I did two experiments in the hospital to test the distinction between near and far from the bed in the hospital. For near the bed, I stood in two positions – near the head of the bed and near the foot of the bed. For far from, I stood in the middle of the room and just in the doorway. One experiment used 2 F antennas (near the head and near the foot) and the other one used a whip antenna.
Here are the results:
From this graph, we see that there is almost no distinction between the different locations using 2 F antennas.
From this graph, we see that near the head of the bed gives higher results than the other positions, but the distinction is still not that great.
From this graph, we see that there is almost no distinction between the different positions. But, we do see that position 4 (in the doorway) lags behind the rest of the positions, which is good.
Looking at this data, I think we’ll have to redo the experiments after we find out what could have caused this. The experiments we did in the lab showed much better distinction between locations.
