Patent ID: 8229441

Claim:
A method for providing a graduated single frequency network comprising: providing a plurality of transmitters throughout a desired geographic area to form a plurality of cells of the network; and broadcasting data of the network from each of the plurality of transmitters such that adjacent cells of the plurality of cells of the network transmit the data in corresponding transmission signals that reinforce one another wherein: for different cells among the plurality of cells of the network that are adjacent one another, the transmission signals are different from one another yet configured to reinforce one another through over-the-air combining of the different transmission signals broadcast from the different cells at a same time along boundaries of the different cells among the plurality of cells of the network, and for like cells among the plurality of cells of the network that are adjacent one another, the transmission signals are essentially the same and reinforce one another through over-the-air combining along boundaries of the like cells among the plurality of cells of the network.
