1. Google Earth Utility Google Earth Utility is an Excel Based Macro that plots the Cell Coverage Based on TP/TA values on Google Earth. Moreover, it also plots the 2G/3G/4G neighbors and various thematic based on Traffic, Drop Call Rate and Minutes per drops.
The tool is extremely important to propose optimum redesign recommendations which are the core to the optimization process.
1. TA/TP Based CoverageThe tool displays the coverage of both GSM and UMTS based on the TP/TA Statistics. The Color Theme used for plotting TA/TP Bins is mentioned in the table below.

It displays the Frequency, HBA and MPD of the cells in-front of it.
Frequency Labels HBA Labels
MPD (Minutes per Drop) Labels
1.6. TA/TP Frequency
RF Optimization Tools Page 10 by Mazhar Kazi
It displays the TA/TP based coverage of all the cells having a particular frequency. This is very useful in determining Co and Adjacent Channel interferer.
TA Based Coverage of All Cells with Frequency “63”. TA Based Coverage of All Cells with Frequency “63” & “64”.
TA Based Coverage of All Cells with Frequency “63”, “64” & “65”.
1.7. Neighbor Display
Each Line represents a Neighbor. The color of the line is based on the neighbor stats are mentioned above.
