Figure 7.2: Elevation profile of the Kumpuvaara site area
Figure 7.2 shows the elevation profile of the measurement area. Elevation data for the
area was extracted from NASA’s SRTM3 database [28] and expanded in visual form by
using Matlab. The resolution of data-grid is approximately 90 m (3 arc seconds). The
data set was linearly interpolated to fill in the missing points in the display.
The measurement unit was placed inside a measurement vehicle. A 1 Gigabyte file lo-
cated in the remote FTP server was to be downloaded using the USB modem while be-
ing attached with the test network. Radio parameters during this active connection when
the file was being downloaded were measured and recorded by Nemo Outdoor. Meas-
urement routes were chosen such that most of the peripheries for both sites were meas-
ured. The measurements were however constrained by the roads.
