SCALANCE W760/W720 to IEEE 802.11n Web Based Management
Configuration Manual, 11/2014, C79000-G8976-C350-03

Description

2.1

Network structures

The following article deals with the setting up of various network structures using access

points and clients. A client is also an access point in client mode.

Standalone configuration with access point

This configuration does not require a server and the access point does not have a

connection to a wired Ethernet. Within its transmission range, the access point forwards data

from one WLAN node to another.
The wireless network has a unique name. All the devices exchanging data within this

network must be configured with this name.

Figure 2-1

Standalone configuration of an access point. The gray area symbolizes the wireless

range of the access point.
