Google Earth UtilityBy Mazhar Kazi

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.

TA/TP Bin Sample Per. Color

>= 3 AND <5 Green >= 5 AND <10 Yellow >= 10 Red

1.1. TA/TP Bin’s Information BalloonTA/TP Bin’s Information Balloon displays the information related to a particular TA/TP bin. For e.g. Traffic

carried / Percentage sample in this particular Bin, the Distance of the bin from the site.

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.
