ABSTRACT

When a remotely controlled work machine loses a wireless connection on a work
site, operation of the work machine should be terminated for safety purposes.
However, if the work machine is moving when the wireless connection is lost,
the work machine will continue moving for some time due to inertia.
Accordingly, embodiments predict the signal quality of a wireless connection
as a work machine approaches a new geographical location. When the predicted
signal quality is low, the work machine may be proactively derated before it
enters the geographical location. After entering the geographical location, if
the actual signal quality is significantly better than the predicted signal
quality, the work machine may be rerated. The predicted signal qualities may
be determined based on a signal map that is independently maintained and
updated by each work machine, so as to evolve over time with the work site and
the work machine.
