ABSTRACT:
A method is provided for increasing the effective transmission range for ones of a plurality of low-power transmitters arranged in an array. In particular, the low-power transmitters are arranged to simultaneously transmit a common information stream, and the transmitters are caused to transmit in a coherent manner. The resultant transmitted energy, as received at a receiver established to receive such transmissions, is thereby increased as a function of the number of operating transmitters.
