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.
Broadcast SSID: Select enabled to allow all the wireless stations to detect the SSID of this
Access Point.
IAPP: IAPP (Inter Access Point Protocol) is designed for the enforcement of unique
as
sociation throughout a ESS (Extended Service Set) and a secure exchange of station’s
security context between current access point (AP) and new AP during handoff period.
802.11g Protection: The 802.11g standard includes a protection mechanism to ensure
mixed 802.11b and 802.11g operation. If there is no such kind of mechanism exists, the two
kinds of standards may mutually interfere and decrease network’s performance.
Tx Power Level: For countries that impose limit on WLAN output power, it might be
necessary to reduce TX (transmit) power. There are 7 TX Power Levels to choose from
