network.
