Give it an island, a district or a trail. It gives back a count, the gaps, the cost and the calendar.
The scope page answers what a kind of place needs. This answers what your place needs. Choose the shape of the problem, set the dimensions, then set the number of units you can actually fund, because the interesting output is not the ideal plan, it is what a partial budget buys and precisely where it leaves people outside coverage. Costs are Estimated at low volume and the caveats at the bottom of the page are the ones that will move a real number.

EstimatedAn island is an area problem. A trail is a line problem. They are not the same arithmetic.
An island cannot buy its way onto an operator's network, but it can own a mesh outright. Positions follow radio line of sight and settlement, in that order.
Ridge and headland positions carry the mesh, settlement positions carry the charging. The two lists overlap less than people expect, which is why the planner returns both a coverage figure and a population figure.

Save this plan, then argue with it side by side.
A plan is only useful next to another one. Save an island at full coverage, the same island at half the budget, and a trail, then read the four columns that actually decide a programme: how many units, how much coverage is bought, what each person reached costs, and how long the whole thing takes. Scenarios are held in this browser only, up to 12, and nothing is sent anywhere.
Save the current inputs
Saving the same name twice keeps both and numbers them, so a revised assumption never overwrites the version somebody has already seen.
No scenarios saved yet. Set the inputs above, give the plan a name, and it appears here for comparison.
Two plans, the same ground, and exactly where they disagree.
A coverage percentage hides the thing a buyer cares about, which is which part of the island or which stretch of the trail stays dark, and for how long. Pick two saved scenarios, walk the rollout in quarters, and the third grid marks every cell where the two plans differ. The geometry is modelled from spacing and shadowing, not surveyed.
Save at least two scenarios above and the side by side maps appear here.
The bench is not the expensive part. Reaching the position is.
On a trail, logistics and a hard anchor can approach the cost of the unit itself, which is why the Wayfarer ships as panels that assemble on site. In a town district both lines collapse and the plan is dominated by hardware.

EstimatedThe limits, published before a buyer trips over them.
Coverage here is modelled from spacing and a shadowing factor, not from a terrain profile. A real island plan needs a line of sight study against elevation data, and that study will move positions.
Consents are the schedule risk, not installation. The mobilisation phase is a flat 30 days on this model and it is the line most likely to be wrong on a public highway.
Costs are Estimated at low volume. Install and logistics both fall materially with a repeat programme in one geography.
Radio licensing differs by country. Where a licence is required for the mesh band, a unit ships with that radio disabled until the licence is held, and the coverage figure on this page does not apply until it is.
No figure on this page has been proven by a deployed fleet, because none is deployed yet.
