Content Access Control
The Prestige can control access privileges to website and services through Content Access
Control (CAC). Content Access Control can be defined as the ability for a LAN administrator
to control a LAN user's Internet access privileges. The administrator can create a login name
and password for each user on the network. Each user must log into the system before they can
gain access to the Internet. Each account will have specific access restrictions.
Anti-Virus Packet Scan
With the anti-virus packet scan, your Prestige detects and removes viruses in network packets
(SMTP, POP3, HTTP and FTP). This prevents viruses from infecting computer(s) on the
network. You can set the Prestige to log and warn you of any viruses detected. You can also
perform online update of the packet scan on the Prestige.
IEEE 802.11g Wireless LAN
IEEE 802.11g is fully compatible with the IEEE 802.11b standard. This means an IEEE
802.11b radio card can interface directly with an IEEE 802.11g access point (and vice versa) at
11 Mbps or lower depending on range. IEEE 802.11g has several intermediate rate steps
between the maximum and minimum data rates. The IEEE 802.11g data rate and modulation
are as follows:

Note: The Prestige may be prone to RF (Radio Frequency) interference from
other 2.4 GHz devices such as microwave ovens, wireless phones, Bluetooth
enabled devices, and other wireless LANs.
External Antenna
The Prestige is equipped with an antenna connector and comes with a detachable 5dBi antenna
to provide clear radio signal between the wireless stations and the access points.
Note: Under the CE regulations, when using a 5dBi or higher gain antenna
with the Prestige, the maximum antenna power output must be less or equal
to 20dBm. Refer to the support note for more information.
