When we did the sensitivity/specificity experiment again, we also used the MoteMate iPhone app and the motes that wrote to flash. We used channel 14 for these motes, as opposed to channel 25 for the other motes.
Anchor 46 was in the room and Anchor 42 was at the nurse’s station. The flash data from Anchor 42 was not available for analysis.
The data in this plot shows that this experiment did not go as planned. At the Nurse’s Station – Anchor 42 should have a Higher RSSI than Anchor 46. Anchors 46 and 42 were about equal for the Nurse’s Station, and this should not be the case. The same happened in Room A. I’m not sure what happened here. The CDF’s also show this problem.
