If they did, the containers at the bottom of the stack would be blocked from getting a GPS signal.

Last time I looked into this, which was over a decade, some of the containers at the top could have GPS and ZigBee, and would relay their position to the other container using ZigBee.

I also remember that the company I worked for, I was told that we paid a premium to have our containers placed lower on the stack, in the event something like in the article occurred.
