Predictive coverage and performance is an estimate, and so will be the number and location of APs the tool calls for. It is typically difficult to accurately model all the contents and makeup of a building without physically seeing it, and is especially hard for buildings that have changed or have been remodeled over time and don’t match the floor plan used. The construction of the building still must be known and input into the program. the “leg time” needed for an active survey.Ī predictive survey is advantageous when travel to the location is not feasible or access to the building is not possible. Predictive site surveys may take less time but still require “seat time” in front of a computer vs. What’s more, some of today’s thin APs won’t work without being connected to their controller, which can make surveying more cumbersome as there is more equipment to lug around, and is one of the reasons some integrators may try to push for a predictive site survey. The downside of an active survey is it is more labor intensive and requires physical access to the building. An active site survey also can measure sources of interference or other Wi-Fi networks that may be operating nearby before the network is installed. This type of survey provides more accurate performance information for each AP and allows for the physical inspection of the chosen locations to assure the AP can be mounted there. There is no need to estimate the thickness or density of walls or floors and provide for things like books on bookshelves, file cabinets, mirrors in the bathroom, contents of closets, insulation in walls, and ducts and piping between floors. The application will then predict the number and location of APs required to meet the desired coverage and performance goals.Įach method has advantages and disadvantages: Active site surveys measure the real radio-frequency performance of each AP location and, because they measure real signal propagation, they innately take into account all physical characteristics and contents of the building.
PREDICTIVE WIRELESS SITE SURVEY NETSPOT WINDOWS
Floor plans of the site are imported into the tool and allow the user to assign attenuation values (how much RF energy is absorbed) for walls, floors, cubicles, windows and other objects in the building (most tools typically have a database of materials to choose from).
PREDICTIVE WIRELESS SITE SURVEY NETSPOT SOFTWARE
May require moving APs around or adding more APs after installationĪ predictive site survey uses a software package to simulate the construction of the building.
May require cables to be added or relocated
