Positioning Engine tracks location of multiple clients simultaneously and returns position relative to the
floor plan. The Positioning Engine can be configured to track associated users (active clients) or all
users.
•
Associated User. An associated user is an authenticated client. An associated user joins the SSID
provided by the AP by simply associating to the open or protected SSID. Positioning Engine can
track location for every associated client up to the ExtremeCloud Appliance model limit of
associated clients.
•
Un-Associated User. An unassociated user is a client that is not authenticated but is in the
designated area. Positioning Engine can track these clients.
Note
AP models AP76xx and AP8xxx support heat maps for Location Readiness but do not
support Foot Traffic heat maps. Use ExtremeLocation integration for client tracking support
with these APs.

Position Aware Deployment
Deploying APs for location tracking requires additional consideration above the standard AP
deployment guidelines for coverage and capacity. The following are best practices for AP deployment:
•
Minimum Received RSS. No fewer than three APs should be detecting and reporting the RSS of any
client station. Only RSS readings stronger than -75 dBm are used by the Location Engine.
•
Use the same AP model for the entire floor plan.
•
Design your floor plan with the APs installed at the corners of the floor plan, along the perimeter of
the location area. (An area is considered a closed polygon.) Do not cluster APs in the center of the
location area. The following illustration shows a recommended AP placement.
Figure 3: Recommended AP Placement
•
The maximum distance between APs depends on environmental factors such as the presence of
walls and structures, but as rule of thumb, in a location-aware deployment, place the APs 10 to 20
meters apart.
•
Install APs at the same height on the wall, and do not install APs behind walls or ceilings.
•
Install APs away from metal structures like poles or racks, because metal can affect the radiated
pattern.
