SCALANCE W770/W730 to IEEE 802.11n Web Based Management

264 Configuration Manual, 11/2014, C79000-G8976-C323-03

Access point mode

You are using an access point in access point mode.

Description

The table has the following columns:

●

Radio

Specifies the WLAN interface to which the settings relate.

●

Enable iPCF

Enable or disable iPCF mode. For PNIO communication, we recommend that you enable

the iPCF mode. By enabling iPCF, the data rates provided by the access point are

adapted. We strongly recommend that you retain the default setting for the data rates

(802.11 a/b/g = 12 Mbps and 802.11n = MCS 2).

●

PNIO Support

Enable or disable optimized support of PNIO.

●

iPCF Cycle Time [ms]

Select the required cycle time from the drop-down list.

The following points need to be taken into account when setting the cycle time. Otherwise

it may not be possible to establish stable communication.

– There is only one access point in the system; in other words, the clients move only in

one wireless cell. In this case, update times >= 16 ms are supported.

– There are several access points in the system that communicate over different

channels. The clients roam between the access points. In this case, select update

times >= 32 ms.

In addition to the guide values shown above, remember that the shortest cycle time to be

set is calculated according to the formula "2 ms * max. number of nodes".

●

Scanning Mode

The selected setting affects the scanning of the logged-on clients.

The following settings are available:

–

All Channels

The client scans all permitted channels and selects the access point with the best

signal strength and connects to it.
