Geofencing patterns that earn their keep

The noise problem

A geofence that fires constantly stops being an alert and becomes background. Fleets that draw a zone around every customer and alert on every crossing generally end up ignoring the whole channel within a month.

The zones worth keeping are the ones where a crossing implies a decision.

Four patterns that work

Across very different operations, the same four uses keep proving their worth:

• Depot out-of-hours: one zone per depot, alerting only outside working windows, catching unauthorised movement
• Customer dwell measurement: zones around regular sites used for reporting rather than alerting, revealing where loading time is lost
• Restricted areas: a small number of zones where entry is genuinely exceptional and always warrants a call
• Arrival notification: zones used to trigger downstream customer updates rather than internal alerts

Separate reporting zones from alerting zones

The clearest structural improvement most fleets can make is to stop treating every zone as an alert source. Zones used purely for dwell reporting can number in the hundreds without creating any noise, because nothing fires.

Reserve alerting for the small set of zones where someone will genuinely act on the message, apply a schedule to each one, and review which rules fire most often every quarter.
