Drive Test
The document outlines the process and importance of RF surveys in determining optimal locations for BTS cell sites and towers to enhance mobile coverage. It details various surveys, tools, and methodologies used for both planning and post-launch optimization of wireless networks, including drive tests, data analysis, and performance measurement. Key parameters and techniques for assessing signal quality and coverage, such as RX level, BER, and sector orientation, are also discussed.

- 1. RF Survey iscarried out to find out best suitable position for BTS cell site and Tower giving best desired result for RF. RF survey is done after RF Planning. RF Planning data is created based on indoor outdoor coverage criteria in the circle where mobile services are to be provided. RF survey is important because it gives the visual details to the RF Planner. Based on these details RF Planner can create better model for providing better coverage.

- 8. Drive Tests andPropagation Prediction software are the two methods that are used to check the coverage area of a particular wireless system. Generally prediction software is used in conjunction with the radio signal measurements in order to determine an accurate picture of signal propagation. In some cases, field measurements may be needed to be taken in order to calibrate the prediction software.
