ABSTRACT:
In many systems now in use for sending digital data from a controlled station (e.g., a transmitting station), generally indicated at 10 in FIG.1, to a controlling station (e.g., a receiving station) generally indicated at 12, a plurality of hopping frequencies are provided. In such systems, a first packet is transmitted from the controlled station10to the controlling station12at a first one of the hopping frequencies in the plurality. The data in a second one of the packets is then transmitted from the controlled station10to the controlling station12at a second one of the hopping frequencies. The data in a third one of the packets is subsequently transmitted from the controlled station10to the controlling station12at a third one of the hopping frequencies. The sequence of the different hopping frequencies for use as the carrier for the transmission of the successive data packets from the controlled station10to the controlling station12is known to the controlled station and the controlling station. By providing a sequence of different hopping frequencies for the transmission of successive data packets from the controlled station10to the controlling station, the controlling station12is able to differentiate the data packets, transmitted to it through a communication channel or by wireless, from a vast number of other data packets which are transmitted from other controlled stations to other controlling stations.
