When using RSSI-based location determination at a site with only one floor the coverage area of each
of the receivers will roughly determine the location of the wireless device.
Previously location determination was done by adding LF beacons to the system. When only using LF
beacons for the same layout with only one floor, about eight LF beacons would be required to
determine the location.
Figure 81. Location determination using LF beacons
By combining LF beacons with receivers using the RSSI-based location determination functionality,
fewer LF beacons are required to cover the floor. In the example, LF beacons would only have to be
installed near the staircases. This will also allow for a more accurate location determination in a multi
story building.
