Tool for Drive Test and Benchmarking: KML Generator

September 4, 2019.

Engineering services and telecommunications operators running Drive Test measurements, Network optimizations, Walk test and Service quality analysis can now take profit of the ability of PROMAX analyzers to perform signal coverage analysis of television broadcasting centers.

Now, with the KML Generator utility, there are much more options to generate 3D signal coverage maps, Microsoft Excel spreadsheets and CSV files to export them to databases or third party applications.

A signal coverage analysis generated with KML Generator

In a drive test analysis a technician goes all over the area covered by an emitter, gathering measurements of its signal reception and storing their geographical location via GPS. Data is studied or/and depicted on a map to certify the proper signal reception, locate shaded areas, illegal broadcasters, etc.

By using KML Generator it is possible to convert the data of a drive test analysis generated using a PROMAX analyzer to a Google Earth compliant format. This application allows displaying the measurements over a 3D map and visually locating the points having a poor reception quality.

Display a signal coverage analysis in Microsoft Excel

By using KML Generator it is also possible to directly create Microsoft Excel files in order to analyze the data captured during the drive test with all the benefits of a spreadsheet.

KML Generator can generate a graph comparing the measurement of all the channels, making easier for technicians to locate the points with better and worse reception quality.

It is available the option to automatically format the worksheets cells so they become print-friendly and the document can be used as a measurement report. Just one click away!

Display a signal coverage analysis in CSV format

CSV (Comma-Separated Values) is a raw data universal interchange format. CSV files are plain, unformatted text files. Most office and data base software can deal with CSV.

Because of KML Generator can export the drive test data to CSV, the raw data can be imported and adapted to any analysis software, database, etc.
