A method for operating a pager network that transmits to a plurality of pager receivers, wherein each pager receiver is accessible in at least one of a plurality of sectors by a selected one of a plurality of channels, wherein each said sector corresponds to one of said channels, and wherein each pager receiver is switchable between an active state and an inactive state, said method comprising the steps of:

  • a) developing a schedule of transmissions addressed to various pager receivers of said plurality of pager receivers, said schedule taking account of which of said sectors can be accessed simultaneously and which cannot be accessed simultaneously due to interference; and

    b) transmitting, to said plurality of sectors via all of said plurality of channels within a time interval, a simulcast message commanding each of said various pager receivers to switch to said active state in accordance with said schedule so that each of said various pager receivers is in said active state to receive its transmission and in said inactive state when there is nothing to receive.
