Wireless Lan Architecture - Korenix 5804 User Manual

Note: Only one of the LAN or WLAN interface can work. When connecting LAN and WLAN at the same
time, the LAN interface has higher priority than WLAN interface.

2.5 Wireless LAN Architecture

There are 2 typical WLAN architectures, one is infrastructure, and the other is Ad-Hoc mode.
Infrastructure mode: The 2 ends communicate via Access Point (AP). Access Point is the base station
which allows WLAN clients connect to. Each AP can accept several clients depend on the network
performance you plan to give. Usually up to 10-20 clients. The AP works like a hub, the connected clients
share the bandwidth it supports. For example: The AP supports 802.11g which means the available
Ad-Hoc mode: The 2 ends communicate with each other directly. In this architecture, there is no need
any access point. The JetPort and the host PC or 2 JetPorts can communicate with each other directly.
SSID:
SSID is short of the Service Set Identifier, it is referred to as a network name that identifies a wireless
network. The SSID is attached to the header of packets sent over the WLAN. The 2 ends of the
communication pairs should have the same SSID. This also can be viewed as one kind of password for
the WLAN end devices.
To configure the WLAN settings, no matter Infrastructure or Ad-Hoc mode. You should know the SSID of
the 2 ends first. In infrastructure mode, you should know the SSID of the access point and configure this
in the JetPort. In Ad-hoc mode, you should configure the same SSID for the JetPort and host PC or 2
JetPorts.
Configure the SSID of the Access Point (AP) by JetPort Commander when you first use the WLAN
interface or when you move to JetPort 5804 to the range of the other AP. Unplug the LAN port or power
reboot the device, then the WLAN interface can connect to the Access Point (AP) you assigned. It may
