Appendix X: Drive Study
Overview
The Drive Study is performed to confirm Base Station coverage. It is used to validate that the
Base Station can be “seen” by a Modem throughout its predicted coverage area.
The RF coverage analysis displays areas of coverage from “good” to “bad” by the use of color-
coding. An RF coverage analysis and its legend may be seen in Figure X1. The legend on the left
displays the decibel strength for a given area, with red designating ‘good coverage’ and white
designating ‘bad coverage’. The RF coverage analysis is used to map out the Drive Study route
(Figure X2), along with geographic areas of concern. You should pay particular attention to null
(white) areas and the cell edges.
