Radio Interface
Super Mode – 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 Mbps for connections to Atheros-compatible clients.
(Default:
Disabled)
Radio Channel – The radio channel that the access point uses to communicate
with wireless clients. When multiple access points are deployed in the same area,
set the channel on neighboring access points at least five channels apart to avoid
interference with each other. For example, in the United States you can deploy up
to three access points in the same area (e.g., channels 1, 6, 11). Also note that
the channel for wireless clients is automatically set to the same as that used by
the access point to which it is linked. (Range: 1-11; Default: 1)
Auto Channel Select – Enables the access point to automatically select an
unoccupied radio channel. (Default: Enabled)
Maximum Transmit Data Rate – The maximum data rate at which the
access point transmits unicast packets on the wireless interface. The
maximum transmission distance is affected by the data rate. The lower the
data rate, the longer the transmission distance. (Default: 54 Mbps)
Preamble Length – Sets the length of the signal preamble that is used at
the start of a data transmission. (Default: Long)
Short: Sets the preamble to short (96 microseconds). Using a short
preamble can increase data throughput.
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.
Auto: 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 will only use a short
preamble if it determines that all associated clients support it.
CONFIGURING WI-FI MULTIMEDIA
Wireless networks offer an equal opportunity for all devices to transmit data from
any type of application. Although this is acceptable for most applications,
multimedia applications (with audio and video) are particularly sensitive to the
delay and throughput variations that result from this equal opportunity wireless
access method. For multimedia applications to run well over a wireless network, a
Quality of Service (QoS) mechanism is required to prioritize traffic types and
provide an enhanced opportunity wireless access method.
