Fit-test retail edge before the platform PO: label the edge class, split must-survive-WAN-loss workloads, prove the offline money path, then inventory honesty and fleet ownership.
Fit-test an industrial LTE router for a remote cabinet or pad: label the WAN job, survey at the install point, specify failover detect, and design remote access before you shop logos.
Label the failure mode first: band steering, separate SSIDs, guest isolation, DHCP, mesh stickiness, and cloud false alarms before you buy another mesh node.
