ABSTRACT:
The present invention provides a megacell100,which is divided into a plurality of picocells102.Each picocell102is serviced by a secondary base repeater node configured to transmit to any of three adjacent picocells102.The base station106acts both as an originating information signal source and as an originating base station for transmitting a command signal. The command signal is a narrowband signal, which can be transmitted on a channel with sufficient range to reach the entire megacell. The information signal is a broadband signal with a short range picocell, which is transmitted from a secondary base repeater node to its adjacent neighbors.
