Radio Frequency The AP automatically configures most radio parameters. Exercise extreme caution Parameters 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:

1Select ConfigurationRF. The RF Setup page displays.

2Enter 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.

3Enter the Max Retries (data) value. The value represents the maximum allowed retries before the AP aborts a single transmission attempt. The default is 15.

4Enter the Max Retries (voice) value. The value represents the maximum allowed retries before the AP aborts a single transmission attempt. The default is 15.

5Enter 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.

6Enter the time between beacons in milliseconds for Beacon Interval. The default is 100 milliseconds.

7Select 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.

8Enter 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.

9Select values for Rate Control at the three transmission rates. The default values are:

11 Mbps - Optional

5.5 Mbps - Optional

2 Mbps - Required

1 Mbps - Required
