Mobile robot teams often communicate reliably in a lab, then develop delayed commands, missing sensor updates, or slow recovery when mesh routes change.
-
When a handheld radio moves out of range, the network must quickly decide how traffic will reach it again. That decision becomes more complex when cameras, sensors, vehicles, and command systems share a changing multi-hop wireless topology with limited airtime.
-
When a patrol vehicle drops behind terrain while several teams request the same video feed, choosing between unicast, multicast, and broadcast becomes an airtime and reliability decision—not a textbook distinction.
-
A UAV data link may look reliable during a short ground test and still fail when the aircraft reaches maximum range, banks, climbs, or carries a high-rate video stream.
-
When a mobile mesh link looks strong on a bench but loses video, latency, or route stability in motion, the problem is often not transmit power alone.
