Reliability and validity test 

Reliability of the measurements was tested and elaborated in Section 7.1.3.3  by per-

forming a multiple run test on the same measurement route. The parameter tested was 

RSRP. Graphical and statistical analyses shown in the section indicate that for a particu-

lar measurement route, measurement data was found to be reliable and statistically con-

sistent  (refer to Figure 7.11  and  Table  7.6). The setup of test network with single test 

UE ensured that the interference from other UEs was negligible and the data observed 

was consistent. Thus, the data can be considered reliable. 

The analyses can also be called valid as it adheres to the theoretical and empirical mod-

els. The downlink throughput has stayed within the Shannon and Rayleigh capacity lim-

itations. The maximum throughput observed was about 28 Mbps below the theoretical 

maximum. The theoretical capacity however does not include the control channel traffic 

and other radio environment related losses which could account for some of the lost 28 

Mbps. The cell radius as calculated from the link budget was 29.3 km which is approx-

imately equal to the maximum detected set range observed i.e. 30.2 km. Performance of 

different bands was also  calculated with analysis of SNR against the throughput and 

both bands performed 90% of the sample duration.  The minor deviations of the ob-

served values from the theoretical limits and the performance  show that the measured 

data and the conclusions drawn are valid.
