Numerous performance tests were conducted
on a long-straight road with both radios at shoulder height. A picture of the
test location is shown in Fig. 4. The measurements were limited to the 900 meter
range due to the road blockage. However, do note the increase in throughput
at higher frequencies due to smaller Fresnel zone obstruction. This would mean
longer range if it was possible to go further out.
