Transmission spectrum selection for locomotive consist communications |
摘要 |
A method for transmitting data between access points in a locomotive consist is disclosed. The method may include determining, at a sending access point, the number of locomotives across which a communication signal will be sent. The method may also include selecting, based on the number of determined locomotives, a first transmission spectrum from among one or more transmission spectrums. The method may further include equalizing the communication signal using the selected first transmission spectrum and sending the equalized communication signal to a receiving access point. |

1. A method for transmitting data between access points in a locomotive consist, the method comprising:
determining, at a sending access point, the number of locomotives across which a communication signal will be sent; selecting, based on the number of determined locomotives, a first transmission spectrum from among a plurality of transmission spectrums; equalizing the communication signal using the selected first transmission spectrum; sending the equalized communication signal to a receiving access point; and monitoring a characteristic of a communication line over which the equalized communication signal is transmitted, wherein the monitored characteristic includes an operation as a master clock synchronized with one or more other clocks operating in the consist. |
