Configuring Gigaset PC Card 108

Operating mode

ì Enter the Network Mode for the network environment:

– Infrastructure:

There are wireless (WLAN) and wired (LAN) PCs in the network environment.

The connection between WLAN and LAN is set up via an Access Point.

– Ad Hoc:

The network environment does not have a fixed structure, but is set up between

the available wireless network adapters as and when required. No Access Point is

required.

The default operating mode is Infrastructure.

You will find a detailed description of the operating modes in Chapter "Wireless LAN

Basics" on page 4.

Transmission rate

Transmission rate is the term used to describe the data volume sent per second between

two PCs. The transmission rate is measured in Mbps (Megabits per second).

ì Select the Transmission Rate:

–With the Auto setting, the network adapter checks the connection quality for

each data transmission and automatically selects the most suitable transmission

rate. The only default transmission rate setting is Auto.

– You can specify a different rate using the pop-up window. By doing this you are

specifying the maximum value for transmission rates. If you select 24 Mbps for

example, the network adapter tries to use this rate for every transmission. The

setting prevents a faster transmission rate. If the connection quality falls, the net-

work adapter will select the next lower transmission rate.

Please remember:

In Ad Hoc mode, the device will work in 802.11b transmission mode, i.e. with a max-

imum transmission rate of 11 Mbps. You should therefore set up an Access Point so

that you can transfer large volumes of data.

Note:

In wireless networks, the maximum achievable Transmission Rate depends on the

signal strength and link quality of the connected network adapters. The Signal

Strength in turn depends on other factors; for example it falls rapidly as the distance

between the network adapters increases.

The setting for Auto Transmission Rate is particularly recommended where the oper-

ating conditions fluctuate.
