Fleet network and Wi-Fi coverage

Requirements

The fleet manager requires RSSI of -70 dBm or better along all routes. Between -70 and -80 dBm roaming may be slow; below -80 dBm heartbeat timeouts (E-NET-601) are likely.

Diagnosing coverage problems

• Timeouts on several robots in the same zone: infrastructure problem. Check the access point serving that zone (power, channel, firmware) and run a site survey.

• Timeouts on one robot everywhere: robot-side problem. Check the Wi-Fi antenna cable and client firmware.

• Timeouts at zone boundaries only: roaming thresholds too low, adjust roaming RSSI trigger.

Mitigation

Robots keep executing their current mission during short outages, so the business impact is missed dispatches and delayed status updates. Typical fixes are moving or adding an access point, or switching to a less congested 5 GHz channel.
