SYSTEM AND METHOD OF COMMUNICATION USING AT LEAST TWO MODULATION METHODS

摘要

A device may be capable of communicating using at least two type types of modulation methods. Methods and systems are provided for communication of data according to a communications method in which a master transceiver communicates with one or more slave transceivers according to a master/slave relationship. A first data message may include first information and second information that are modulated according to a first modulation method. The second information may include lower data rate data. A second data message may include third information that may be modulated according to the first modulation method and that may indicate an impending change to a second modulation method. The second modulation method may be used for transmitting fourth information, and the fourth information may be included in the second message. The fourth information may include higher data rate data, for example Internet access data.

主权项

1. A communication system, comprising:
a transmitter capable of transmitting at least two modulation methods, wherein the at least two modulation methods comprise a first modulation method and a second modulation, wherein the second method is different than the first modulation method, and wherein the first transceiver is configured to transmit
a first sequence, in the first modulation method, that indicates an impending change from the first modulation method to the second modulation method, anda second sequence, in the second modulation method, wherein the second sequence is transmitted after the first data sequence.
