Indoor RF (Radio Frequency) coverage is very important, but its evaluation doesn’t yet contain any standard. Indoor RF coverage assessment or prediction caught interest of communications researchers and samples collection methods used in data validation should be closely chosen. Usually, RF signal propagation is impacted by internal or external factors such as building materials, relay station position and calibrated RF propagation models. The purpose of this research is to allow telecommunications regulators, operators or RF coverage assessment owners, to objectively evaluate 3G (Third Generation) and 4G (Fourth Generation) mobile networks indoor radio frequency coverage. Several steps have been considered such as, itinerary length optimization using SDTR (Special Drive Test Routes), limits of the use of RF propagation models in indoor scenario, comparison between RDTR (Random Drive Test Routes) and SDTR applied to indoor scenario and finally, list of additional key performance indicators that should be considered.

This paper proposes a new methodology for assessing global coverage of multi-technology mobile networks. The goal is to determine global degree of appreciation of the level of coverage of a given operator public network. The proposed approach examined existing methods, analysed their strength and limitations and compare against selected case studies (survey data). Three cases of radio coverage have been considered with appropriate formulas introduced. These are coverages of combined technologies over the same territory, combined technologies over same population, and combined technologies aggregating both territory and population. Mathematical model was used to calculate the combined coverage ratings. The result shows that the new proposed global assessment methodology is unified, objective and...
