Point, informing that it is going to transmit the data.
Upon receipt, the Access Point will respond with a CTS
message to all station within its range to notify all other
stations to defer transmission. It will also confirm the
requestor station that the Access Point has reserved it
for the time-frame of the requested transmission.
If the “Hidden Node” problem is an issue, please
specify the packet size. The RTS mechanism will be
activated if the data size exceeds the value you set..
The default value is 2347.
Warning: Enabling RTS Threshold will cause
redundant network overhead that could negatively
affect the throughput performance instead of
providing a remedy.
This value should remain at its default setting of 2347.
Should you encounter inconsistent data flow, only minor
modifications of this value are recommended.
Beacon Interval Beacon Interval is the amount of time between beacon
transmissions. Before a station enters power save
mode, the station needs the beacon interval to know
when to wake up to receive the beacon (and learn
whether there are buffered frames at the access point).
Data Rate By default, the unit adaptively selects the highest
possible rate for transmission. Select the basic rates to
be used among the following options: Auto, 1, 2, 5.5,
11or 54 Mbps. For most networks the default setting is
Auto which is the best choice. When Auto is enabled
the transmission rate will select the optimal rate. If
obstacles or interference are present, the system will
automatically fall back to a lower rate.
Preamble Type A preamble is a signal used in wireless environment to
synchronize the transmitting timing including
Synchronization and Start frame delimiter. In a “noisy”
network environment, the Preamble Type should be
set to Long Preamble. The Short Preamble is
intended for applications where minimum overhead
and maximum performance is desired. If in a “noisy”
network environment, the performance will be
decreased.
Tx Burst Select the check box to enable the Tx Burst function.
802.11g Protection The 802.11g standard includes a protection mechanism to
ensure mixed 802.11b and 802.11g operations. If there is no
such kind of mechanism exists, the two kinds of standards
may mutually interfere and decrease network’s performance.
