Best Practices, Tips, and Tricks

· If the WLAN being surveyed has SSID broadcasting disabled, enable it for the duration of the survey, if possible. This will facilitate the identification of the APs you would like to have included in the data analysis.
· Fully charge your notebook and be prepared to recharge it. Having an extra battery on hand would not hurt. However, if your notebook goes into standby or hibernation while you are performing a survey, TamoGraph will save the data and stop the active survey. You will be able to continue where you stopped.
· When you conduct GPS surveys, the survey process is fully automated; normally you do not need to touch any application controls, so you may want to close the notebook lid. If you plan to close the lid, be sure to configure the notebook power settings to prevent the notebook from going into standby or hibernation when you close the lid.
· Plan your walkabout path in advance. You may want to write down numbers on the site map marking your path. Then, while surveying, you would just have to walk along the path and click on these numbers. When planning your path, be sure to plan it so that you capture the perimeters of the rooms rather than their center. This improves data quality.
· If you care about signal leakage outside the building, plan your path along the outside building perimeter. Without this perimeter, TamoGraph will not be able to estimate the signal strength outside the walls.
· Be sure to cover places of special importance, such as conference rooms or the CEO's office. Survey them with closed doors. Closed doors may considerably decrease the signal level, so surveying with open doors may give you a signal coverage map that is too optimistic.
· If the site is large, consider splitting the site map into several parts, as working with smaller maps is easier. Besides, the report generated by TamoGraph will be more meaningful if separate maps are used for separate zones. A large map just will not be legible if has to be displayed on one page. You can have as many maps as you wish in a single TamoGraph project.  The same applies to multi-floor buildings.
· If the site is large, you can also split the job between several people sharing the same project. The correct way of doing this is described in the Survey Job Splitting chapterchapter.
· If you are going to survey a large facility with many employees during business hours, make an announcement telling them that someone will be conducting a survey. Ideally, this will prevent them from distracting you with questions.
