Advanced Radio Settings
Some of the more advanced radio settings have been moved from the normal Radio configuration page so as to
simplify the configuration process. Care should be taken when making changes to parameters on this page.
TX Antenna
Select which antenna port the module will transmit from. Selections available are Main
Port Only – Messages are transmitted from the main
―
TX/RX port, The Auxiliary port
―
RX is disabled.
Both (Diversity) – Both ports will be used to transmit however not at the same time; it
calculates the best port based on previous transmissions and MAC addressing. Note:
Broadcast / UDP transmission messages will initially toggle between the antenna ports,
and could result in every second message not being heard until the module learns which
device can be reached through which antenna port.
Aux Port Only – Messages will be transmitted via the Auxiliary
―
RX port only
RX Antenna
Same as for TX Antenna above but for the Receiver port. Setting to
―
Both (Diversity)
will allow a high gain antenna to be connected to the Auxiliary
―
RX port which will
give better RX signal gain but not increase the TX gain and possibly pushing it over the
regulatory EIRP threshold.
DTIM Period (AP only)
DTIM sets which beacon frames incorporate extra information for low power sleeping
client devices. Normally set this to 1.
RTS Threshold
“Ready to Send”
RTS frames can be used to help avoid radio collisions between two stations that cannot
directly hear each other. Any frame larger than RTS Threshold bytes will be preceded
by an RTS message. The default value of RTS Threshold is 2346, which effectively
disables RTS signalling, as this value is larger than the maximum frame size
(Fragmentation Threshold).
Fragmentation Threshold
(Client Stations only). The maximum transmission unit (MTU) of data over the radio. If
more than this number of bytes is input into the module, it will be transmitted in more
than one message (or fragmented).
Interference Mitigation
(AP only)
Interference Mitigation should only be turn on (Default is Off) if using Demo Whip
antenna’s or if there is a high level of background interference.
By enabling this option the radio will dynamically adjust radio parameters to help
mitigate interference based on any background interference. It will reduce the receiver
sensitivity and so should only be enabled on paths with a high fade Margin and good
signal quality, etc.
