Gathering Site Requirements and Information
Make a preliminary visit to the site to gather information described in this section.
Obtain a Floor Plan
Obtain a floor plan with a distance scale and note the following items on the drawing:
Metal walls or concrete walls greater than 1M thick
Large metal objects, such as cabinets and machines
Radio frequency sources, such as RF welders and WiFi
Stairwells or similar openings where floor-to-floor transmissions might be enhanced (for multi-floor
Identify Interference Sources
Check the customer for any pre-existing DECT use, such as a large number of DECT headsets or
