Edge Gateway Coverage at 99% edge gateway coverage target: a worked example

What does the result look like when edge gateway coverage target reaches 99%? The full calculation is worked below with real intermediate numbers. Use it when an automation lead is reporting IIoT rollout progress to operations and needs a clean percent-coverage number plus the gap to the target on the rollout dashboard.

The inputs for this scenario

  • Assets connected through edge gateways: 42 assets (unchanged)
  • Total in-scope assets: 60 assets (unchanged)
  • Edge gateway coverage target: 99 % (raised for this scenario; the documented default is 90)

Working through the calculation

  • Applying the documented formula (Edge gateway coverage = connected assets ÷ total in-scope assets × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 70 % for edge gateway coverage, the number this scenario is built around.
  • At this operating point the engine returns 29 points for coverage gap to target.
  • At this operating point the engine returns 42 count for connected assets.
  • At this operating point the engine returns 60 count for total in-scope assets.

How this compares with the baseline

  • Against the tool's baseline example, where edge gateway coverage target sits at 90% and the headline result is 70 %, this scenario lands almost exactly on the baseline at 70 %.
  • A figure at this level is achievable when edge gateway coverage target is genuinely sustained, not just peaked for a shift. It counts an asset as covered if a gateway connects it, not whether the data is complete, high-quality, or actually flowing to consumers downstream.

Results at a glance

  • Edge gateway coverage: 70 % (headline result)
  • Coverage gap to target: 29 points
  • Connected assets: 42 count
  • Total in-scope assets: 60 count
