Managed RF Optimization

Automatic channel selection ensures that the devices always operate with the best available channels. Managed RF Optimization allows you to instruct an AP to find the appropriate channel with a simple press of a button. A prerequisite for this is the Inter Access Point Protocol (IAPP), which allows the APs to communicate with one another.

APs use the IAPP protocol to communicate and pass information about the handovers of associated WLAN clients which are roaming. APs regularly send out multicast announcements to inform the devices about the BSSIDs and IP addresses of the other APs. A roaming WLAN client informs a new AP about its former AP. The AP uses the information supplied by the IAPP protocol to inform the former AP to remove the WLAN client from its list of associated clients.

You can initiate channel selection either manually or you can let the devices perform it automatically.

After receiving the command to execute automatic channel selection, each AP performs the following actions:

The relevant WLAN is disabled.
The AP sets its priority based on the IAPP table.
The AP waits for a specified period of time (priority * waiting time (10 seconds)).
The AP reactivates the relevant WLAN.
The AP performs an automatic channel selection.

Each AP in the same network searches for the optimal channel in a particular order. This ensures that not all devices commence their channel selection at the same time.
