Before any campus access point is mounted, the wireless team walks each floor and records signal levels at the classrooms. Which record is that walk producing?
Select an answer to reveal the explanation.
Short Explanation
You would not hang pictures until you had walked the room with a light meter. The team is walking the campus floors and writing down signal before any radio is mounted, and that record is a wireless survey with its heat map. A floor-plan guess, a survey after the radios are up, or a hunt for interferers is a different record.
Full Explanation
A wireless site survey measures the radio environment where clients will stand. Walking the floors and recording signal at the classrooms, before any access point is mounted, is that survey. The heat map is the picture of those measurements. A predictive design from the floor plan can suggest spots, and it has none of the measured signal from this walk. An active survey after the radios are mounted is a real survey of a live system. The stem says nothing has been mounted yet. Spectrum analysis names interferers and does not record classroom coverage. Exam caveat: a desk-only prediction is a guess until someone walks the floor. Operational check: keep the heat map with the mounting plan, and confirm each measured classroom has a signal reading before a radio is installed. A prediction with no walk is not this record, A survey taken after the radios are mounted answers a later question. Spectrum analysis can run the same day and still will not draw the coverage map this walk is producing.
