  • Digital data broadcasting systems, methods and components that selectively rebroadcast data packets based on analysis of propagation characteristics
    Patent number: 7596108
    Abstract: Digital data broadcasting is performed by analyzing propagation characteristics in a broadcast propagation area to determine a rebroadcasting strategy. Data packets are broadcast, and at least one of the data packets is selectively rebroadcast, to broadcast receiving stations in the broadcast propagation area according to the rebroadcasting strategy that was determined. The analyzing, broadcasting and selectively rebroadcasting are performed independent of receiving acknowledgements that data packets have or have not been received. The rebroadcasting strategy may be determined by measuring a received signal quality of broadcast data packets at multiple locations in the broadcast propagation area and/or by simulation of the propagation characteristics based on a model of the broadcast propagation area.
