Methods and apparatus for transmitting packets from a source of such packets to one or more radio station sites so that the radio station sites can transmit the packets at the correct real time. Each radio site has an independent source of exact time based on the reception of signals derived from satellite inputs. Using the real time calculated by a base station, the base station calculates an offset between the time of arrival of a signal with a specified time marker, and the time that a signal with that specified time marker should have arrived in order to be transmitted in a timely fashion. The offset is sent back to the source of packets, and used by the source of packets to advance, or retard, the transmission of future packets. Advantageously, packets can be transmitted from each base station at the correct time, and if packets are being transmitted for a given call from several base stations, can be transmitted simultaneously, by these base stations.
