Configuring the Wireless AP

Configuring Wireless AP Settings

SCALANCE WLC711

User Guide, V8.11, 07/2012, C79000-G8976-C260-03 3-33

Antenna Selection Click the antenna, or antenna combination, you want to configure

on this radio.

Note: When you configure the Wireless 802.11n AP to use

specific antennas, the transmission power is recalculated; the

Current Tx Power Level value for the radio is automatically

adjusted to reflect the recent antenna configuration. It takes

approximately 30 seconds for the change to the Current Tx

Power Level value to be reflected in the SCALANCE W Wireless

Assistant. Also, the radio is reset which may cause client

connections on this radio to be lost.

Advanced Dialog - Base Settings

DTIM period Type the desired DTIM (Delivery Traffic Indication Message)

period — the number of beacon intervals between two DTIM

beacons. To ensure the best client power savings, use a large

number. Use a small number to minimize broadcast and multicast

delay. The default value is 5.

Beacon Period Type the desired time, in milliseconds, between beacon

transmissions. The default value is 100 milliseconds.

RTS/CTS Threshold Type the packet size threshold, in bytes, above which the packet

will be preceded by an RTS/CTS (Request to Send/Clear to Send)

handshake. The default value is 2346, which means all packets

are sent without RTS/CTS. Reduce this value only if necessary.

Frag. Threshold Type the fragment size threshold, in bytes, above which the

packets will be fragmented by the Wireless AP prior to

transmission. The default value is 2346, which means all packets

are sent unfragmented. Reduce this value only if necessary.

Max % of non-unicast traffic per

Beacon period

Enter the maximum percentage of time that the AP will transmit

non-unicast packets (broadcast and multicast traffic) for each

configured Beacon Period. For each non-unicast packet

transmitted, the system calculates the airtime used by each

packet and drops all packets that exceed the configured maximum

percentage. By restricting non-unicast traffic, you limit the impact

of broadcasts and multicasts on overall system performance.

Maximum Distance

Enter a value from 100 to 15,000 meters that identifies the

maximum link distance between APs that participate in a WDS.

This value ensures that the acknowledgement of communication

between APs does not exceed the timeout value predefined by the

802.11 standard.

The default value is 100 meters. If the link

distance between APs is greater than 100 meters, configure the

maximum distance up to 15,000 meters so that the software

increases the timeout value proportionally with the distance

between APs.

Do not change the default setting for the radio that provides

service to 802.11 clients only.
