<strong>Evaluation</strong> <strong>of</strong> <strong>Rural</strong> <strong>Dominant</strong> <strong>Path</strong> <strong>Model</strong><br />
General Remarks<br />
• All computations were accomplished on a standard<br />
PC AMD Athlon 3200+ with 2 GB <strong>of</strong> RAM.<br />
• ProMan Version 10.0 with default settings was used<br />
for the compuations.<br />
• Two different sets <strong>of</strong> path loss exponents were used<br />
depending on the transmitter height:<br />
Section<br />
High<br />
Tx<br />

Tx<br />
LOS before breakpoint 2.3<br />

LOS after breakpoint 3.6 3.6<br />
NLOS before breakpoint 2.6 2.8<br />
NLOS after breakpoint 4.0 4.0<br />
