Wi-Fi
®
Wi-Fi Certification assures tested and proven interoperability by the Wi-Fi
Alliance, a group certifying interoperability among wireless LAN devices.
WPA (Wi-Fi Protected Access)
This is a security standard established by the Wi-Fi Alliance. In addition to
the conventional SSID (network name) and WEP key (network key), it also
uses a user identification function and encrypting protocol for stronger
security.
WPA2 (Wi-Fi Protected Access 2)
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)
This is a simple authentication system for mutual authentication when a
preset character string matches on the wireless LAN access point and
client.
WPS (Wi-Fi Protected Setup)
This is a standard drawn up by the Wi-Fi Alliance to ease the task of
setting up wireless LAN connections and configuring security. There are
two methods: push-button and PIN (Personal Identification Number) code.
Network Names (SSID: Security Set Identifier)
When forming wireless LAN networks, groups are formed to prevent
interference, data theft, etc. These groups are based on “SSID (network
names)”. For enhanced security, a WEP key is set so that communication
is unavailable unless both the “SSID” and the WEP key match. This is
suitable for temporarily constructing a simplified network.
Modem
Device that connects to your broadband internet provider, and is very
often supplied with the service. A type that is integrated with a router is
also often available.
