Map real users and devices
List expected client density, roaming paths and locations where building equipment relies on wireless. A floor plan alone cannot show competing RF and load.
Measure challenging areas
Walk shelves, corridors, meeting spaces and outdoor zones as relevant. Note walls, machinery and nearby networks that affect coverage and interference.
Validate after deployment
Repeat representative roaming and throughput checks with customer IT. Save access-point locations, switch ports and configuration ownership.
Working example: The scenario below is illustrative. It describes a practical design and review method, not a completed customer project or a guaranteed result.
A working scenario
An access point survey after hours finds clean coverage, but shelving and occupied meeting rooms alter service during normal operation.
The decision to make before buying
Map client density, roaming route, interference, building materials, access-point mounting, PoE and critical device use. Define the expected performance under normal occupancy.
A useful acceptance test
Walk representative client paths at busy and quiet times; record signal, channel conditions, roaming, throughput or application behavior relevant to the scope.
What the owner should receive
Document heatmaps with dates, AP and switch IDs, excluded zones, settings owner and a plan for re-survey after layout changes.
Questions owners ask
Why survey at several times?
RF conditions and user load change with people, temporary equipment and neighboring networks. A clean empty-room map may miss roaming failure in a crowded corridor or poor coverage behind stocked shelving. Use the hours and paths relevant to the building's actual devices.
What makes survey results useful later?
Record AP placement, channel and power settings, client device type, date, occupancy and the measured application behavior. An unannotated heatmap cannot explain whether a later layout change caused a new dead zone.
