Edge Gateway Coverage at 65% edge gateway coverage target: a worked example

This worked example runs the edge gateway coverage numbers for a tougher week than the baseline: 65% edge gateway coverage target instead of the typical 90%. Estimate the share of plant assets covered by deployed edge gateways from the count of assets connected through edge gateways, total assets in scope, and the program coverage target.

The inputs for this scenario

  • Assets connected through edge gateways: 42 assets (held at the documented default)
  • Total in-scope assets: 60 assets (held at the documented default)
  • Edge gateway coverage target: 65 % (the input this scenario stresses; the baseline uses 90)

Working through the calculation

  • The calculation starts from the formula this tool documents: Edge gateway coverage = connected assets ÷ total in-scope assets × 100.
  • Edge gateway coverage works out to 70 % at these inputs, and this is the headline figure for the scenario.
  • Coverage gap to target works out to -5 points at these inputs.
  • Connected assets works out to 42 count at these inputs.
  • Total in-scope assets works out to 60 count at these inputs.

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 %.
  • Use it in IIoT rollout reviews to report progress and quantify the remaining connectivity gap against a milestone. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Edge gateway coverage: 70 % (headline result)
  • Coverage gap to target: -5 points
  • Connected assets: 42 count
  • Total in-scope assets: 60 count
