In order to prevent the transmission collision in a hidden nodes environment, Bridge may
send a RTS (Request To Send) before transmitting the data frame and expect to receive a
CTS (Clear To Send) from remote Bridge. You may define a threshold for those frame size
greater than the threshold need to activate RTS/CTS mechanism. The valid range is
between 256 and 2347. Set low value to this threshold may avoid collision, but the
RTS/CTS frame would consume bandwidth. The default RTS threshold value is “2347”.
Note: In Point to Multi-Point application, the transmission collision may be
caused by hidden nodes affection in particular environment or network configuration.
Setting smaller number of RTS threshold could alleviate the hidden nodes problem.
10) Tx Power
Available selection of Transmit Power are Full, Half (-3dB), Quarter (-6dB), and Eighth
(-9dB). Select the appropriate Transmit Power according to the distance and
environmental factor between Bridges. The default setting is “Full”.
11) Auto Reboot
Default is “Disable”, when “auto-reboot” feature is enabled, if near-end AP cannot receive
“alive message” from far-end AP in a certain period. Then, “auto-reboot” will be
automatic performed at near-end AP without notice. The “alive message” is
communicated between near-end & far-end AP via 5GHz bridge links.
12) Click “Save” and then “Reboot” button when you finish setting up for parameter changes
taking effect.
