Once the building is calibrated, changing some Wi-Fi access points will not affect the working system. Situm is pretty robust to antenna changes:

•  If you add new antennas, Situm will keep on working. Optionally, you may recalibrate to make the most of the new antennas (more accuracy), but this is not necessary.

•  If you remove some antennas, Situm will usually keep working (until you remove 50-70% of antennas of that area), no recalibration is required. This is, of course, provided if you have sufficient coverage in the first place.

•  If you change the place of some antennas, you may need to recalibrate only the affected areas. Optionally, we may disable those antennas in our backend, so they do not affect Situm (situation number 2) and no recalibration is required.
