About Wireless
Security
Since communication via the wireless LAN
function is established by radio waves, the
wireless signal may be susceptible to
interception. To decrease this danger, the
LocationFree TV supports various security
functions. Be sure to correctly configure the
security settings in accordance with your
intended purpose and network environment.
Wireless LAN security function of the
LocationFree TV
• No encryption
Because raw data is transmitted, there is a
danger of interception.
This setting is not available for wireless LAN
communication between the Base Station and
the Monitor.
• WEP
WEP is the wireless LAN security technology
specified by IEEE802.11. It applies encryption
to communications. There are two types of
encryption key length; 64-bit key and 128-bit
key. The 128-bit encryption key assures a
higher security level. A decryption technique
exists, however, so using the same encryption
key for an extended period of time is not
recommended.
• WPA-PSK with TKIP encryption
WPA is a security technology developed to
correct for the deficiencies of WEP. The
LocationFree TV utilizes WPA together with
TKIP encryption. WPA-PSK with TKIP
encryption assures the highest security level
among the technologies supported by the
LocationFree TV.
Security settings of the LocationFree TV
• The security for wireless LAN communication
between the Base Station and the Monitor is set
to WEP as the factory default. To increase the
security level, switch to WPA-PSK. Note,
however, that the communication stability may
differ depending on which technology you use,
WEP or WPA-PSK.
• When connecting the Monitor to a wireless
LAN environment other than that for
communication with the Base Station, the
Monitor should be configured in accordance
with the security setting of the wireless LAN
environment. For settings information, contact
the network administrator.
