So they're really already doing what you suggest in the last paragraph... it's just rare to be able to make the decision as to root cause.
I agree and with the logging on the field communications devices off and the robots mostly not logging the power to the radios (cause we were forbidden to do so per the official answer to my Q&A from 2012) there was no way anyone in the FIRST field crew would have had a good quick way to even narrow down on that issue.

Even if they monitor that radio power there are known and not well known programming pitfalls that can swamp the radios so I admit even the above wouldn't be entirely complete.

Quality of service monitoring on field side isn't a perfect solution either because the field channels can be swamped robot side or by the already mentioned wireless issues. One could track packet communications on the WiFi bridge as well but that'll probably require some custom firmware and some place to stick the data.
