Wearable Smart Radio Field Testing Results: Doodle Labs Field Tests

Doodle Labs Field Tests

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.
