Abstract
A data collection and evaluation method for determination of wireless signal propagation from an incomplete set of measured data. The present invention decodes digital identification information on the channel used to associate the measurement with a wireless antenna and/or sector. The decoding process is limited by interference and low signal levels, therefore, the resulting data will have locations or entire areas where digital identification codes cannot be determined and the signal origination antenna cannot be identified. The present invention introduces geostatistical data interpretation techniques to determine the signal level values at the missing measurement locations. The present invention can obtain a more complete set of data for all sectors in the data collection area, allowing for more accurate performance evaluation and greater planning information. The present invention teaches the application of variogram modeling and kriging for wireless signal propagation modeling.
