System and method for determining communication paths in a trainline communication network
First Claim
1. A system for determining communication paths in a trainline communication network utilized by a consist, the system comprising:
- a processor configured to;
determine direct data transmission metrics for one locomotive of the consist;
receive direct data transmission metrics based on one or more tone maps for the remaining locomotives of the consist, wherein the one or more tone maps comprise data rate and frequency information;
determine indirect data transmission estimates for the one locomotive based on the received direct data transmission metrics for the remaining locomotives of the consist;
determine communication paths for the one locomotive by comparing the direct data transmission metrics for the one locomotive to the indirect data transmission estimates for the one locomotive; and
send a data transmission to one of the remaining locomotives according to the determined communication paths.

Abstract
A system for determining communication paths in a trainline communication network utilized by a consist has a processor configured to determine direct data transmission metrics for one locomotive of the consist. The processor receives direct data transmission metrics for the remaining locomotives of the consist and determines indirect data transmission estimates for the one locomotive based on the received direct data transmission metrics. The processor determines communication paths for the one locomotive by comparing the direct data transmission metrics for the one locomotive to the indirect data transmission estimates for the one locomotive.
