Abstract: Radio broadcasting equipment is provided that enables targeted radio broadcast advertisement delivery in an radio broadcast area wherein a plurality of radio transmitters are used to transmit broadcasting area wide programming and localized auxiliary information on a single frequency and wherein broadcasting area wide programming is transmitted by at least one of the radio transmitters and localized auxiliary information is transmitted by individual radio transmitters included in the plurality of transmitters.

Abstract: Radio broadcasting equipment is provided that enables targeted radio broadcast advertisement delivery in an radio broadcast area wherein a plurality of radio auxiliary or booster transmitters are used to transmit localized auxiliary information to supplement broadcast area wide content transmitted on the same frequency. Moreover, these auxiliary or booster transmitters are configured to transmit different localized auxiliary information to supplement a plurality of main transmitters transmitted on corresponding specified transmission frequencies using Time Division Multiple Access frame structure.

Abstract: A method and apparatus in a radio communication system (100, 101) provides simulcast control channels for a coverage area (500), and message channels transmitted in coverage zones (502) within the coverage area (500) on a time-division multiplex basis (FIG. 4). A first modulation technique generates (814, 816, 818) each of the message channels at a first average output power substantially less than a peak output power of a transmitter (202). A second modulation technique generates (806, 808, 810) each of the control channels at a second average output power approximately equal to the peak output power of the transmitter (202), thereby increasing usable coverage distance from the transmitter (202) for the control channel compared to the message channel. The control channels are allocated (FIG. 5) to the coverage zones (502) in a staggered geographic pattern such that reception of the control channels is maintained substantially throughout the coverage area (500).
