I'm testing the Meraki positioning provided by Meraki's Scanning API.
I positioned 4 Meraki (2 MR33, 1 MR32 and 1 MR42) in a floorplan of 80 square meters, as can be seen in the attached map image.
I noticed some strange behavior.
Floorplan
1) The data sent by the 4 meraki are not synchronized, each meraki sends its detections every minute and a half more or less, but not at the same time, they should not work together to estimate the most accurate position? Is there a way to set something to improve sync?
2) The coordinates provided are very far from the actual data. We did a test by placing a smartphone connected to the Meraki network in coordinates (9.5.7.5) and left it there for 15 minutes to see the accuracy of the positioning with the APIs. The results can be seen in the figure below. (B = ApMacAddress, E = Time, R = X, S = Y, T = unc)
Surveys
With this equipment is there an optimal way to place them?
