Getting To Know Your Prestige 1-3
IEEE 802.11
g
DATA RATE (MBPS) MODULATION
1 DBPSK (Differential Binary Phase Shift Keyed)
2
DQPSK (Differential Quadrature Phase Shift Keying
)
5.5 / 11 CCK (Complementary Code Keying)
6/9/12/18/24/36/48/54 OFDM (Orthogonal Frequency Division Multiplexing)
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
2
The Prestige is equipped with an antenna connector and comes with a detachable 5dBi antenna to
provide clear radio signal between the wireless stations.
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.
Traffic Redirect
Traffic redirect forwards WAN traffic to a backup gateway when the Prestige cannot connect to the
Internet, thus acting as an auxiliary if your regular WAN connection fails.
Bandwidth Management
Bandwidth management allows you to allocate network resources according to defined policies. This
policy-based bandwidth allocation helps your network to better handle real-time applications such as
Voice-over-IP (VoIP).
Universal Plug and Play (UPnP)
Using the standard TCP/IP protocol, the Prestige and other UPnP enabled devices can dynamically
join a network, obtain an IP address and convey its capabilities to other devices on the network.
2
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.
