4 Configuring WE865-DUAL

In order to better understand how to configure WE865-DUAL wifi module it is very important to read

the introduction in typical wireless networks configurations and devices involved.

4.1 Typical IEEE 802.11 network scenario

A typical wireless network is mainly made up of clients and Access Points (AP).

Clients (such as PCs, PDAs, laptops, VOIP phones, etc.) connect to an AP. The AP usually connects

to a wired network and can relay data between wireless devices and wired devices.

Connection between clients and the AP can be secured enabling different encryption modes like WEP,

WPA and WPA2 (IEEE 802.11i). Enterprise wireless LANs usually use RADIUS authentication servers

along with encryption in order to have as strong as possible WiFi connections. When WPA/WPA2

encryption is used, we talk about WPA-Personal in non Enterprise environments, and WPA-Enterprise

otherwise. For further information about WPA and WPA2 (IEEE 802.11i) see 8.1 paragraph.
