Security - Nortel 120 Using Manual

Super G—The Atheros proprietary Super G performance enhancements
are supported by the access point. These enhancements include bursting,
compression, fast frames, and dynamic turbo. Maximum throughput ranges
between 40 to 60 Mb/s for connections to Atheros-compatible clients.
(Default: Disabled)
Preamble—Sets the length of the signal preamble that is used at the start of
a data transmission. (Default: Short)

Security

The access point is configured by default as an open system, which
broadcasts a beacon signal including the configured SSID. Wireless clients
with an SSID setting of any can read the SSID from the beacon and
automatically set their SSID to allow immediate connection to the nearest
access point.
To improve wireless network security, you have to implement two main
functions:
•
•
For a more secure network, the access point can implement one or a
combination of the following security mechanisms:
•
•
•
•
Both WEP and WPA security settings are configurable separately for each
virtual access point (VAP) interface. MAC address filtering, and RADIUS
server settings are global and apply to all VAP interfaces.

Long: Sets the preamble to long (192 microseconds). Using a long
preamble ensures the access point can support all 802.11b and 802.11g
clients.
Short or Long: Sets the preamble according to the capability of clients
that are currently associated. Uses a short preamble (96 microseconds)
if all associated clients can support it, otherwise a long preamble is
used. The access point can increase data throughput when using a
short preamble, but only uses a short preamble if it determines that
all associated clients support it.
Authentication: It must be verified that clients attempting to connect to
the network are authorized users.
Traffic Encryption: Data passing between the access point and clients
must be protected from interception and eavesdropping.
