TFTPD:  Current status of TFTP daemon.  Used for uploading firmware. 
MIR Threshold:  Enable/Disable the Maximum Information Rate (MIR) Threshold.  The MIR Threshold is the 
aggregate throughput on the AP at which the AP will start to enforce CIR rules for SUs.   
Active Channel:  The channel currently being used by the radio. 
RFRX Threshold:  Sets the receive threshold of the AP. The AP will not process signals received below this level, so it 
is very useful for mitigating interference.  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 packets, except ICMP and 
ARP, to reduce the amount of unnecessary overhead introduced into the wireless link.  
SU to SU Communication:  If this AP switch is on, SUs with matching SU to SU groups (except group 0) can 
communicate in peer-to-peer mode via the AP, without the need for a router behind the AP. 
!  
Note: SUs using SU to SU communication must be on the same subnet! 
Broadcast Time Stamp to SU:  If this AP switch is on, the AP will send a copy of the real time clock to the SU every 60 
seconds.  May be used for tracking statistics when using SNMP. 
Remarks:  User definable radio information (i.e. customer name, address of installation, and so on).  Maximum 28 
characters can be stored 
Site Survey Page  
This is a useful tool for detecting interference.  It is not meant as a substitute for a Spectrum Analyzer.  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. Click "Start Survey."  A survey of the default 6 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.
