An encryption technology used for Wireless LAN (below). To protect security during
information transmissions, communication can only occur when the same network key
(
) is registered to both parties involved in the communication.
Wireless LAN
A LAN (
) that conducts wireless communications using radio waves. Data is sent
and received using common wireless frequencies. Because a LAN cable is not required, the
computer can be located some distance from the Access Point (
). ESS-ID
) or WEP (above) can be used to protect security during information
transmissions.

WPA
– Wi-Fi Protected Access
WPA compensates for the weaknesses of WEP (above), to further increase security. The
network key (
