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.
