How do you support field technicians working in areas with spotty connectivity?

Question

Accepted Answer

Devices are managed and updated remotely, apps are set up to work offline where they can, and we troubleshoot without making a tech drive back to the shop. Coverage in this part of Florida thins out fast once a crew is west of Middleburg, out past Callahan, or down in the rural parts of St. Johns County. We set field devices up so that matters less. Field apps configured to work offline where the software supports it, so a tech keeps working and syncs when signal comes back App and operating system updates pushed remotely on a schedule, instead of whenever a tech happens to notice a prompt Remote support on the device itself, so we can see what the tech is seeing from our office Cellular plans and hotspots reviewed against where your crews actually work, not where the coverage map says they do The failure mode we watch for is the silent one. A tablet that has quietly stopped syncing for two days causes more damage than one that is obviously broken, because nobody finds out until the invoicing does not match the work. Monitoring is set up to surface that. A truck roll back to the office to fix a tablet costs you a service call. That is the thing we are trying to prevent.
