1. A method for quantifying idle radio spectrum access across a geographic region, comprising: selecting geo-referenced locations within the geographic region to form a geo-referenced set of observation locations; determining geo-referenced locations of wireless devices inside the geographic location; receiving radio spectrum access parameters for the wireless devices; computing geo-referenced coverage areas for the wireless devices based on the received radio spectrum access parameters and the determined geo-referenced locations of the wireless devices; integrating the computed geo-referenced coverage areas with a representation of radio spectrum dimensionality to form an assessment of multidimensional radio spectrum conditions across the geographic region; computing geo-referenced portions of idle multidimensional radio spectrum access across the geographic region based on (i) the geo-referenced set of observation locations and (ii) the assessment of multidimensional radio spectrum conditions across the geographic region; and configuring a wireless device to operate according to a set of radio spectrum access parameters selected from the geo-referenced portions of idle multidimensional radio spectrum access across the geographic region.
