Wireless site survey
Measuring the physical space to determine where access points should go and at what power.
Walls, mirrors, metal shelving, and lift shafts all affect coverage in ways a floor plan does not reveal. A survey measures actual signal and interference rather than estimating it.
For sites where wireless carries voice or clinical devices, this is the difference between a network that works and one that drops calls in a specific corridor nobody can explain.
Where this comes up
Wireless site survey sits inside our networks and infrastructure work. If you are trying to work out what this means for your own environment rather than in the abstract, that is the page worth reading next, and a short call will get you a straight answer faster than either.
