Tiling is an optional feature of STI Field Test 7 software and therefore it is an option on the STI-9450 and STI-9400 as well. Tile testing works by dividing a geographic region into equal size rectangles in order to quantify signal coverage. Tiles can be viewed while acquiring signal measurements so the driver knows when a qualifying number of measurements have been made in each tile, validating the test tile. After RF measurement data has been acquired the tile analysis tool will analyze and plot various parameters for each tile such as signal strength, BER and audio quality. The test tiles are analyzed for tile average or the percent of measurements above a threshold level within each tile. Tile reports can be made that show details of the measurements within each tile and/or a summary of the tiles tested. STI Field Test 7 creates an MS Access compatible database of tile statistics which is used by STI Field Test 7 for creating compliance test reports.
