Active Channel: The channel currently being used by the radio.
RFRx Threshold: Sets the receive threshold of the radio. The radio will not process signals received
below this level, so it is very useful for interference mitigation. For a smaller radius of operation use a
higher threshold (-65 is higher than -70).
Broadcast Packet: This software switch (0) enables/disables the blocking of Ethernet control packet
except ICMP and ARP to reduce the amount of unnecessary overhead introduced to the wireless link.
SU to SU Communication: If enabled (switch 3=on), SUs with matching SU to SU groups (except
group 0) can communicate in peer-to-peer mode through the AP without the need of a router behind the
AP. SUs using SU to SU communication must be on the same subnet.
TCP/IP Service for SU: If enabled, the AP can be accessed via TCP/IP (Telnet or HTTP) from the SU side of
the network via the wireless link.
Remarks: User definable radio information (i.e. customer name, address of installation, etc). A maximum of
28 characters can be stored.
Site Survey Page
The Site Survey page provides a useful tool for detecting and measuring interference. The radio must be
in Opmode OFF in order to use this feature.
Enter the number of minutes desired for the survey, and select the polarization H, V, or E for external
antenna. Click "Start Survey". A survey of the default 8 channels will be performed. Results are
reported in dBm per channel as average and peak. A channel is reported to be "Clear" if the peak and
average are below the RF Rx Threshold by more than 8 dB.
