Radio Frequency
Parameters
The AP automatically configures most radio parameters. Exercise extreme caution
when you adjust radio parameters for the AP since these parameters affect system
operations. Options in the RF Configuration window fine-tune the radio and
WLAP functions.

To configure the radio parameters:
1 Select Configuration
→RF. The RF Setup page displays.
2 Enter a value (in packets) for BC/MC QueuMax.This value determines the amount
of memory allocated for the queue used in the AP to temporarily hold
broadcast/multicast messages. The packets corresponds to the maximum-size
Ethernet packets. The default is 10.
broadcast/multicast messages. The packets corresponds to the maximum-size
Ethernet packets. The default is 10.
3 Enter the Max Retries (data) value. The value represents the maximum allowed
retries before the AP aborts a single transmission attempt. The default is 15.
4 Enter the Max Retries (voice) value. The value represents the maximum allowed
retries before the AP aborts a single transmission attempt. The default is 15.
5 Enter the Multicast Mask (data) and (voice) values.
AirConnect supports broadcast download protocols for any wireless client
(typically Point-of-Sale terminals) requiring the expedited download of a new
operating image over the network instead of using a local nonvolatile drive.

All multicast downstream data packets that match the top 32 bits of the multicast
mask are forwarded immediately instead of being queued for transmission at the
next DTIM interval.

next DTIM interval.
6 Enter the time between beacons in milliseconds for Beacon Interval. The default is
100 milliseconds.
7 Select Enable or Disable for Accept Broadcast Wireless LAN Service Area.
This feature allows the AP to respond to any station sending probe packets with
the industry-standard broadcast WSA. When Enabled, this feature allows
industry-standard devices interoperability. The AP probe response includes the
WSA_ID and information about the network. By default, this feature is Disabled
and the AP responds only to stations that know the WSA_ID. This helps preserve
network authentication security.

8 Enter a value in minutes for the Wireless Client Inactivity Timeout.
This value specifies the number of minutes the AP allows for wireless client
inactivity. An AirConnect AP recognizes wireless client activity through data packet
transmission and reception, and through scanning. AirConnect wireless clients
conduct active scanning. Other industry-standard wireless clients might conduct
passive scans and an AirConnect AP could classify them as inactive.
