The key idea

Useful locations matter more than reaching an arbitrary point count.

Start with the decision, not a grid

There is no single point count that proves every building is covered. A small open room, a divided office and a property with several floors present different questions. Decide which spaces and user activities the survey must support before choosing the route.

A regular grid can help with consistency, but it should not prevent you from measuring an important workstation, meeting area or transition. A point taken where nobody uses the network may add less value than one at the reported problem location.

Cover different conditions

Include the major types of space in the scope: open areas, enclosed rooms and routes between them. Capture a reference position where the experience is normally acceptable. If two areas are separated by a substantial layout change, do not assume one reading describes both.

As you review the first pass, look for gaps and unexpected differences. Use those observations to choose a second pass. Targeted follow-up points often answer a question more efficiently than collecting many more points in an already consistent area.

Recognize the limit of a small evaluation

A four-point evaluation can demonstrate the workflow and compare a few deliberate positions. It cannot certify an entire office, hotel or warehouse. Choose those points to learn how capture, synchronization and reporting work, and state the limited scope of the result.

Wi-Fi Master Planner’s Basic site has a small evaluation allowance. Check the current plan limits before designing a larger field visit. A licensing limit is not an engineering recommendation for how densely a real site should be measured.

Stop when the evidence answers the scope

Review whether every important area has useful evidence and whether unexpected results have been checked. More points are not automatically better if they are stale, misplaced or collected under inconsistent conditions.

Document what was not measured. A clear statement of remaining uncertainty is more useful than a confident-looking floor with unexplained gaps. For a follow-up visit, preserve enough of the route to repeat the most important comparisons.

Take it into the field

  • List the spaces and activities in scope.
  • Include reference, problem and transition positions.
  • Use unexpected results to guide additional points.
  • State the unsampled areas and evaluation limits.
