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 660HW 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 660HW, the maximum antenna power output must be less or equal to
20dBm. Refer to the support note for more information.
Wireless LAN MAC Address Filtering
Your Prestige can check the MAC addresses of wireless stations against a list of allowed or
denied MAC addresses.

WEP Encryption

WEP (Wired Equivalent Privacy) encrypts data frames before transmitting over the wireless
network to help keep network communications private.
Wi-Fi Protected Access
Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i security specification draft.
Key differences between WPA and WEP are user authentication and improved data
encryption.
