Operating Instructions, Release 08/2007, C79000-G8976-C221-02
Outdoor AP mode (only in access point mode) / Outdoor Client mode (only for clients or access point
in client mode)
The device can be operated either in the indoor or outdoor mode. In indoor mode, all the
country-dependent permitted channels and transmit power settings are available for
operation in a building. In outdoor mode, the selection of country-dependent channels and
the transmit power for operation are restricted for outdoor use. You enable this mode by
selecting "Outdoor AP mode" or "Outdoor Client mode".
Channel Selection
On clients or access points in client mode, you can only set a channel in ad hod mode.
For access points, you have the following options: Select the "Auto Channel Select" check
box if you want the access point to search for a free channel itself. If you want to specify a
specific channel, make sure that "Auto Channel Select" is not selected. You can specify a
suitable channel in the "Radio Channel" drop-down list box.
IEEE 802.11h transmission:
If you have selected the 802.11h protocol for transmission in access point mode and "Auto
Channel Select" is not selected, the "Alt. radio channel" input box is displayed below
"Radio channel". Here, you can select the alternative channel in case signals of a primary
user are found on the main channel.
Make sure that the alternative channel is not being used by other access points.
In the IEEE 802.11h transmission mode, it is not practical to select the WDS mode. In WDS
mode, all access points must use the same channel. If a signal from a primary user is
detected by an access point, the channel is changed automatically and the existing
connection is then terminated.
MAC address of the client (only for clients or access points in client mode)
A MAC address must be specified for the devices connected to the Ethernet port of the client
before it can be reached. This MAC address is used by the client for wireless communication
with the access point. This can be done automatically by the client adopting the MAC
address of the first frame that it receives over the Ethernet interface. If this is required, "Auto
find Adopt MAC" must be selected.
As long as the client is waiting for an Ethernet frame, it registers with the access point using
its own MAC address. As soon as the first Ethernet frame is received, the client deregisters
from the access point and immediately registers again with the MAC address from the
Ethernet frame. If there is now a link-down on the Ethernet port, the client deregisters from
the access point and registers again with its own MAC address.
If several devices are connected to the client, you should not select this setting.
You also have the option of specifying the MAC address of the connected device manually.
To use this option, select "Set 'Adopt MAC' manually" and enter the MAC address of the
device connected to the client in the "Adopt MAC" input box.
To be able to address an entire network of devices downstream from the client, "Adopt own
MAC" must be selected. In this case, only layer 3 connections (TCP/IP) are possible. This is,
however, not possible with the SCALANCE W744-1PRO and SCALANCE W744-1.
If up to eight MAC addresses need to be served downstream from the client, the "Layer 2
Tunneling" setting must be selected for the client.
