About Wireless LAN

Wi-Fi®

Wi-Fi Certification assures tested and proven interoperability by the Wi-Fi Alliance, a group certifying interoperability among wireless LAN devices.

IEEE 802.11b

This is one wireless LAN standard set by the 802 working group that establishes LAN technology standards at the IEEE (Institute of Electrical and Electronics Engineers) of the United States. It uses the

2.4GHz band usable freely without a radio frequency license (ISM band), enabling communications at a maximum speed of 11 Mbps.

The value indicated above is the maximum theoretical value for the wireless LAN standard, and does not indicate the actual data transfer rate.

IEEE 802.11g

This is another wireless LAN standard set by the 802 working group that establishes LAN technology standards at the IEEE (Institute of Electrical and Electronics Engineers) of the United States, and is compatible with IEEE 802.11b. It also uses the 2.4 GHz band, but enables communications at a maximum speed of 54 Mbps.

The value indicated above is the maximum theoretical value for the wireless LAN standard, and does not indicate the actual data transfer rate.

Infrastructure Communications

“Infrastructure Communications” refers to networks using wireless LAN access points.

This function can be used to connect to the Internet or a wired LAN via a wireless LAN access point. Wireless LAN access points include wireless broadband routers.

Ad-hoc Communications

Signaltransferthroughwirelessinterconnectionofcomputersisreferred to as “ad hoc communications”. With such ad hoc communications there is no connection to the Internet. Ad hoc communications are suited for establishing simple temporary networks.

Network Names (SSID: Security Set Identifier)

When forming wireless LAN networks, groups are formed to prevent interference, data theft, etc. This grouping is done by “SSID” or “Security Set Identifiers”. For further security, a WEP key is set and signal transfer is not possible unless the SSID and WEP key match.

WEP Key (Network Key)

This is key information used for encrypting data when conducting data transfer. On the S-302, the same WEP key is used for data encryption and decryption, so the same WEP key must be set on both devices in order for communications to be established between them.

WPA (Wi-Fi Protected Access)

 

 

Getting

 

This is a security standard established by the Wi-Fi Alliance. In addition

 

 

 

to the conventional SSID (network name) and WEP key (network key),

 

Started

it also uses a user identification function and encrypting protocol for

 

stronger security.

 

WPA2 (Wi-Fi Protected Access 2)

 

 

Connections

This is a new version of the WPA established by the Wi-Fi Alliance,

 

 

compatible with more secure AES encryption.

 

 

WPA-PSK/WPA2-PSK (Pre-shared Key)

 

 

Setup

This is a simple authentication system for mutual authentication when

 

 

 

a preset character string matches on the wireless LAN access point

 

Playback

and client.

 

 

 

Passphrase

 

 

Remote

This refers to the code key used forWPA-PSK/WPA2-PSK authentication,

 

a WPA authentication method.

 

TKIP (Temporal Key Integrity Protocol)

 

 

Control

 

 

This is a network key used for WPA. The encryption algorithm is RC4,

 

 

 

Information

the same as for WEP, but the security level is increased by changing

 

 

 

the network key used for encryption for each packet.

 

 

AES (Advanced Encryption Standard)

 

 

 

This is a next generation standard encryption method replacing the

 

Troubleshooting

 

 

current DES and 3DES, and because of its high security it is expected to

 

 

be applied widely to wireless LANs in the future. It uses the “Rijndael”

 

 

algorithm developed by two Belgian cryptographers to divide the data

 

 

into blocks of fixed lengths and encrypt each block. It supports data

 

 

lengths of 128, 192 and 256 bits and key lengths of 128, 192 and 256

 

 

 

 

bits as well, offering extremely high encryption security.
