Configure AeroScout Mobile Unit from AeroScout Engine
Follow the steps below to configure an AeroScout Mobile Unit from the AeroScout
Engine:
1. Enable Aeroscout on the controller.
2. Open the Aeroscout Engine.
3. Load the Floor Map on the Engine.
4. Add the APs on the Aeroscout Engine.
5. In the Configuration->system parameters->Access Points, check the “Enable
mobile-unit location with access Points” checkbox.
6. To start the Mobile Unit Positioning option on the AeroScout engine, select ‘Start
MU positioning’ from the Actions menu.
AeroScout Compounded Report
For better performance, several MU reports can be combined within a fixed
pre-defined period in Compounded Reports. Meru’s system combines a maximum of
18 MU reports in one Compounded Report. The number of Mobile Unit reports inside
the Compounded Report varies as per the Compounded Message Timeout configured
on the Aeroscout Integration Tool. The ‘Compounded Message timeout’ is configured
on the Aeroscout Integration tool under ‘Set Configuration’.
Dilution Timeout
In certain scenarios, the Mobile Unit traffic may be high, and the time resolution
needed for location is much lower than the data rate of most Mobile Units. If every
AP starts reporting every Wi-Fi frame to the Aeroscout Engine, it will create unnec-
essary data overhead on the network, and provide a real-time location in a level
much higher than required.
To help the AP dilute messages from each Mobile Unit, the Aeroscout protocol
provides the following two parameters:
