Key terms
SSID (Service Set Identifier)
It is a name to identify the particular wireless LAN. So, every single station should
have the same SSID to communicate in the network. In the case of infrastructure
mode, you have to set the same SSID with the AP to CSW-H85K. Otherwise, it will
not communicate at all. The maximum length of this parameter is 31 bytes and the
default is
“
sollae
”
.
Channel
Wireless LAN stations communicate through the ISM (Industrial, Scientific, and
Medical) band which has the range of frequencies around 2.4GHz. IEEE 802.11
specification divides this band into 14 channels in every 5MHz. If you install more
than one wireless network in the same area, the channels should be apart more than
4 channels to avoid interferences.
2.1.5
Authentication and Security
Authentication
A wireless LAN station should get authentication from the AP in the infrastructure
network. There are two methods for the authentication and those are Open System
and Shared Key.
WEP (Wired Equivalent Privacy)
The WEP is a secure protocol for wireless LAN. You need to set 64-bit or 128-bit key.
You can use both hexadecimal and ASCII code for this.
WPA (Wi-Fi Protected Access)
WPA is a security standard for users of devices equipped with Wi-Fi wireless
connection. It is an improvement on and is expected to replace the original Wi-Fi
security standard, Wired Equivalent Privacy (WEP). There are two modes about the
user authentication in WPA security. One is Enterprise which has an authentication
server and the other is PSK (Pre-Shared Key) which does not have any servers.
WPA2
To final security of Wireless LAN, IEEE 802.11i which is a standard about Wireless LAN
has suggested the Counter Mode with Cipher Block Changing Message
Authentication Code Protocol (CCMP) for replacing the TKIP. CCMP uses Advanced
Encryption Standard (AES). WPA 2 adopts AES. WPA 2 has also both Enterprise and
PSK mode.
