Data collected
A huge amount of raw measurement data needed to be placed in a structured MySQL database. Therefore, we developed an interface, which will allow for automatic filtering, consolidating and enriching the data during the import. Filtering approach was to get any information of measured signals without any capabilities of creating interferences out of the database, as well getting in only the strongest signals for each frequency in correlation with the angle of arrival (angle on which measurements were taken). Consolidation was made in terms of automatically converting dBµV/m into more convenient dBm during the import phase, as consolidating the minor location variations caused by the GPS reception fluctuation. Interface we created enriches measurement data with information of Location name, region, and antenna polarization. Enrichment info is provided manually and the automatically fed into the data structure.
